Advantages of fixed ball valves in industrial applications
In the world of industrial valves, trunnion mounted ball valves have become a popular choice for a variety of applications. Designed to handle high pressure and high temperature environments, these valves are ideal for industries such as oil and gas, petrochemicals and power generation. In this b...Read more -
Why do cryogenic valves use long neck bonnets
Valves suitable for medium temperature -40℃～-196℃ are called low temperature valves, and such valves generally use long-necked bonnets. The long-neck bonnet is used to stipulate that the cryogenic valve includes cryogenic emergency shut-off valve, cryogenic globe valve, cryogenic check valve, LN...Read more -
Why the valve is Galvanized Plating,Cadmium plating,Chrome Plating,Nickel plating
Galvanized Plating Zinc is relatively stable in dry air and is not easy to change color. In water and humid atmosphere, it reacts with oxygen or carbon dioxide to form oxide or alkaline zinc carbonate film, which can prevent zinc from continuing to be oxidized and play a protective role. Zinc is ...Read more -
Why do valve surfaces need coatings
Corrosion is one of the important elements that cause valve damage. In valve protection, valve corrosion protection is an important issue to consider. For metal valves, surface coating treatment is the best cost-effective protection method. 1. Shielding After the metal surface is coated with pain...Read more -
Why Does The Stainless Steel is Rust ?
When brown rust spots (spots) appear on the surface of stainless steel pipes, people are greatly surprised: “Stainless steel does not rust, and if it rusts, it is not stainless steel, and there may be a problem with the steel.” In fact, this is a one-sided misconception about the lack...Read more -

How to Solute the Flange Cracks after Welding
1. Why there is a flange cracks after welding In the production of container equipment, when the stainless steel flange and the cylinder are welded, there will be cracks in the neck of the flange, not at the welding seam. What's the matter? Why is there such a situation?...Read more -
How to Prevent The Valve From Corrosion
Electrochemical corrosion corrodes metals in various forms. It not only acts between two metals, but also produces a potential difference due to the poor solubility of the solution, the poor solubility of oxygen, and the slight difference in the internal structure of the...Read more -
