11. Automobile axle pipe seamless tube (GB3088-82) is a manufacturing automobile axle tube and screw bridge shell shaft works of high quality carbon structural steel and alloy steel hot-rolled seamless pipe.
12. Diesel engine high-pressure tubing (GB3093-86) is a manufacturing diesel injection system high pressure pipe cold drawn seamless tube.
13. Hydraulic and pneumatic cylinder with precision inside diameter seamless pipe (GB8713-88) is a manufacturing hydraulic and pneumatic cylinder with diameter with precision cold drawn or cold rolled precision seamless tube.
14. Cold drawn or cold rolled precision seamless tube (GB3639-83) is used for mechanical structure, hydraulic equipment size precision and surface finish good cold drawn or cold rolled precision seamless tube. Choose precision seamless tube manufacturing mechanical structure or hydraulic equipment, etc., can greatly reduce machining time, improve material utilization, and at the same time to improve the quality of products.
15. Structure with stainless steel seamless tube (GB/T14975-2002) is widely used in chemical industry, petroleum, textile, medical, food, machinery, etc
16. Fluid delivery with stainless steel seamless tube (GB/T14976-2002) is used for the transmission fluid of the hot rolled stainless steel (squeeze, enlarge) and cold drawing (rolling) seamless tube.
17. Special seamless pipe is in addition to circular tube other than the cross section shape of the seamless pipe body. According to the steel pipe cross section shape and size can be divided into different, such as wall thickness deformed seamless pipe (code for D), unequal wall thickness deformed seamless tube (code for BD), variable diameter deformed seamless tube (code for BJ). Special seamless pipe is widely used in various structure, tools and machinery parts. And compared to the circular tube, the special pipe usually have large moment of inertia and section modulus, have bigger bending torsional ability, can greatly reduce the structural weight, save steel.
