Product Description
Definition and classification of steel pipes
Seamless steel tubes for low and medium pressure boilers: used to manufacture various low and medium pressure boilers. Superheated steam pipes. Boiling water pipes. Water wall tubes and superheated steam pipes for locomotive boilers. Big smoke pipe. small smoke pipes and arch brick pipes, etc. Hot-rolled or cold-rolled seamless steel pipes with high-quality carbon structural steel. It is mainly made of 10.20 steel, and in addition to ensuring the chemical composition and mechanical properties, it is necessary to do hydrostatic test and crimping. Flaring. Tests such as flattening. Hot rolled is delivered in hot rolled condition. Cold-rolled (dialed) is delivered in heat-treated condition.
High-pressure boiler steel pipes: mainly used to manufacture high-quality carbon structural steel for steam boiler pipes at high pressure and above pressure. Alloy structural steel and stainless heat-resistant steel seamless steel pipes. These boiler tubes work under high temperature and pressure. Oxidation and corrosion will also occur under the action of high-temperature flue gas and water vapor, so the steel pipe is required to have high long-lasting strength. High oxidation resistance, and has good microstructure stability, the steel grades are: high-quality carbon structural steel steel grades are 20G., 20MnG., 25MnG;
Alloy structural steel: 15MoG., 20MoG., 12CrMoG., 15CrMoG, 12Cr2MoG, 12CrMoVG., 12Cr3MoVSiTiB, etc.;
Rusty heat-resistant steel is commonly used: 1Cr18Ni9, 1Cr18Ni11Nb high-pressure boiler tubes in addition to ensuring chemical composition and mechanical properties, to do a hydrostatic test one by one, to do flaring. Flattening test. The steel pipes are delivered in heat-treated condition. In addition, the microstructure of the finished steel tube. Grain size. There are also certain requirements for the decarburization layer. seamless steel pipes for geological drilling and oil drilling control; In order to find out the structure of underground rock formations. Groundwater. Petroleum. Natural gas and mineral resources, using drilling rigs to drill wells. Petroleum.
