7.Geological drilling steel (YB235-70) is for the use of the geological department of the steel core drilling, can be divided by use of drill pipe, drill collars, cores, sleeves and precipitation tubes. 

8.Diamond core drilling Seamless (GB3423-82) for diamond core drilling drill, core rods, seamless steel casing. 

9.Oil drilling pipe (YB528-65) is used to thicken the oil drilling within or outside the thick ends of the seamless steel tubes. Steel wire and non-sub-car wire two car, car connector wire useful links, no threading methods and tools useful butt joint connection. 10.The ship carbon steel seamless pipe (GB5213-85) is the manufacture of pressure vessels piping grade I, II grade pressure piping, boilers and Super heater carbon steel seamless pipe. Carbon steel seamless pipe wall temperature does not exceed 450 Degree Centigrade, alloy steel seamless steel pipe wall temperatures in excess of 450 Degree Centigrade. 

11.Automobile axle casing seamless pipe (GB3088-82) is the manufacture of automobile axle tube and axle shaft axle useful high-quality carbon structural steel and alloy steel hot-rolled seamless steel tubes. 

12.Diesel high pressure oil pipe (GB3093-2002) is to create high-pressure diesel injection system useful in the cold drawn seamless steel tubes. 

13.Hydraulic and pneumatic cylinder seamless steel with precision internal diameter (GB8713-88) is a manufacturer of hydraulic and pneumatic cylinder with a diameter size with precision cold drawn or cold rolled precision seamless steel tubes. 

14.Drawn or rolled precision seamless pipe (GB3639-2000) is used for mechanical structure, hydraulic equipment, high dimensional accuracy and surface finish of a good cold-drawn or cold rolled precision seamless steel tubes. Use precision seamless steel pipe manufacturing equipment, mechanical or hydraulic structure can be significant savings in machining time while improving material utilization, and help to improve product quality. 

15.Stainless steel seamless tubes (GB/T14975-2002) is widely used in chemical, petroleum, textile, medical, food, machinery and other industrial corrosion resistant pipes and structural parts and components made of hot rolled stainless steel ( extrusion, expansion) and cold drawn (rolled) seamless. 

16.Fluid transport stainless steel seamless pipe (GB/T14976-2002) is used for the transmission fluid made of hot-rolled stainless steel (extrusion, expansion) and cold drawn (rolled) seamless. 

17.Shaped seamless steel tube is in addition to other than the general cross-section shape of seamless steel tubes. By the different shape and size of pipe section can be divided into such shaped seamless steel pipe wall thickness (code-named D), ranging from shaped seamless steel pipe wall thickness (code-named BD), variable diameter shaped seamless steel pipe (code-named BJ). Shaped seamless steel pipe used in a variety of structural parts, tools and mechanical parts. And the tube compared to special section tube generally larger moment of inertia and section modulus, a larger bending and distorting ability, can significantly reduce the structural weight, saving steel.
