ASME SA213 T11 Tube




SA213 T11 Tube is a boiler class stainless steel tube that is made from different material grades. The tubes are used in heat exchangers, super heaters and in boilers. The qualities of the pipes make them available for the high temperature services. Steel India Co. is a manufacturer and supplier of these pipes in larger quantities. The T11 Tube Material consists of carbon, manganese, phosphorous, sulfur, silicon, nickel, chromium and molybdenum. The composition provides the material with high tensile strength, high yield strength and high Brinell numbers.

The T11 Boiler Tube can be hot finished or cold drawn. It could also be seamless, ERW, welded or fabricated. For the most part, the ASTM A213 T11 Tube is highly tolerant to elevated temperatures and is highly corrosion resistant. The ductility of the material also allows for machining operations such as the flanging, bending and others. Fusion welding is also available with T11 Tubes so that they could be used in industries such as the power generation industries and in the petrochemical industries. Our ASTM A213 T11 pipes are made up of best quality material and can perform better under high temperature and pressure conditions.
