Grafton Pipe Fittings is a renowned manufacturer and global supplier of high-performance Stainless Steel Pipes & Tubes crafted for industrial excellence and reliability. Our stainless steel products are engineered using the highest grade materials, including the widely used ASTM A312 and ASTM A213 specifications. With unmatched corrosion resistance, tensile strength, and thermal endurance, our pipes and tubes are ideal for use in diverse applications such as petrochemical industries, power plants, heat exchangers, construction, and marine environments.

The ASTM A312 standard defines seamless and welded austenitic stainless steel pipes, suitable for high-temperature and general corrosive service. Our pipes are primarily produced using UNS S30400 (Grade 304), one of the most versatile and commonly used stainless steels globally. This grade offers excellent welding and forming characteristics, and its resistance to oxidation and moderate corrosion makes it a preferred choice in food processing, architectural structures, and water treatment facilities.

For more specialized applications, Grafton Pipe Fittings also supplies stainless steel tubes in accordance with ASTM A213 specifications, featuring grades such as UNS S31600 (316) and UNS S32100 (321). These materials are known for their improved resistance to chlorides, acids, and high-temperature exposure. Our seamless stainless steel tubes are precision-made with tight tolerances, excellent surface finish, and superior dimensional accuracy.

All Stainless Steel Pipes & Tubes from Grafton Pipe Fittings conform to international standards such as ASME, DIN, EN, and JIS. They are available in various shapes—round, square, and rectangular—and sizes ranging from 1/8" to 24" in diameter, with wall thicknesses customized to meet specific project requirements. Each product is tested for hydrostatic pressure, pitting resistance, and chemical composition to guarantee performance and quality.
