Seamless Tube
Seamless pipe is a long strip of steel with a hollow section and no seams around it.
Usage:
1. Structural seamless pipes (GB/T8162-2008) are seamless pipes used for general structures and mechanical structures.
2. Seamless pipes for fluid transportation (GB/T8163-2008) are general seamless pipes used to transport fluids such as water, oil, and gas.
3. Seamless pipes for low and medium pressure boilers (GB3087-2008) are used to manufacture superheated steam pipes, boiling water pipes for low and medium pressure boilers of various structures, and superheated steam pipes, large smoke pipes, small smoke pipes and arch bricks for locomotive boilers. High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless pipes for pipes.
4. Seamless pipes for high-pressure boilers (GB5310-2008) are high-quality carbon steel, alloy steel and stainless heat-resistant steel seamless pipes used for the heating surfaces of water tube boilers with high pressures and above.
5. High-pressure seamless pipes for fertilizer equipment (GB6479-2000) are high-quality carbon structural steel and alloy steel seamless pipes suitable for chemical equipment and pipelines with working temperatures of -40~400℃ and working pressures of 10~30Ma.
6. Seamless pipes for petroleum cracking (GB9948-2006) are seamless pipes suitable for furnace tubes, heat exchangers and pipelines in petroleum refineries.
7. Steel pipes for geological drilling (YB235-70) are steel pipes used by the geological department for core drilling. They can be divided into drill pipes, drill collars, core pipes, casings and sedimentation pipes according to their uses.
8. Seamless pipe for diamond core drilling (GB3423-82) is a seamless pipe used for drill pipe, core rod and casing for diamond core drilling.
9. Oil drilling pipe (YB528-65) is a seamless pipe with internal or external thickening at both ends for oil drilling.
10. Carbon steel seamless pipes for ships (GB5312-85)
11. Seamless pipes for automobile half-shaft casings (GB3088-82) are high-quality carbon structural steel and alloy structural steel hot-rolled seamless pipes used for manufacturing automobile half-shaft casings and drive axle housing shaft tubes.
12. High-pressure oil pipe for diesel engine (GB3093-86) is a cold-drawn seamless pipe used to manufacture high-pressure pipes for diesel engine injection systems.
13. Precision inner diameter seamless pipe for hydraulic and pneumatic cylinders (GB8713-88) is a cold-drawn or cold-rolled precision seamless pipe with precise inner diameter for manufacturing hydraulic and pneumatic cylinders.
14. Cold-drawn or cold-rolled precision seamless pipe (GB3639-83) is a cold-drawn or cold-rolled precision seamless pipe with high dimensional accuracy and good surface finish used in mechanical structures and hydraulic equipment. Precision seamless tubes are used to manufacture mechanical structures or hydraulic equipment, etc.
15. Stainless steel seamless pipes for structural use (GB/T14975-2002) are hot-rolled ( Extruded, expanded) and cold drawn (rolled) seamless tubes.
16. Stainless steel seamless pipes for fluid transportation (GB/T14976-2002) are hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless pipes made of stainless steel used to transport fluids.
17. Special-shaped seamless pipes are the general term for seamless pipes with other cross-sectional shapes except round pipes. According to the different cross-sectional shapes and sizes of steel pipes, they can be divided into special-shaped seamless pipes with equal wall thickness (code-named D), special-shaped seamless pipes with unequal wall thickness (code-named BD), and variable-diameter special-shaped seamless pipes (code-named BJ). Special-shaped seamless pipes are widely used in various structural parts, tools and mechanical parts.
18. Seamless steel pipes for low-temperature pipelines (GB/T18984-2003) are seamless steel pipes used for -45℃~-195℃ low-temperature pressure vessel pipes and low-temperature heat exchanger pipes.
