 Steel Pipe Co., Ltd. Liaocheng Tongyuan low and medium pressure boiler seamless steel pipe 
 Used in the manufacture of low and medium pressure boilers, superheated steam, boiling water pipe, water-wall tube and superheated steam locomotive boiler tubes, opium pipe, a small brick arch pipe and tubes. With high-quality hot-rolled or cold-rolled carbon structural steel (call) seamless steel pipe. No. 10,20 steel is mainly used, in addition to chemical composition and mechanical properties to ensure that outside pressure to do testing, crimping, flaring, flattening and other tests. To the state of delivery hot rolled, cold-rolled (allocated) to heat treatment delivery. 
 High-pressure boiler steel pipe 

 Mainly used to manufacture high-pressure and more pressure steam boiler tubes, etc. with high quality carbon steel, alloy steel and heat-resistant stainless steel seamless pipe, the boiler tubes often work in high temperatures and pressures, pipe tobacco at high temperature gas and water vapor under the effect of oxidation and corrosion will occur, thus requiring a durable steel with high strength, high oxidation resistance, and good organizational stability, the use of steel are: high-quality carbon structural steel with steel 20G, 20MnG, 25MnG; alloy steel steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB etc.; a rust resistant steel used 1Cr18Ni9, 1Cr18Ni11Nb Apart from ensuring high-pressure boiler tubes chemical composition and mechanical properties, to the root by pressure test done, to make flaring, flattening test. Steel with heat treatment delivery. In addition, the finished steel microstructure, grain size, there are certain requirements decarburization.
