    DIN 2391 ST52 NBK Carbon Steel Seamless Pipes

    DIN 2391 ST52 Pipes are low carbon or mild carbon steel pipes. There are welded and seamless pipe types in this specification and grade. These are cost effective pipes with good finish. Shanghai ShengQiu is a leading manufacturer and supplier of the DIN 2391 ST52 seamless steel tubes and pipes. 



    The pipe ending differs for DIN 2391 ST52 Carbon Steel Seamless Pipes such as beveled, plain or threaded types. The pipes are used in high precision applications such as oil and gas, boiler, heat exchanger and others. The DIN 2391 ST52 High Precision Seamless Tube is highly thermally conductive and transfers heat faster than the austenitic steels. This feature allows the pipes to be welded with high temperature welding methods without causing cracks. The use of filler materials and preheating depend on the welding procedure and the application requirement. The DIN 2391 ST52 Carbon Steel Pipe last longer and has high ductility. The different finishes such as polished, annealed and pickles, bright annealed and MF are also available. Please feel free to contact us for more information on the pipes as we are a leading ST 52 Pipe Supplier.
