DIN 2632 Welding Neck Flange , ST37 , SS304 / 304L , SS316 / 316L

Description:

A flange is a method of connecting pipes, valves, pumps and other equipment to form a pipework systems.DIN flange include DIN2502,2503,2527,2564,2566,2573,2576,2631,2632,2633,2634,2635, this standard system include Welding neck Flanges, Slip on Flanges, Threaded Flanges, Blind Flanges.

Weld Neck Flanges are flanges that designed to be joined to a piping system by butt welding. the WN Flange is relatively expensive because of its long neck, but is preferred for high stress applications. The neck, or hub, transmits stresses to the pipe, reducing stress concentrations at the base of the Welding-Neck flanges. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck flange. The bore of the Weld-Neck flange matches the bore of the pipe, reducing turbulence and erosion.

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

Applications:

Machinery, petroleum, chemical, water, electricity, shipbuilding sectors piping systems and devices

Competitive Advantage: meet various customer’s demand
