The Usages of Seamless Steel Pipe

The time of issue:2014-5-8 10:19:51       Author:

Different standards of seamless steel tubes, which use different seamless steel giant multi-species, but also all have their different uses; different standards of seamless steel tubes each have their own purposes.

1 A structural seamless steel pipe (GB/T8162-1999) is used for seamless steel pipe for general structure and mechanical structure.
2 fluid seamless steel pipes (GB/T8163-1999) is generally seamless steel pipe used to transport water, oil, gas and other fluids.
3 low- pressure boiler seamless pipe (GB3087-1999) is 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, small pipe and brick arch effective high-quality carbon structural steel hot-rolled and cold drawn (rolled) seamless steel pipe.
4 high-pressure boiler seamless pipe (GB5310-1995) is used to manufacture high -quality carbon steel and more pressure water tube boiler heating surface with steel, alloy steel and heat-resistant stainless steel seamless pipe.

5 fertilizer equipment with high-pressure seamless steel pipe (GB6479-2000) is applied to the working temperature of -40 ~ 400 ℃, working pressure of high-quality carbon steel and alloy steel 10 ~ 30Ma of chemical equipment and seamless steel pipes.
6. Petroleum cracking (GB9948-88) is applied to the oil refinery furnace tubes, heat exchangers and pipe seamless steel pipe.
7. Geological drilling pipe (YB235-70) is for the geological department of the steel core drilling, use can be divided into the drill pipe, drill collars, core pipe, and casing and precipitation tubes.
8 diamond cores drilling seamless pipe (GB3423-82) is a drill, core rods for diamond core drilling seamless steel pipe casing.

9 oil drilling pipe (YB528-65) is used to thicken the oil drilling within or outside the thick ends of seamless steel tubes. Steel child thread, instead of two, threaded pipe connections, no thread methods and tools useful butt joint connection.
10 ships with carbon steel seamless pipe (GB5213-85) is manufactured Class I pressure vessels piping, Ⅱ grade pressure piping , boilers, and overheating of the carbon steel seamless pipe. Carbon steel seamless pipe wall temperature does not exceed 450 ℃, alloy steel seamless pipe wall temperature exceeds 450 ℃.
11 automobile axle casing seamless pipe (GB3088-82) is manufactured automobile axle casing and axle shaft tubes of high-quality carbon structural steel and alloy steel hot-rolled seamless steel tubes.
12 diesel engines with high-pressure pipe (GB3093-2002) is manufactured high-pressure diesel injection systems of cold drawn seamless steel tubes

13 hydraulic and pneumatic cylinders with precision diameter seamless steel pipe (GB8713-88) is a manufacturer of hydraulic and pneumatic cylinder with cold drawn or cold rolled precision seamless steel tubes with precision diameter size.
14 cold drawn or cold rolled precision seamless steel pipes (GB3639-2000) is used for high dimensional accuracy mechanical structure, hydraulic equipment and good surface finish cold drawn or cold rolled precision seamless steel tubes. Use precision seamless steel pipe manufacturing mechanical structure or hydraulic equipment, can greatly reduce machining time, improve material utilization, and help to improve product quality.
15. Structure with stainless steel seamless pipe (GB/T14975-2002) is widely used in hot-rolled chemical, petroleum, textile, medical, food, machinery and other industrial pipes and corrosion-resistant structural parts and components made of stainless steel (extrusion, expansion) and cold drawn (rolled) seamless steel pipe.
16. Fluid transport stainless steel seamless pipe (GB/T14976-2002) is a hot-rolled stainless steel conveying fluids (extrusion, expansion) and cold drawn (rolled) seamless steel pipe.
17. Shaped seamless steel pipe is in addition to other general term seamless pipe cross-sectional shape. Shaped seamless steel tubes are widely used in various structural parts, tools and machinery parts. And the tube compared Pipes generally have a greater moment of inertia and section modulus, flexural torsion greater capacity, can greatly reduce the structural weight, saving steel. The difference between GB/T9711, API SPEC 5L in, for example, API steel pipe use is for oil and natural gas industry, gas, water, oil transportation.
