What are the implementation standards for cold drawn pipes?
2. Cold drawn pipes for fluid transportation (GB/T8163-2008) are general seamless steel pipes used to transport fluids such as water, oil, and gas.
3. Cold drawn pipes for low and medium pressure boilers (GB3087-2008) are high-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipes used to manufacture superheated steam pipes, boiling water pipes for low and medium-pressure boilers of various structures, superheated steam pipes and arch brick pipes for locomotive boilers.
4. Cold drawn tubes 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 surface of water tube boilers with high pressures and above.
5. High-pressure cold-drawn 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℃ and working pressures of 10~30Ma.
6. Cold drawn tubes for petroleum cracking (GB9948-2006) are seamless steel tubes suitable for furnace tubes, heat exchangers and pipelines in petroleum refineries.
7. Cold drawn pipe (YB235-70) for geological drilling is a steel pipe used by the geological department for core drilling. It can be divided into drill pipe, drill collar, core pipe, casing and sedimentation pipe according to its purpose.
8. Cold drawn 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. Oil drilling pipe (YB528-65) is a seamless steel pipe with internal or external thickening at both ends 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.
10. Carbon steel cold-drawn pipes for ships (GB5213-85) are carbon steel seamless steel pipes used in manufacturing ship Class I pressure-resistant piping systems, Class II pressure-resistant piping systems, boilers and superheaters. The working temperature of the carbon steel seamless steel pipe wall does not exceed 450°C, and the working temperature of the alloy steel seamless steel pipe wall exceeds 450°C.
11. Cold-drawn tubes for automobile half-shaft casings (GB3088-82) are high-quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipes used for manufacturing automobile half-shaft casings and drive axle housing shaft tubes.
12. High-pressure oil pipe for diesel engines (GB3093-2002) is a cold-drawn seamless steel pipe used to manufacture high-pressure pipes for diesel engine injection systems.
13. Precision inner diameter cold-drawn pipe for hydraulic and pneumatic cylinders (GB8713-88) is a cold-drawn or cold-rolled precision seamless steel pipe with precise inner diameter for manufacturing hydraulic and pneumatic cylinders.
14. Cold-drawn or cold-rolled precision seamless steel pipe (GB3639-2000) is a cold-drawn or cold-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish used in mechanical structures and hydraulic equipment. The use of precision seamless steel pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and at the same time help improve product quality.
15. Stainless steel cold-drawn pipes for structural use (GB/T14975-2002) are hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless steel pipes made of stainless steel that are widely used in corrosion-resistant pipes and structural parts and components in chemical, petroleum, textile, medical, food, machinery and other industries.
16. Stainless steel seamless steel pipes for fluid transportation (GB/T14976-2002) are hot-rolled (extruded, expanded) and cold-drawn (rolled) seamless steel pipes made of stainless steel used to transport fluids.
