High-performance stainless steel and nickel alloy seamless/welded pipes, tubes, and matching fittings for critical fluid systems.
Our seamless and welded pipes, tubes, and matching pipe fittings are engineered for critical applications. We specialize in high-grade Nickel Alloys and Special Stainless Steels, while supplying standard stainless steels for comprehensive industrial solutions. Custom sizing, precision cutting, and custom surface finishes are available upon request.
As a specialized global manufacturer and supplier of high-performance piping products, we offer an extensive portfolio of seamless & welded pipes, tubes, and matching pipe fittings. Our primary expertise lies in premium Nickel Alloys (Inconel, Incoloy, Hastelloy, Monel) and Special Stainless Steels (Duplex, Super Duplex, 254SMO, 904L), complemented by a complete line of standard austenitic stainless steels for versatile industrial applications.
Equipped with advanced production lines and stringent quality control systems, our monthly capacity exceeds 2,500 tons. We supply products certified under American (ASTM/ASME), European (EN/DIN), Japanese (JIS), Russian (GOST), and Chinese (GB) standards. All products are fully customizable in dimensions, wall thicknesses, and special surface conditions (AP, BA, Polished) to suit critical operating environments including offshore oil & gas, chemical processing, and marine engineering.
