GOST 12821 Butt Weld Flange , Carbon Steel , Stainless Steel
Description:
A flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework systems. It also provides easy access for cleaning, inspection or modifications. Flanges are usually welded or screwed int such systems and then joined with bolts.
It is the machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices most widely used pipe fittings.
The GOST FLANGE’S types be divided into: SO flange, WN flange, Blind flange
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
