Carbon Steel / Stainless Steel Flat Welding Flange With BS4504

Description:

BS flange is a flange system from England, which have flange type including Welding neck Flanges, Plate Slip-on Flanges, Screwed Boss Flanges, Slip on Boss Flanges, Blind Flanges etc.

Slip on weld flanges are slipped over the pipe and welded (usually both inside and outside) to provide strength and prevent leakage. Slip-on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These SO flanges can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube.

Flange materials is Carbon steel , stainless steel.

Accordance with the processing methods be divided into: Forged flanges, Steel flanges, Cast flanges

Flanges production process:

1) Forged Flanges: The steel bar according to different specifications, models, Saw cutting into the reverberatory furnace heating, then by forging presses, pneumatic hammers and other forging machinery and mechanical processing, typing, anti-rust treatment for the lacquer, rust oil, hot dip galvanized.
2) Steel Flanges: According to the flange size by punching or stamping steel plate with a gas cutting machine cut type. Then be machined, typing, rust treatment is lacquer, anti-rust oil, hot galvanized.
3) Cast Flanges: IF electric furnace steelmaking, after molten steel melt into the molding of different sizes, and then machining, typing, anti-rust treatment for the lacquer, rust oil, hot dip galvanized.
