SA213 T11 Tube is a specification and grade for low alloy boiler pipes. These pipes are made for use in boilers, heat exchangers and super heaters. Hi-tech Metal & Tubes is a manufacturer and supplier of these pipes in different shapes, sizes and dimensions.

ASME SA213 T11 Boiler Tube
T11 Tubes A213 T11

The T11 Boiler Tube has a very high temperature resistance. It has high durability and high tensile strength. The ASTM A213 T11 Tubes range from 6.35mm to 101.6mm in outer diameter. The ASTM A213 Gr T11 Tube Material consists of carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum in its composition. The addition of molybdenum in the A213 T11 Material composition makes the pipe stronger and corrosion resistant. There are seamless, hot rolled and cold drawn pipes in this specification. The pipes can also differ in their end types such as the plain ends, beveled ends, threaded ends and couplings. We manufacture and supply these pipes in standard length, double length and in cut length sizes. The SA213 T11 Seamless Alloy Tube ranges from NB 3/8 to NB 30 in nominal size and has different schedules ranging from schedule 20 to XXS and heavier. We take custom orders on the SA213 T11 Tubes as well. Please contact us with your requirements and we are ready to supply you.


DO YOU KNOW ??

ASME SA213 T11 Boiler Tube is ideally appropriate for chemical, petrochemicals, and other energy-related applications. It has characteristics of high corrosion resistance and can be utilized in a wide range of industrial segments.
