Thermal insulation valves: ball valves feature, principal, installation,advantageous

Thermal insulation valve

Insulation valves take good insulation measures for a large number of valves in industrial production, which can not only achieve good energy-saving effect, but also improve the safety and reliability of valves and prolong the service life of valves.

Flanged Jacket EN Inculation Ball Valve: Stainless steel CF8, PN16 DN80, Insulation mediam: steam with pressure 4bar

The insulation valve has good insulation and cooling characteristics, and the diameter of the valve is the same as the diameter of the pipe. At the same time, it can effectively reduce the loss of medium heat in the pipeline. It has good heat preservation and cooling characteristics, and can effectively reduce the heat loss of medium in the pipeline.

Reasons for Rust of Stainless Steel Valves and Solution for Anti-rust

I. Reasons for Rust of Stainless Steel Valves

To test whether stainless steel valves will rust, we can put the same valves in different environments to verify and compare. Generally speaking, if stainless steel valves are placed in relatively dry environments, after long time, the valves are not only as good as new, but also not rusty. But if the valves are placed in seawater containing a lot of salt, they will rust in a few days. Therefore, the corrosion resistance and stainless of stainless steel valves also need to be limited by the use environment. In addition, from the characteristics of stainless steel valve itself, it is stainless because there is a layer of chromium-rich oxide film on its surface to prevent particles such as oxygen atoms from invading and damaging objects, which makes it stainless. But when the film is destroyed by environmental factors, as oxygen atoms enter and iron ions free, stainless steel valve will produce rust.

Several Reasons  and Preventive Measures for Flame and Explosion of Oxygen Valve, Pipeline Valve 

Several Reasons  and Preventive Measures  for Flame and Explosion of Oxygen Valve, Pipeline Valve 

With the increase of oxygen consumption, oxygen pipelines are used for transport large oxygen. Owing to the long pipeline and wide distribution, combined with the quick opening or quick closing of valves, accidents of combustion and explosion of oxygen pipelines and valves occur from time to time. Therefore, it is essential to comprehensively analyze the hidden dangers and dangers of oxygen pipelines and cold valves and take corresponding measures.

Oxygen Valve sets include oil-free bronze ball valve, stainless steel Axial check valve, stainless steel Axial flow control valve : Valve Packing box/neck should be insulate with site air

Technical Requirements for Boiler Forging Valves-Raw Material

Technical Requirements for Boiler Forging Valves 

1. Forging raw material should be accompanied by quality certificates (also known as quality assurance certificates). Supplementary inspection should be carried out when there is no quality assurance certificate. Only those who are qualified can be put into production.

2. Forging pieces (referring to raw materials for forging) may be rolled (e.g. round steel) or ingots. If the forged blank is rolled, its surface quality and chemical properties will be improved.

cryogenic application of metal sealing butterfly valve

Cryogenic application of metal sealing butterfly valve

With the rapid development of industrial technology, the valve industry made more stringent requirements, especially for use in cryogenic medium butterfly, in addition to meet the general performance of the valve with a normal condition and, more importantly, in the low temperature under the valve seal reliability, flexibility and movement of cryogenic valves some other special requirements.

Because butterfly valve with a compact, small size, light weight (with the same pressure, the same diameter of the valve can reduce by 40% compared to 50%), fluid resistance, open and close rapidly, such as a series of advantages, it is widely used.

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.
