Schlumberger introduces integrated seat technology ball valve



HOUSTON — Schlumberger announced today the release of the GROVE IST integrated seat technology ball valve. New ball valve technology features a patented seat-on-ball design that significantly improves performance over conventional metal-seated ball valves in addition to offering considerable size and weight benefits.

“As the industry deals with more demanding reservoir conditions, conventional trunnion-mounted ball valves have only been slightly modified in design to adapt to these challenging environments,” said Brent Baumann, president, Valves & Measurement, Schlumberger. “The GROVE IST ball valve introduces a disruptive technology uniquely designed to mitigate the risk of leakage at higher pressures and temperatures and to save operating cost.”

Conventional ball valves tend to become larger in size and weight as oil and gas companies explore harsher environments. The GROVE IST ball valve overcomes these conditions with its game changing seat design that provides advanced sealing performance and increased valve life span while minimizing size and weight, enabling customers to reduce total cost of ownership.

The GROVE IST ball valve has undergone an extensive qualification test program that qualifies the full product range to API 6A PR2 for performance, API 6AV1 for slurry testing and API 607/6FA for fire testing. In addition, in-line flow testing validation was performed at an independent, accredited testing facility to further simulate real operating conditions.


Butterfly Valve API 609 Category B

What does the American Standard Butterfly Valve API 609 Category B mean?

   API 609 is the design standard for the American standard butterfly valve, which specifies the structure length is divided into Category A and B, in Chinese is the structure length of API 609 A butterfly valve and B butterfly valve, also called the body length. Also different in design/Inspection. Here we focus on Face to face of API609 Valve.
Butterfly valves are categorized according to their structure. Nowadays, there are more midline/center line butterfly valves and eccentric butterfly valves on the market. The standard length of the American standard butterfly valve used in the center line butterfly valve is the API 609 Class A butterfly valve. The eccentric butterfly valve is mainly a three-offset butterfly valve. The structure length standard adopted is the Class B butterfly valve regulated by API 609.
The Class B butterfly valve of the API 609 standard specifies the structure length of the American standard butterfly valve, flange butterfly valve and lug butterfly valve. In comparison with the national standard GB butterfly valve, the flange butterfly valve and the national standard butterfly valve structure length is same, but there is a gap between the clip butterfly valve, especially the 6 inch, 8 inch difference between the two specifications/standard  is largest. This is also an way to judge a manufacturer is they are professional  in produce American standard  butterfly valve.
In the API 609 Category B, the 6-inch to 150LB butterfly valve is specified, the structure length is only 57mm, and many manufacturers, or 70mm, is the same with the national standard valve body, it can be seen that many American standard butterfly valve manufacturers directly to use the national standard valve mold. The valve body was modified to the American standard connection size.
Our American standard butterfly valve has a unique set of molds, which are designed and manufactured according to API 609 and other related regulations. Therefore, regardless of the valve body thickness, flange thickness, and structural length can reach the relevant standards.

Perfect repair of large size gate valve

Perfect repair of large size gate valve
The waste valves replaced from the working site are corroded by various media, fluid pressure, and affected by different temperatures. The parts including the valve body are affected by different degrees and different locations and cause valve malfunction. The drop cannot even be used. However, the used old valves that have been ineffective at the “validation” are not worthless and have no remediation value. They cannot be repaired and used, as long as they use the principles of metal structure, dynamics, fluidics, corrosion protection, welding, and heat treatment. Knowledge, the provision of essential maintenance equipment and the establishment of an experienced professional team, can fully implement deep-level, high-grade, high-quality repair and refurbishment of used valves.
The quality problem and situation for gate valve

In Jun 2017, there were 4 pcs wedge gate valve PN25 dn500  WZ41H-PN2.5MPa in the water supply circulation system of Sichuan Jiuda Group vacuum salt making equipment. The nominal diameter DN500mm gate valve was replaced by a large amount of leakage and sent to our maintenance (only one for example) .

After the dismantling check, a large area of erosion corrosion occurred on the valve body, the gate plate and the sealing surface at the lower part of the valve inlet. The valve body has 120mm2 of corrosion, the depth is 20mm, the gate plate has 300mm2 corrosion, the depth is about 22mm, the sealing surface It is completely eroded.

