Product Details

           Cold rolled seamless pipe is used for mechanical structure, hydraulic equipment size accuracy and surface smoothness of good cold drawn or cold rolled precision seamless steel pipe.Cold rolling (dial) seamless tube in addition to the general steel pipe, low and medium pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, other steel pipes, but also including carbon thin wall steel pipe, alloy thin wall steel pipe, stainless steel pipe, non-rust thin wall steel pipe, shaped steel pipe.The outer diameter of hot rolled seamless pipe is generally more than 32mm, wall thickness 2.5-75mm, cold rolled seamless steel pipe diameter can be up to 6mm, wall thickness can be up to 0.25mm, thin wall diameter can be up to 5mm, wall thickness is less than 0.25mm, cold rolling than hot rolling size accuracy.

Cold drawing process

            Cold rolling refers to the process of cold drawing, cold bending, cold drawing and other cold processing of steel plate or strip into various types of steel at room temperature.

Cold rolled seamless pipe Application

           1. Seamless tube for structure (GB/ t8162-1999) is a seamless tube for general structure and mechanical structure.

           2. Seamless tube for fluid transportation (GB/ t8163-1999) is a general seamless tube used for transporting water, oil, gas and other fluids.

          3. Seamless tube for low and medium pressure boiler (gb3087-1999) is a kind of high quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless tube used for manufacturing superheated steam tube for low and medium pressure boiler, boiling water tube and superheated steam tube for locomotive boiler, large smoke tube, small smoke tube and arch brick pipe.

         4. Seamless tube for high pressure boiler (gb5310-1995) is used for manufacturing high pressure and above water tube boiler heating surface of high-quality carbon steel, alloy steel and stainless heat resistant steel seamless tube.

          5. High pressure seamless tube for fertilizer equipment (gb6479-2000) is suitable for high quality carbon structural steel and alloy steel seamless tube for chemical equipment and pipelines with working temperature of -40~400℃ and working pressure of 10~30Ma.

           6. Seamless pipe for petroleum cracking (gb9948-88) is the seamless pipe for furnace pipe, heat exchanger and pipeline in petroleum refinery.

          7. Steel pipe for geological drilling (yb235-70) is a steel pipe for core drilling by geological departments. It can be divided into drill pipe, drill collar, core pipe, casing pipe and precipitation pipe.

8Seamless pipe for diamond core drilling (gb3423-82) is the seamless pipe for drill pipe, core pipe and casing for diamond core drilling.

           9. Oil drilling pipe (yb528-65) is a seamless pipe used for internal or external thickening of both ends of oil drilling.Steel pipe can be divided into wire and wire two, wire pipe joint, wire pipe butt welding method and tool joint.

         10. Ship with carbon steel seamless tube (GB5213-85) is the manufacturing of ship class I pressure piping, pressure piping Ⅱ, boiler and overheating for carbon steel seamless tube.The working temperature of seamless tube wall of carbon steel shall not exceed 450℃, while that of seamless tube wall of alloy steel shall exceed 450℃.

         11.Automobile semi-axle sleeve tube seamless tube is the manufacture of automobile semi-axle sleeve tube and drive axle axle axle tube of high quality carbon structure steel and alloy structure steel hot rolled seamless tube.

         12. High pressure oil pipe for diesel engine (gb3093-86) is a cold drawn seamless pipe used for high pressure pipe used in diesel engine injection system.

        13. Precision inner diameter seamless tube for hydraulic and pneumatic cylinders (gb8713-88) is a precision cold drawing or cold rolling seamless tube with precision inner diameter size for the manufacture of hydraulic and pneumatic cylinders.

         14. Cold drawing or cold rolling precision seamless tube (gb3639-83) is used for mechanical structure, hydraulic equipment with high dimensional accuracy and good surface finish.The selection of precision seamless tube manufacturing mechanical structure or hydraulic equipment, can greatly save machining time, improve material utilization, and improve product quality.

         15. The structure of stainless steel seamless tube (GB/ t14975-1994) is widely used in chemical, petroleum, textile, medical, food, machinery and other industries corrosion resistant pipeline and structural parts and parts of stainless steel made of hot rolling (extrusion, expansion) and cold drawing (rolling) seamless tube.

         16. Stainless steel seamless tube for fluid transport (GB/ t14976-1994) is a hot rolled (extruded, expanded) and cold drawn (rolled) seamless tube made of stainless steel for fluid transport.

         17. Shaped seamless pipe is in addition to the circular pipe other section shape of seamless pipe.According to the different shapes and sizes of steel tube sections, it can be divided into isometric shaped seamless pipes (code name: D), isometric seamless pipes with different wall thickness (code name: BD) and isometric shaped seamless pipes with variable diameter (code name: BJ).Shaped seamless pipe is widely used in various structural parts, tools and mechanical parts.Compared with the circular tube, the special-shaped tube generally has a larger moment of inertia and section modulus, has a larger bending and torsion resistance, can greatly reduce the weight of the structure, save steel.
