Duplex Spools Manufacturer & Exporter in India

What is a Duplex Pipe Spool?

A Duplex Pipe Spool is a prefabricated piping assembly consisting of pipes, flanges, fittings and other components welded together as per project drawings. Duplex and Super Duplex stainless steels are widely used in spool fabrication due to their exceptional strength and resistance to chloride stress corrosion cracking.

Our spool fabrication process includes precision cutting, beveling, welding (GTAW, SMAW), NDT testing, dimensional inspection and surface finishing to meet international project standards.