The valve body and gate plate A216 (WCB) of the valve, this type of carbon steel harden tends to be harder, welding is easy to produce cold cracks in the weld, welding performance is poor.

The sealing surface of the valve body and the sealing surface of the stem are A182-F6a, which is a martensitic stainless steel. It is easy to produce hard and brittle martensite in the welding process, resulting in hardening and embrittlement of the weld and heat affected zone. , poor welding performance.

The valve is a large piece, the structure is rigid, easy to produce cracks, strict repair welding process.

Repair measures:

According to the working conditions of the valve, the contact medium and mechanical processing and other factors, the CHSo52 stainless steel electrode (Atlantic brand series electrode) with good comprehensive performance and resistance to chloride ion corrosion was selected to perform surfacing welding on the sealing surface of the valve.

Before repair welding, first deal with surface pits, sharp corners and other defects, and then polished smooth and smooth.

Because of the poor weldability of the valve body and the gate base, a transition layer must be added between the base and the surfacing layer to reduce or avoid the risk of cracks. The mechanical properties of the weld can also be satisfied.

First, use A302 stainless steel with good plasticity and toughness to make the transition, and then fill it with J507 low hydrogen electrode with good heat resistance, so that the strength of the weld is the same as that of the substrate. When the transition layer is surfacing, first weld the place where the weld is uneven, and then begin the surfacing from the bottom of the groove. The weld is gradually expanded outwards from the spiral shape, and the short arc arc welding is applied. The thickness of the weld bead is about 4 mm. We strictly control the specification during welding and avoid stress concentration. For overlay welding, the same surfacing method as the transition layer is used. The height of surfacing is the same as the surface

Although the damaged valve body and the sealing surface of the valve vane have been removed and no longer exists, surfacing is still performed in the original arc. Starting from the starting point of radius R, a short-arc arc breaking arc welding method is used for welding. The weld bead was widened by 6mm on the basis of the original sealing surface, and the highly surfacing layer was 3mm higher than the original sealing surface to facilitate machining.

The gate sealing surface is machined on a lathe with special tooling, and the valve body sealing surface is specially processed with the VRM’s patented maintenance equipment.

After the assembly of the valve, the strength of the valve body and the test pressure of the sealing surface, etc. are in full compliance with national standards and the customer is very satisfied.

Enviromental protection requires valve to be low-leakage( Fugitive Emission Valve)

Environmental protection
Valve in the use of the process , environmental impact is an important indicator of the performance of the valve. Valve low valve leakage is an important parameter to evaluate the environmental protection performance. Valve low leakage requirements have become the basic requirements the valve design and manufacturing. Usually means  Fugitive Emission Requirment for valve.
In 2015, for the first time, API600 standards which was widely used in the valve industry , the valve low leakage test requirements API624 been joined the standard text. China National Standard (GB) hydrotreating device with the valve standard has also been clearly required in accordance with ISO15848 low leakage detection.
low leakage standards widely used in the valve field are ISO15848, VDI2440, API624, MESC SPE77 / 312 and so on. These standards are carried out in the form of proton spectroscopy with helium or methane gas as a leak detection medium, typically at a level of 10-12 Pa * m3 * s-1.
Low leakage detection and evaluation requirements, will promote the accuracy of the valve processing and continue improve sealing quality standards , low leakage valve will gradually become the mainstream of high-end valve market.

For example, an  Fugitive Emission test for gate valve, usually means bonnet machining accuracy and stem accuracy packing material, middle flange gasket casting quality should be attentionned,

AUMA supplied actuators for Finnish CHP revamp

Sep 22th, 2016

AUMA Finland Oy has recently supplied around 125 electric valve actuators with Profibus DP-V1 for an upgrade project at a combined heat and power (CHP; cogeneration) plant at a steelworks in Finland. The Raahen Voima plant is located at Raahe, 500 km north of Helsinki.

