Seamless steel pipe can be classified into the following several kinds because of its different standards:
 
1. GB/T8162-1999 (the structure is made by seamless steel tube). It is mainly used for the general structure and the mechanical structure. It represents textures (brands) : carbon steel No 20 and No 45; Alloy steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, etc. 
 
2. GB/T8163-1999 (seamless steel tube is used for transmitting fluid). It is mainly used in engineering and large equipments in pipes conveying fluid. The standard materials (brands) are 20, Q345, etc. 
 
3. GB/T3087-1999 (low and intermediate pressure boiler is made by seamless steel tube). It is mainly used in industrial boiler and boiler of low intermediate pressure fluid pipe. Standard materials are Steel No 10, No 20. 
 
4. GB/T5310-1995 (high pressure boiler is made by seamless steel tube). It is mainly used for high voltage transmission fluid collection box and the pipeline in power plant and high temperature resistant nuclear power plant boiler. Standard materials are 20G, 12Cr1MoVG, 15CrMoG, etc. 
 
5. GB/T5312-1999 (ships are made by seamless steel tube of carbon steel and carbon manganese steel). It is mainly used for Marine boiler and overheating is used the class I and class II pressure tubes, etc. Standard materials are steel grade 360, 410, 460, etc. 
 
6. GB/T1479-2000 (seamless steel tube is used in high pressure chemical fertilizer equipments). It is mainly used for transmitting high-temperature and high-pressure liquid pipeline in fertilizer equipments. Standard materials are 20, 16Mn, 12CrMo, 12Cr2Mo, etc. 
 
7. GB/T9948-1988 (seamless steel tube is used in oil cracking). It is mainly used in the boiler in oil smelting plants, heat exchangers and pipes conveying fluid. Its representative materials are 20, 12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, etc.
