Overview

Socket Weld Flanges are precision-engineered flanges designed for small-diameter, high-pressure piping systems. The pipe is inserted into the socket area of the flange and joined with a fillet weld, creating a strong and reliable connection.

These flanges provide excellent structural strength, accurate alignment, and reduced leakage risks compared to conventional connections. Their compact design and superior performance make them ideal for applications involving high pressure and critical service conditions.

Veltronova Industries supplies premium quality Socket Weld Flanges manufactured using advanced technology and high-grade materials. Available in various sizes, pressure ratings, materials, and international standards, our Socket Weld Flanges are widely used in oil & gas, refineries, petrochemical plants, chemical industries, power generation, offshore, marine, and process piping applications.
