Product Description

We are hebei JiMeng high-pressure flange pipe group co., LTD., our group is a professional production and sales in north China the flange, elbow, pipe fitting one of large enterprises.Main standard gb, the mechanical, chemical, manhole, vessel standard, Japanese standard, German standard, American standard, the standard, British standard and other standards flange, elbow, tee, reducer, etc.Today I for everybody to introduce in detail the purpose of the white steel flange and features:


White steel flanges and stainless steel flange, the two familiar.But he had another unfamiliar name: high speed steel flange.White steel workers in the factory the mouth is also called as "feng steel", which in addition to making the flange, tool factory, cutting tool, the enterprise also produce all kinds of knife billet with it.Knife after grinding, white light, therefore is called "white steel knife"


White steel flange as a kind of pipe connecting parts, the most common in pipeline engineering.In need of connecting pipe joints, install each flange, two pieces of flange sealed shim between the two (different pressure or type of flange need different styles of sealing gasket), and then in the flange bolt hole put on bolt fastening.Different pressure of white steel flange its flange thickness and the use of bolt is also each are not identical.Low pressure pipeline can use wire connect flange connection, more than 50 kilograms of pressure pipe welding method must be used for connection, lest cause unnecessary loss pipeline rupture.


White steel flange has the very high toughness and abrasion resistance and impact resistance performance, bending strength, impact toughness and ordinary carbon steel flange at the same level.But life is 2 times more than ordinary carbon steel flanges.But the price is more expensive than the general carbon steel flanges.
