Product Description
Product Overview
Our Socket Weld Raised Face Flange is manufactured in compliance with ASME B16.5 standards, providing a high-strength and leak-proof solution for small-bore, high-pressure piping systems. Designed with a socket-type bore and a raised face sealing surface, it is ideal for applications requiring frequent dismantling and secure connections.
Commonly used in chemical, petrochemical, oil & gas, shipbuilding, and power generation industries, the socket weld raised face flange ensures precise pipe alignment and a smooth bore to minimize turbulence and erosion.
