Product Overview

Weld Neck Flanges

Shatrunjay Special Alloy is acknowledged as a manufacturer, exporter & suppliers of Weld Neck Flanges and Stainless Steel Flanges (Gr. 304, 304L, 316, 316L) available in a variety of grades, materials, and finishes in both metric and inch sizes. These Weld Neck Flanges are manufactured using materials such as Carbon Steel, Stainless Steel, Alloy Steel, Duplex Steel, Inconel, Monel, Hastelloy, and Copper Nickel alloys in India and Asia, conforming to international flange specifications.

Weld neck pipe flanges are connected to the pipe by welding the pipe to the neck of the flange, which helps transfer the stress from the weld neck to the pipe itself. This reduces high stress concentration at the base of the hub of the flange. Weld neck pipe flanges are generally used in high-pressure applications where hot or cold temperatures exist. The inside diameter of a weld neck pipe flange is machined to match the inside diameter of the pipe, ensuring smooth flow and improved structural strength.

  • Designed for high pressure and high temperature applications
  • Strong welded connection for superior structural strength
  • Reduces stress concentration at the flange hub
  • Smooth internal bore for better fluid flow
  • Available in carbon steel, stainless steel and alloy grades