The project, which has a total investment value of EUR 121M, involves replacing the existing boiler and steam turbines. The new boiler will run on coke and process gas from the steelworks, with natural gas as a support fuel. Thanks to new technology and cleaner fuels, it will provide 20–25% more electricity than the previous plant while reducing emissions. Startup is scheduled for autumn 2016. The new plant operates at steam conditions of 545°C and 83 bar, and will produce 125 MW of electricity and 40 MW of steam for district heating.

Working closely with SSAB Europe, AUMA Finland Oy chose AUMA SA multi-turn and SQ part-turn actuators with intelligent AC actuator controls. The use of the Profibus DP-V1 protocol allows the control system to change the actuator settings and request diagnostic information while the plant is running – a feature that is not available with standard Profibus DP-V0. – See more at:

Maintenance and Troubleshooting for natural gas pipeline ball valves

Pipeline ball valve maintenance and management techniques
1. Maintenance and management of the construction period
During the construction period of the ball scientific management and maintenance is very important in the construction of the equipment management in place, maintain science, not only can ensure safety, and can greatly reduce the construction and operational management of costs. Major should note the following aspects: ① to the correct method of handling the valve, the valve to avoid mechanical damage. When the valve lifting, lifting belt can not be tied to the stem or actuators lifting, otherwise it will cause the stem bending diameter valve seal failure and gearbox destruction; ② in the factory, to be installed at both ends of the valve simple blind board to avoid during transport and on the construction site water, sand and other impurities into the valve chamber, causing corrosion and damage to the seal; ③ at the construction site, the best valve neatly placed on the sleepers, do not put anywhere, avoid sewage mouth, mouth, and other grease from being damaged or broken; ④ before installation, the valve must be grease injection. By injection of grease on the one hand to check the grease channel is smooth, on the other hand to seat sealing surface and the rear cavity is filled to avoid impurities into the sealing surface and a rear chamber, while a certain extent, can weaken the welding of high temperature on the valve seat after ⑦ pressure test done; damage; ⑤ the entire installation process to keep the valve in the fully open position; ⑥ when the welding is completed and finished water pressure test before and after each operation and to timely make a certain amount of grease , to the valve chamber timely discharge water clean, prevent corrosion and freezing.

2. Running routine maintenance and maintenance recommendations
① periodically check tightness of valves, sewage through the mouth to check if there is internal leakage, internal leakage press handler for processing; ② timely injected a certain amount of fresh grease to the seat, the amount and frequency of injection valve in accordance with the frequency of activities, generally when the valve event once, to inject the right amount of grease, the amount of each injection is approximately 1/8 the volume of the sealing system, this was done to avoid the greatest degree of impurities inside the tubes into the seat chamber, the impact of the valve seat, thus resulting in seal failure, while ensuring the sealing surface time in the “wet” state; ③ valve of little activity, the minimum annual activity 1 times while injecting the right amount of grease, this is done to avoid the ball and when gluing the seat, but also to avoid the ball to dry milling activities, protects the seat and ball; ball before ④ winter to conduct a comprehensive maintenance and repair, the focus should drain valve actuator within the cavity and water, to avoid freezing in winter , affecting the normal function; ⑤ replace the grease once a year within the gear transmission mechanism; ⑥ periodically check valve diameter seal, once the leak appeared to be in time; ⑦ remove rust, external maintenance.

Russian media IS penetration of Central Asia natural gas pipeline to China pose a direct threat

