TP347H-stabilized elements (such as titanium or niobium) austenitic stainless steel industrial welded pipes

TP347H Stainless steel welded pipe is a special austenitic stainless steel material, it belongs to the thermal strength steel series, with good thermal stability and intercrystalline corrosion resistance. This material is particularly suitable for use in high temperatures, such as in boiler superheater tubes, reheater tubes, steam pipes, and petrochemical heat exchangers. TP347H Good welding performance of stainless steel welded pipe, which allows it to maintain material integrity and corrosion resistance during the manufacturing process.

    TP347H Features of stainless steel welded pipe include:


    Thermal strength: it can still maintain good mechanical properties at high temperature.
    Resistance to intercrystalline corrosion: by adding niobium (Nb) as a stabilizer, intercrystalline corrosion is effectively prevented.
    Corrosion resistance: it shows good corrosion resistance in alkaline, seawater and various acidic environments.
    Welding performance: suitable for welding process, can ensure the quality and integrity of the weld.
    In terms of application, TP347H stainless steel welded pipe is widely used in the generator set, boiler superheater tube, reheater tube, steam pipe and petrochemical heat exchanger and other high temperature and high pressure environment. In addition, it is suitable for antioxidant situations, with its allowable antioxidant temperature up to 750℃.
    When selecting and using TP347H stainless steel welded pipes, the material meets the corresponding international standards, such as ASTM A213 and ASTM A312, which specify the chemical composition, mechanical properties and manufacturing process requirements. In addition, due to its application characteristics at high temperature, it is also very important to choose suitable welding methods and welding materials to ensure the quality of the weld seam and the durability of the overall structure.
