 Liaocheng Tongyuan Steel Pipe Co., Ltd. for low and medium pressure boiler seamless pipe 
 Used to manufacture a variety of low and medium pressure boiler, superheated steam pipes, boiling water tube, water wall tube and locomotive boilers, superheated steam pipe, opium pipe, small pipe and pipe arch brick. High-quality carbon structural steel hot-rolled or cold-rolled (allocated) seamless steel pipe. 10, 20 steel manufacturing, to do the hydrostatic test in addition to ensuring the chemical composition and mechanical properties, curling, flaring, flattening test. Hot-rolled, hot rolled condition, delivery, cold-rolled (allocated) to heat treatment delivery. 
 High-pressure boiler pipe 

 Mainly used to manufacture high pressure and over pressure steam boiler tubes with high-quality carbon structural steel, alloy steel and heat-resistant stainless steel seamless boiler tubes are often exposed to high temperatures and under high pressure pipe in the high-temperature smoke oxidation and corrosion will occur under the action of air and water vapor, therefore steel pipe has a high rupture strength, high oxidation resistance and have good organizational stability, using the steel: high-quality carbon structural steel in the steel 20G, 20MnG, 25MnG; alloy structural steel steel 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; rust heat-resisting steel commonly used 1Cr18Ni9 1Cr18Ni11Nb high-pressure boiler tubes to ensure that the chemical composition and mechanical properties, by root do the hydrostatic test for flaring, flattening test. Steel pipe to the heat treatment delivery. In addition, the finished steel microstructure, grain size, decarburized layer have certain requirements.