Common Faults and exclusion method
1. Ball endoleak
Gas pipeline within the valve leakage is the most common valve problems.
Reason (1) within the valve leakage
1) Construction of the cause of the valve leakage: ① transport and lifting the overall damage caused by improper valve causing the valve leakage; ② When the factory, there is no pressure applied to the valve be dried and preservative treatment, resulting in the formation of the sealing surface corrosion internal leakage; ③ construction site protection is not in place, both ends of the valve is not installed blind, rain, sand and other impurities into the seat, causing leakage; ④ when installed, no grease injection valve, causing impurities into the rear seat when welding or burns caused by internal leakage; ⑤ valve is not installed in the fully open position, causing damage to the ball, during welding, if the valve is not fully open position, weld spatter sphere will cause damage, when accompanied by weld spatter sphere when the switch will cause further damage to the valve seat, causing internal leakage; ⑥ welding slag and other construction remnants cause the sealing surface scratches; ⑦ shipment or installation of the limit inaccuracies caused by leakage, if the stem or other accessories with the drive sleeve assembly angular displacement, the valve will leak.
2) Run of the cause of the valve leakage: ① The most common reason is that managers take into account the operational and maintenance costs more expensive valve without maintenance, or lack of scientific approach to management and maintenance of the valve without valve preventive maintenance, caused by equipment failure occurred in advance; ② no maintenance or improper operation caused by internal leakage in accordance with maintenance procedures; ③ during normal operation, construction remnants scratch the sealing surface, causing internal leakage; ④ pigging improper sealing surface damage caused by internal leakage; ⑤ long-term maintenance or inactivity valve, causing the valve seat and ball lock, resulting in seal damage when the switching valve is formed in the drain; ⑥ valve switch caused by inadequate internal leakage, regardless of any valve opening and closing position, the general inclination 2 ° ~ 3 ° may cause leakage [2]; ⑦ large number of large diameter valve stem has a stop block, if used for a long time due to corrosion and other reasons between the stem and stem stopper accumulation will rust, dust, paint and other debris, the debris will cause the valve can not be rotated into place and cause leaks – If the valve is buried, the stem will produce longer and more falling rust and impurities impede ball rotation in place, causing valve leakage, ⑧ general the actuator position is limited, if long-term cause rust, hardened grease or loose bolts limit will limit inaccurate, causing internal leakage; valve actuator position ⑨ set forward, not about the place causing internal leakage; ⑩ lack of periodic maintenance and repair, resulting sealant becomes dry, hard, dry seal fat accumulation in the resilient seat, seat impede movement, resulting in seal failure.
Corner gas processing plant China largest natural gas treatment plant put into operation in the Sulige gas field
(2) judging method endoleak
Natural gas pipeline is fixed common axis valve, which generally check is: turn the valve to the fully open or fully closed position by the sewage discharge check valve nozzle for leaks. If it can discharge clean, then the proof sealing. If the discharge pressure is always there, it can be considered a leak valve, then the valve should be handled accordingly. But emphasized that for GRoVE B-5 and B-7A-ball, PBV ball, ROBERT CORT ball can only be checked in the fully closed position, such as on the ball valve to open a channel, when the fully open position when, to balance pipeline and the valve chamber pressure. But when the fully closed position, it will not happen.
(3) endoleak handler
① first check valve limit to see if the limit can be resolved by adjusting the internal leakage of the valve. ② first injected a certain amount of grease see if you can stanch, when the injection rate must be slow, while observing the changes in the outlet pressure gauge pointer grease gun to determine the case of internal leakage of the valve. ③ If you can not stanch, there may be early injected sealant harden or sealing surface damage caused by internal leakage. At this time recommendation injection valve cleaning fluid, and the sealing surface of the valve seat cleaning. Usually a minimum of half an hour soak, soak if necessary, hours or even days, to be cured completely dissolved and then do further processing. In this process, it is best to switch movable valve several times. ④ refilling grease, intermittent opening and closing the valve, the discharge valve after the contaminants chamber and the sealing surface. ⑤ In the fully closed position to check if there are leaks, sealing grease should be injected to strengthen the level, while opening the valve cavity vent, which can generate a large pressure differential helps seal, under normal circumstances, to strengthen the level by injecting sealant internal leakage can be eliminated. ⑥ If you still have internal leakage, it is necessary to repair or replace the valve.
2. Stem leakage
Most valve stem is provided on the upper and lower two seals, in general, you can not do any maintenance, but due to prolonged wear or aging, may cause leakage of the valve stem. For injection stem population, can be achieved by injecting sealant temporary stanch purposes. Fill sealing grease should be slowly, preferably with a manual grease gun. When the leak stops, they should stop filling, filling volume too much can cause difficulties stem rotation. Of course, some of the stem at the structure of by injection or compression packing gland packing to achieve the seal.
3. Ball valve operation exception
1) ball a long time without maintenance and activities, and the ball seat may be locked, this operation of the valve even more laborious operation does not move, then it is best injected a certain amount of cleaning solution soak for some time before the operation.
2) pipeline in the garbage, sand, dirt or aging, hardened fat accumulation in the seat ring seal around the valve seat and the impact of the action, causing the seat ring stuck, causing a leak between the valve seat and the ball. Typically injection valve to the cleaning solution to remove impurities.
3) When the high water content of the natural gas in the transport process as the environment changes, there will be condensate water. The water valve will exist lowest point of the valve, it is usually the lower part of the lower pivot or ball valve, freezing cold conditions at low temperature, resulting in the valve opening and closing does not move.
4) when dealing with stem leakage, causing clamping screws too tight on the switch difficult, the compression screw should not be too loose or too tight.
5) There may also be adopted for the turbine, worm gear operated valve engaging the following reasons: ① badly worn or broken teeth, resulting in the engagement can not be normal; safety pin ② worm on the break; ③ worm or worm wheel bearing damage on; ④ turbine worm poor lubrication for grease these places usually petroleum based, are water pollution, in cold weather, the water freezes, the valve inoperable. If this occurs, open the gear box to remove all ice, water and grease contaminated, and re-apply new grease – if particularly cold, it is best to use low-temperature grease, such as alcohol-based grease ; ⑤ bolt and valve gearboxes are connected to the loose or cut; ⑥ electric head fault, no power supply wiring or setting errors.
6) There may also be linked to gas and liquid valve for the following reasons: ① gas line, oil pipeline may block or rate-limiting valve is in a closed state; ② lack of air pressure; ③ cylinder or rotary component sealing fault; ④ pressure and other causes of excessive torque.

