ASME SA213 TP304 Stainless Steel Tubes For Superheater And High-Temperature And High-Pressure Pipe Fittings
1. Description
The difference between 304, 304H and 304L
In fact, according to the content of chromium and nickel, all of them are 304 stainless steel, with 18% chromium (CR) and 8% nickel (Ni), but the main difference lies in the carbon content.
SA213 TP304 is a very widely used stainless steel seamless pipe. The steel pipe has good bending and welding processing ability. It has good durability, high oxidation resistance and is sensitive to intergranular corrosion and stress corrosion. Because it is a variety of alloy components, it is very difficult to process hardness and cutting. This kind of seamless steel pipe is mainly used for manufacturing high temperature superheater, high temperature reheater, platen superheater high temperature section and large-scale power generation boiler high temperature and high pressure pipe fittings with large pressure parameters, close to critical or supercritical.
SA213 TP304 stainless steel seamless steel pipe can be offered below out looking and protection:
1) Spray marked on the surface.
2) threaded at both ends
3) chamfered at both ends
4) pipe cap protective cover at both ends
5) Plywooden box
Various export packaging methods can ensure the safe transportation of products. Our stainless steel seamless steel pipe products are of good quality and various materials meet the different needs of customers. The products are now sold well all over the world, and have won the praise and satisfaction of customers. They are widely used in many fields.
