Stainless steel stub end refers to the forming method of forming a straight wall or flange with a certain angle along the closed or unclosed curved edge by using the function of the mold on the flat part or curved part of the blank. There are many types of stainless steel flanging, and the classification methods are also different. According to the deformation properties, it can be divided into stainless steel short flange and stainless steel long flange. Wanhua's production of stainless steel flanging is also a type of steel butt-welded pipe fittings, which is generally a section inside a loose sleeve flange. Because the flange is often used in cases where the medium temperature and pressure are not high and the medium is corrosive. When the medium is highly corrosive, the part of the flange that contacts the medium (flanging) is a corrosion-resistant high-grade material such as stainless steel and the outside is clamped by a flange ring of a low-grade material such as carbon steel to achieve sealing . The stainless steel flanges produced by our company are according to GB / T12459-2005 and GB / T13401-2005.
When quoting stainless steel flanging, you must accurately inform the pressure of the pipe used, or directly inform the wall thickness of the flanging, so that the accurate price can be reported. The conventional expression of flanging wall thickness is sch10s, sch20s, etc. Different pressure levels represent different thicknesses, you can refer to the pressure level wall thickness table.
Use of stainless steel flanging: petroleum gas pipeline engineering, natural gas pipeline engineering, chemical plants, power plants, shipyards, pharmaceuticals, dairy products, beer, beverages, water conservancy, etc.
