Specific applications are as follows
1. Seamless steel pipe for structure (GB/T8162-2008) is a seamless steel pipe used for general structure and mechanical structure.
2. Seamless steel pipe for fluid transportation (GB/T12771-2008) is a general seamless steel pipe used to transport water, oil, gas and other fluids.
3. Seamless steel pipes for low and medium pressure boilers (GB/T3087-2008) are used to manufacture superheated steam pipes, boiling water pipes for low and medium pressure boilers of various structures, and superheated steam pipes, large smoke pipes, and small smoke pipes for locomotive boilers. High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipes for arch brick pipes.
4. Seamless steel pipes for high-pressure boilers (GB5310-2008) are high-quality carbon steel, alloy steel and stainless heat-resistant steel seamless steel pipes for the heating surface of water-tube boilers with high pressure and above.
5. High-pressure seamless steel pipes for fertilizer equipment (GB6479-2000) are high-quality carbon structural steel and alloy steel seamless steel pipes suitable for chemical equipment and pipelines with a working temperature of -40 to 400°C and a working pressure of 10 to 30 Ma.
6. Seamless steel pipes for petroleum cracking (GB9948-2006) are seamless steel pipes suitable for furnace tubes, heat exchangers and pipelines in petroleum refineries.
7. Steel pipes for geological drilling (YB235-70) are steel pipes used for core drilling by geological departments. They can be divided into drill pipes, drill collars, core pipes, casing pipes and sedimentation pipes according to their uses.
8. Seamless steel pipes for diamond core drilling (GB/T3423-82) are seamless steel pipes for drill pipes, core rods, and casings used for diamond core drilling.
