Industrial thick-walled seamless steel pipe implementation standards
1. Structural seamless steel pipes (GB/T8162-2008) are seamless steel pipes used for general structures and mechanical structures.
2. Seamless steel pipes for fluid transportation (GB/T8163-2008) are general seamless steel pipes used to transport fluids such as water, oil, and gas.
3. Seamless steel pipes for low and medium-pressure boilers (GB3087 - 2008) are used to manufacture superheated steam pipes, billing 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-olld and cold-drawn (olled) seamless steel pipes for pipes.
4. Seamless steel pipes for high-pressure boilers (GB5310-2008) are high-quality carbon steel, alloy steel, and stainless heat-resistant steel seamless steel pipes used for the heating surfaces of water tube boilers with high pressures and above.
5. High-pressure seamless steel pipes for fertilizer equipment (GB6479-2000) are high-quality carbon structural steel and alloy steel seamless steel pipes suitable for chemical equipment and pipelines with working temperatures of -40~400°C and working pressures of 10~30Ma.
6. Seamless steel pipes for petroleum cracking (GB9948- 2006) are seamless steel 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 geological departments for core dilling. They can be divided into drill pipes, drill collars, core pipes, casings, and sedimentation pipes according to their uses.
8. Seamless steel pipe for diamond core drilling (GB3423-82) is a seamless steel pipe used for drill pipe, core rod, and casing for diamond core drilling.
9. An oil drilling pipe (YB528-65) is a seamless steel pipe with internal or external thickening at both ends used for oil drilling. There are two types of steel pipes:
wired and unthreaded. Threaded pipes are connected with joints, while non-threaded pipes are connected with tool joints by butt welding.
