seamless pipe

Seamless pipe (including OCTG) are larger than the existing production capacity needs. Therefore, future emphasis should be placed on giving full play to the capacity of existing units to develop a high-strength grades, high against damage, high anti-corrosion of oil pipes, high-pressure boiler tubes and tube products such as cylinders. My country is the current steel market to optimize the product structure of the content. This is also to increase the competitiveness of their products at home and abroad, and expand market share in the key. In other words, improve the domestic steel pipe market competitiveness of enterprises and the WTO are added after the long-term task of domestic enterprises and the key to successful development.

1. Structural Seamless (GB/T8162-1999) are for general structure and the mechanical structure of the seamless tube.

2. With seamless fluid (GB/T8163-1999) are used for conveying water, oil, gas and other fluids generally seamless.

3. Low-medium pressure boiler seamless pipe (GB3087-1999) are used in the manufacture of various structural low and medium pressure boiler superheated steam pipes, boiling water pipes and superheated steam locomotive boiler tubes, opium pipe, tobacco pipe and a small brick arch effective high-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless.
4. High-pressure boiler seamless pipe (GB5310-1995) are used in the manufacture of high-pressure and over pressure water tube boiler heating surface with high-quality carbon steel, alloy steel and heat-resistant stainless steel seamless pipe.

5. Fertilizer equipment with high-pressure seamless pipe (GB6479-2000) are applicable to the work temperature -40 ~ 400 ?? working pressure of 10 ~ 30Ma chemical equipment and pipeline quality carbon structural steel and alloy steel seamless pipe.

6. Petroleum Cracking Seamless use (GB9948-88) are applicable to the oil refinery furnace tubes, heat exchangers and pipe seamless.

7. Geological Drilling Pipe (YB235-70) for the geological departments of the steel pipe used to drill cores, by end-use can be divided into the drill pipe, drill collar, core tubes, casing tubes, etc. and sediments.

8. Diamond core drilling with seamless pipe (GB3423-82) are used for diamond core drilling drill, core rod, seamless pipe casing.

9. Oil drilling pipe (YB528-65) are used for oil drilling inside the thickening or outside at both ends of seamless pipe thickening. Steel tube sub-car wire and wire the two cars, car wire connector useful links, not cars welded wire effective methods and tools for joint connection.

10. seamless pipe carbon steel seamless pipe (GB5213-85) is to create a ship I level pressure piping, ??grade pressure piping, boilers, and overheating of the carbon steel seamless pipe transparencies. Carbon steel seamless pipe wall temperature does not exceed 450 ?? alloy steel seamless pipe wall temperature exceeds the work of 450

11. Automobile axle casing with seamless pipe (GB3088-82) are manufacturing automobile axle casing and drive shaft Bridge shell effective quality carbon structural steel and alloy structural steel hot rolling seamless pipe.

12. Diesel engine with high pressure oil pipe (GB3093-86) is to create effective high-pressure diesel injection system of the cold-drawing seamless pipe.

13. Hydraulic and pneumatic cylinder with precision internal diameter seamless pipe (GB8713-88) are manufacturers of hydraulic and pneumatic cylinder used with precision internal diameter size of cold-drawing or cold-rolled seamless precision.

14. Cold-drawn or cold-rolled precision seamless pipe (GB3639-83) are used for the mechanical structure, hydraulic equipment, high dimensional accuracy and good surface finish cold-drawing or cold-rolled precision seamless. Selection of precision seamless tube manufacturing machinery, such as structural or hydraulic equipment, machining can greatly save time, improve material utilization, at the same time is conducive to improve product quality.

15. The structure of stainless steel seamless pipe (GB/T14975-1994) are widely used in chemical, petroleum, textile, medical, food, machinery and other industrial corrosion-resistant piping 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/T14976-1994) are used for transmission fluid made of hot-rolled stainless steel (extrusion, expansion) and cold-drawn (rolled) seamless.

17. Heterotypic seamless pipe are apart from other cross-section shape of an umbrella term seamless. By the pipe cross-section of different shapes and sizes can be divided into different types of seamless pipe wall thickness, etc. (code-named D), ranging from different types of seamless pipe wall thickness (code-named BD), variable-diameter seamless pipe heterotypic (code-named BJ).
