Common types of stainless flanges
The function of welded steel stainless steel flange is to butt weld the flange and pipe. The structure is reasonable, the compressive strength is high, the bending stiffness is large, and it can withstand ultra-high pressure, continuous bending and temperature fluctuations, and the sealing performance is reliable.
Flat welding steel flange is applicable to galvanized steel pipe connectors with rated working pressure not exceeding 2.5CPa. The sealing surface of welding flange can be divided into smooth type, convex concave type and tenon groove type. Among them, vertical welding flange is suitable for use. Most of them are used for soft substances such as bottom pressure air compression, bottom pressure cooling circulating water. Its advantage is that the price is relatively cost-effective.
Loose flange is commonly known as looper flange, which is divided into welding looper flange, flanging sleeve flange and opposite welding sleeve flange. It is common in the condition that the material temperature and working pressure are not too high and the material has corrosion. When the material is etched, part of the material touched by the flange is a kind of anti-corrosion advanced raw material, such as stainless steel plate, while the outside world uses carbon steel flanges and other raw materials to complete the sealing.
The pipe with PN ≤ 10.0MPa and DN ≤ 40 is often used for socket welding flange.
Integral flanges are generally integrated with machine equipment, pipelines, spare parts, gate valves, etc. This kind of machine equipment and gate valves are generally used in machine equipment and gate valves.
