  • Raised-face design ensures secure seal
  • Socket-weld connection suits Schedule 40 pipe

Product Identity

The Value Brand Flange Socket Weld Flange is a 2-1/2 inch nominal pipe size fitting designed for welded pipeline assemblies. It suits installers and maintenance teams who need a raised-face steel flange rated for Class 150 service.

Installation Notes

The flange connects by socket welding to Schedule 40 pipe, requiring standard welding preparation and alignment with the 5-1/2 inch bolt circle. Misalignment of the four 3/4 inch bolt holes or incomplete weld penetration are the most common issues that lead to leaks or stress concentration.

Critical Specification

The fitting carries a maximum operating pressure of 150 psi across a temperature range of -29 to 425 degrees Fahrenheit, making this pressure-temperature envelope the decisive factor for selecting the part.
