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.

wafer-Lug stainless steel manual knife gate valve and wafer-flange carbon steel Pneumatic Knife gate valve

The wide application of stainless steel knife gate valve results from its own characteristics. Firstly, it has good sealing effect and good elasticity of U-type seal gasket; secondly, its full-diameter design has strong passing ability; thirdly, like an knife, it has good breaking effect and can effectively solve the leakage phenomenon after the breaking of the gate containing block, particle and fiber medium; Forth, the knife gate valve are light weight and small room needed; finally, it does not need to remove the valve because of its convenient maintenance without replace the valve seal.

SGV order for Europe plant: Stainless steel knife gate and Carbon steel knife gate valve are bonnet less design: refer MSS SP81 or JB/T8691 (Similar with MSS SP 81 but have more clear definition)

Well protected Valve Packing , Suitable for long distance air and sea transportation.

The order have 2 part：
Wafer-lug /wafer flanged type Risting stem Pneumatic Knife gate valve

Taboos and Measures of Drainage Valve Pipeline Construction

Taboos and Measures of Drainage Valve Pipeline Construction

1: The main materials, equipment and products used in construction are short of technical quality appraisal documents or product certificates that meet the current standards issued by the state or ministry. Consequences: The quality of the project is not up to standard, there are hidden dangers of accidents, can not be delivered on time for use, must be repaired, resulting in delays in the construction period, increased investment in labor and materials. Measures: The main materials, equipment and products used in water supply, drainage and heating and sanitation projects shall be technical quality appraisal documents or product qualification certificates issued by the state or ministry in accordance with the current standards; the product name, model, specifications, national quality standard code, date of departure, name and location of the manufacturer, inspection certificate or code of the manufacturer shall be marked.

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

Mol, Thyssenkrup to establish polyol site in Hungary

TISZAUJVAROS,  Hungary—Mol Group and Thyssenkrup Industrial Solutions have signed an agreement to establish a polyol complex in Tiszaujvaros.

The manufacturing complex is planned to be operational by the second half of 2021. The firms said ground works and basic construction activities are set to begin in the fourth quarter of 2018.

The complex will have a polyether polyol production capacity of 200,000 metric tons per year when fully operational and will represent a $1.4 billion investment. Mol said the project represents its largest investment.

Mol Group is an integrated, international oil and gas company, headquartered in Budapest, Hungary. It is active in more than 30 countries with a dynamic international work force of 26,000 people.

Environmental cupola is still energetic： STATE OF THE U.S. CUPOLA INDUSTRY

In recent years, the requirement of energy saving and emission reduction has been increasing and strictly implemented, so many people believe that the application of cupola is declining day by day, and it is an irreversible trend to be replaced by induction furnace. In reality, a large number of cupolas have been banned, and the wind that cupolas will be completely withdrawn from the field of foundry is also very noisy.

Is the cupola really useless? Where on earth has it been criticized by the public? Faced with a comprehensive ban, who in the world did the cupola provoke?

Environmental cupola 

Cancellation of cupolas in SMEs does not affect their importance
