Stainless steel gate valve application field

Valve is a kind of control element in various medium conveying systems in pipelines. It is widely used in chemical, petrochemical, petroleum, paper, mining, electric power, liquefied gas, food, pharmaceutical and drainage industries. In changing the direction of medium flow, it has the functions of diversion, cut-off, adjustment, throttling, check, diversion and pressure relief. It is an indispensable and important accessory in all walks of life. So what are the advantages and characteristics of stainless steel gate valves?

With the continuous increase of social demand, the types of stainless steel gate valves have become more and more diverse. From civil to industrial fields, the production quality of stainless steel gate valves has reached the point of excellence. Especially in the petroleum and chemical industries, the demand for gate valves and product types have a lot of room for development. However, due to the diversity of market quality, gate valves need to make some appropriate product references before buying, such as gate valves. Whether the flow resistance meets the standard, whether the discharge force of the gate valve is smooth and free, whether the sealing level of the gate valve is strict, and how long the service life of the gate valve is.

In addition to the basic knowledge before purchase, we should also pay attention to the reasonable maintenance and maintenance of the gate valve during use. For example, the inner cavity of the gate valve should be cleaned regularly, and there should be no residues and aqueous solutions. The outside of the gate valve should be clean and tidy and free of oil stains. ; The sealing surface of the valve, the valve stem, the valve stem nut, and the machined surface must be coated with a certain amount of anti-rust or grease; at the same time, avoid human impact, handling and disassembly; for long-term shelving The gate valve should be inspected and maintained regularly.

From the point of view of the production material of stainless steel gate valve, it is mainly divided into 301, 304, 316, 304L and 316L. Among them, 304 stainless steel is one of the common materials in the production of stainless steel gate valves. It contains more chromium, has a matte surface, and is not easy to rust. It is a very good gate valve plate. 304L is a stainless steel with low carbon content, it is mainly suitable for welding work occasions.

316 is mainly used in food, industry, medicine and surgical equipment, etc.; 316L is widely used in the chemical industry because of its high corrosion resistance; although we cannot distinguish its product texture from the naked eye, but Knowing about it before buying will make our purchase process more enjoyable.
