4. Seamless steel pipes for high-pressure boilers (GB5310-1995) are high-quality carbon steel, alloy steel and stainless heat-resistant steel seamless steel pipes for the heating surface of water-tube boilers with high pressure 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 a working temperature of -40 to 400°C and a working pressure of 10 to 30 Ma.
6. Seamless steel pipes for petroleum cracking (GB9948-88) 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 for core drilling by geological departments. They can be divided into drill pipes, drill collars, core pipes, casing pipes and sedimentation pipes according to their uses.
8. Seamless steel pipes for diamond core drilling (GB3423-82) are seamless steel pipes for drill pipes, core rods, and casings used for diamond core drilling.
9. Petroleum drilling pipe (YB528-65) is a seamless steel pipe used for thickening inside or outside at both ends of oil drilling. Steel pipes are divided into two types: wire and non-wired. Wired pipes are connected by joints, and non-wired pipes are connected with tool joints by butt welding.