Offshore oil platform

In order to improve the reliability of the valve, to extend valve life, good early, especially maintenance and supervision of construction and commissioning period is very important. Therefore recommended that: ① to strengthen the device before delivery maintenance oversight and supervision during transportation; ② strengthen supervision before the equipment installation and maintenance, maintenance and installation process; ③ before installation, pressure test must be carried out, as soon as possible identify problems and early treatment; ④ change the concept of preventive maintenance, periodic maintenance program to develop and strictly implement; ⑤ strengthen professional training to improve the professional quality of maintenance personnel, so that maintenance of scientific, regulatory and safety; ⑥ the establishment and improvement factory equipment, transportation, installation, testing, use of maintenance, maintenance accounting for future management make a record and accumulation of raw data; ⑦ were trial and error, the establishment of relevant scientific maintenance procedures and inspection standards.

Iran: no oil output freeze until it restores pre-sanctions level

Iran won’t consider a Crude oil production freeze until it reaches its pre-sanctions level of output of 4.2 million barrels a day, a senior energy official said Thursday.

Mehdi Hosseini, who heads the oil contracts revision committee at Iran’s Petroleum Ministry, said a freeze at anything less than that would be a continuation of the sanctions imposed on his country as a result of its disputed nuclear program.

“Our pre-sanction production was something around 4.2 (million barrels per day), and our exports was something around 2.5, 2.6 (million barrels per day) or so” Hosseini said on the margins of an oil conference in Paris. “Therefore any other figure less than that it means another sanction against ourselves. It is something we cannot accept.”


The statement is in line with Iran’s previous comments on the issue and comes after the country stayed away from a global producers’ meeting last weekend on whether to freeze production. With many international sanctions lifted under its nuclear deal with the U.S. and other world powers, Iran began exporting oil into the European market again and is eager to claw back market share. It produces 3.2 million barrels of oil a day now, with hopes of increasing to 4 million by April 2017.

The failure of last weekend’s meeting to yield any agreement dominated the conference’s morning sessions, with one audience member asking whether OPEC, an economic alliance of oil producing nations, had become a “zombie organization.”

“I heard many times that OPEC was dead,” OPEC Chairman Abdallah Salem el-Badri told participants. “OPEC will be around as long as there is oil in the ground.”

Outside the venue, around 30 demonstrators shouted slogans against fossil fuels and climate change, chanting: “One, two, three degrees — it’s a crime against humanity.”
