Maria Pipes and Tubes, based in Kuala Lumpur, Malaysia, has built a solid reputation as a reliable manufacturer and supplier of top-notch stainless steel piping solutions. Their Stainless Steel 310 and 310S EFW Pipes (Electric Fusion Welded) are expertly designed for high-temperature and corrosive settings. Thanks to cutting-edge EFW welding techniques, these pipes boast remarkable strength, consistency, and resistance to oxidation. Maria Pipes and Tubes caters to essential industries like petrochemical, power generation, furnace manufacturing, and chemical processing, providing products that adhere to strict international standards.
Stainless Steel 310 and 310S EFW Pipes are made up of 24–26% chromium and 19–22% nickel, which gives them outstanding resistance to oxidation, scaling, and high-temperature corrosion. The 310S variant features a lower carbon content (maximum 0.08%) compared to the 310, enhancing weldability and minimizing the risk of sensitization during the welding process. These pipes exhibit impressive mechanical properties, with tensile strength reaching up to 620 MPa and exceptional performance in service temperatures as high as 1100°C, making them perfect for maintaining structural integrity in extreme heat conditions.
