Alloy Steel DIN 2634 PN25 Weld Neck Flanges

Alloy 20 DIN 2634 PN25 Weld Neck Flanges

DIN 2634 PN25 Weld Neck Flanges are suitable for piping systems where the operating pressure is nominal 25 bar (362 psi). They are usually forged out of carbon steel (e.g., C22.8), stainless steel (e.g., 1.4301/1.4571), or alloy steel, depending on the application. Weld neck flanges have a long taper hub that delivers stress to the pipe, minimizing the chances of fatigue failure. Their mechanical characteristics encompass tensile strengths of 400 to 600 MPa and good weldability. These flanges are designed for butt-welded applications, and they provide excellent leak-proof performance during thermal and pressure cycling.
