DIN 2632 Description

The DIN 2632 standard specifies weld neck flanges for low-pressure applications in PN10 class piping systems. These flanges are designed to be butt-welded to the pipe, offering a strong, leak-proof connection suitable for water, steam, and mild chemical service.

Key Feature: Long tapered hub reduces stress concentration at the flange–pipe joint, making it suitable for repeated temperature/pressure cycling.
