Irfan Pipes and Tubes, located in Istanbul, Turkey, stands out as a leading manufacturer and supplier of **Stainless Steel 310 and 310S EFW Pipes**. They provide top-notch piping solutions for industries that need strength and heat resistance. These Electric Fusion Welded (EFW) pipes are crafted using cutting-edge techniques, ensuring they are precise, high-performing, and durable even in tough conditions. Renowned for their exceptional resistance to oxidation, corrosion, and high temperatures, 310/310S EFW pipes are relied upon globally in refineries, chemical plants, furnaces, and power generation sectors. Irfan Pipes and Tubes is committed to delivering products that meet international quality standards for a variety of industrial applications.
Stainless Steel 310 and 310S EFW Pipes are high-alloy austenitic steels containing 24–26% chromium and 19–22% nickel, which gives them remarkable resistance to oxidation and scaling at high temperatures. The 310S version has a lower carbon content, which helps minimize carbide precipitation and improves weldability. These pipes boast high tensile and yield strength, excellent toughness, and structural stability even when subjected to thermal cycling. Mechanically, they resist creep and stress rupture at elevated temperatures, making them perfect for long-term high-heat applications. The EFW process guarantees strong welds, uniformity, and durability in heavy-duty piping systems.
