Forging Process And Application Of Welding Flange.

Forging Process and Application of Welding Flange.Yesterday, the customer sent a flange inquiry sheet, our foreign trade sales salesman found that the flange product description in the inquiry sheet was not too detailed, the customer just simply wrote the welding flange, our foreign trade sales salesman sent an email to the customer to detail the flange product description. What is a butt welding flange? The welding flange includes long neck welding flange, flange, etc. It is mainly applicable for the matching welding of flange and pipe. Its welding has reasonable structure, large strength and stiffness, and can withstand high temperature, high pressure and repeated bending and temperature fluctuation; while its sealing performance is reliable. the welding flange with nominal pressure of 0.25~2.5MPa adopts concave and convex sealing surface. Generally speaking, the butt welding flange is worn with a neck and has a round pipe transition and is connected with the pipe butt welding flange.welding flange is a kind of flange pipe fittings, which is widely used and promoted in different fields and industries. It is applied in different ranges and needs different environments, and needs to be used according to certain conditions. The sealing surface of the welding flange can be made into smooth type, concave and convex type and tenon type three kinds, the smooth type of the weldinug flange application amount is large, mostly used in the case of relatively moderate medium conditions, such as low-pressure non-purified compressed air, low-pressure circulating water, its advantage is relatively cheap. Repair welding flanges are suitable for pipelines with large fluctuations in pressure or temperature, or pipelines with high temperature, high pressure and low temperature, and also for pipelines conveying expensive, flammable and explosive media. The welding flange is used in the environment where medium condition contrast is relaxed, such as low-pressure non-purified compressed air, low-pressure circulating water, its advantage lies in the cheap price comparison.
