11. Seamless steel tubes for automotive half-axle casing (GB3088-82) are high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel tubes for the manufacture of automobile axle bushings and drive axle housings.
12. The high-pressure fuel pipe for diesel engines (GB3093-2002) is a cold-drawn seamless steel pipe for the high pressure pipes used in the manufacture of diesel injection systems.
13. Precision inner diameter seamless steel tubes for hydraulic and pneumatic cylinders (GB8713-88) are precision-drawn or cold-rolled precision seamless steel tubes with precision inner diameter dimensions for the manufacture of hydraulic and pneumatic cylinders.
14. Cold-drawn or cold-rolled precision seamless steel tubes (GB3639-2000) are cold-drawn or cold-rolled precision seamless steel tubes for mechanical structures and hydraulic equipment with high dimensional accuracy and good surface finish.
The use of precision seamless steel pipe manufacturing machinery structures or hydraulic equipment, etc., can greatly reduce the mechanical processing time, improve the material utilization, and help improve product quality.
15. Structural stainless steel seamless pipes (GB/T14975-2002) are hot-rolled stainless steels that are widely used in corrosion-resistant pipes and structural parts and components in the chemical, petroleum, textile, medical, food, and machinery industries. Squeeze, expand) and cold drawn (rolled) seamless steel tubes.
16. Stainless Steel Seamless Pipe for Fluid Conveyance (GB/T14976-2002) is a hot rolled (extruded, expanded) and cold drawn (rolled) seamless steel pipe made of stainless steel for conveying fluids.
17. Shaped seamless steel tubes are the general term for seamless steel tubes of other cross-sectional shapes than round tubes. According to the different shapes and sizes of steel pipe sections, they can be divided into equal-wall thickness special-shaped seamless steel pipes (code D), unequal wall thickness profiled seamless steel pipes (codenamed BD) and variable-diameter special-shaped seamless steel pipes (coded as BJ). Shaped seamless steel tubes are widely used in various structural parts, tools and mechanical parts. Compared with round tubes, shaped tubes generally have larger moments of inertia and section modulus, and have greater resistance to bending and torsion, which can greatly reduce the structural weight and save steel.
