7. Steel pipes for geological drilling (YB235-70) are steel pipes used by the Ministry of Geology for core drilling. They can be divided into drill pipes, drill collars, core pipes, casing pipes and sedimentation pipes according to their purposes.

8. Seamless steel pipes for diamond core drilling (GB3423-82) are seamless steel pipes for drill pipes, core rods, and casings used for diamond core drilling.

9. Petroleum drilling pipe (YB528-65) is a seamless steel pipe used for thickening inside or outside at both ends of oil drilling. There are two types of steel pipes: wire and non-wired. Wired pipes are connected by joints, and non-wired pipes are connected with tool joints by butt welding.

10. Carbon steel seamless steel pipes for ships (GB5213-85) are carbon steel seamless steel pipes used in the manufacture of Class I pressure piping systems, Class II pressure piping systems, boilers and superheaters. The working temperature of the carbon steel seamless steel pipe wall does not exceed 450"C, and the working temperature of the alloy steel seamless steel pipe wall exceeds 450C.

11. Seamless steel tubes for automobile axle sleeves (GB3088-82) are high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel tubes for the manufacture of automobile axle sleeves and drive axle axle tubes.

12. High-pressure oil pipes for diesel engines (GB3093-86) are cold-drawn seamless steel pipes used to manufacture high-pressure pipes for diesel engine injection systems.

13. Precision inner diameter seamless steel pipes for hydraulic and pneumatic cylinders (GB8713-88) are cold-drawn or cold-rolled precision seamless steel pipes with precise inner diameters for the manufacture of hydraulic and pneumatic cylinders.

14. Cold-drawn or cold-rolled precision seamless steel pipe (GB3639-83) is a cold-drawn or cold-rolled precision seamless steel pipe used for mechanical structures and hydraulic equipment with high dimensional accuracy and good surface finish The use of precision seamless steel pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining man-hours, increase material utilization, and at the same time help improve product quality.

15.Stainless steel seamless steel pipes for structural use (GB/T14975-1994) are hot rolled ( Extruded, expanded) and cold drawn (rolled) seamless steel tubes.

16. Stainless steel seamless steel pipes for fluid transportation (GB/T14976-1994) are hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless steel pipes made of stainless steel for fluid transportation.

17. Special-shaped seamless steel pipe is a general term for seamless steel pipes with cross-sectional shapes other than round pipes. According to the different shape and size of the steel pipe section, it can be divided into equal-thickness special-shaped seamless steel pipe (code D), unequal-thickness special-shaped seamless steel pipe (code BD), variable diameter special-shaped seamless steel pipe (code BJ). Special-shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with round pipes, special-shaped pipes generally have larger moments of inertia and section modulus, and have greater bending and torsion resistance, which can greatly reduce structural weight and save steel.
