Boiling water tubes and locomotive boilers with high quality carbon structural steel hot rolled and cold drawn (rolled) seamless steel tubes, equipped with superheated steam tubes, large smoke tubes, small smoke tubes and arch brick tubes. Representative materials are 10, 20 steel. 4. GB5310-1995 (seamless steel pipe for high pressure boiler) is a high quality carbon steel, alloy steel and stainless steel heat resistant seamless steel pipe for high pressure and above water tube boiler heating surface. The representative materials are 20G, 12Cr1MoVG, 15CrMoG, etc.5. GB1479-2000 (seamless steel pipe for high-pressure fertilizer equipment) is a high-quality carbon structural steel and alloy steel seamless steel pipe for chemical equipment and pipelines with working temperature of -40~400℃ and working pressure of 10~30Ma. The representative materials are 20, 16Mn, 12CrMo GB9948-1988 (seamless steel pipe for petroleum cracking). Mainly used in petroleum refinery boilers, heat exchangers and their transport fluid piping. Its representative materials are 20, 12CrMo, 1Cr5Mo and 1Cr19Ni11Nb, etc.7. Geological drilling steel pipe (YB235-70) is a steel pipe used for core drilling in the geological department. It can be divided into drill pipe, drill collar, coring pipe, casing and sediment pipe according to the usage.8. Seamless Steel Pipe for Diamond Coring Drilling (GB3423-82) is a seamless steel pipe for diamond coring drill pipe, coring rod and casing.9. Oil Drill Pipe (YB528-65) is a seamless steel pipe thickened inside and outside at both ends of oil drill pipe. The steel pipe is divided into two types: threaded and non-threaded. Threaded pipes are connected with joints, and non-threaded pipes are connected with tool joints by butt welding.10. GB5312-1999 (seamless carbon steel and carbon manganese steel pipes for marine use) is a seamless carbon steel pipe used for the manufacture of primary pressure-resistant piping systems, secondary pressure-resistant piping systems, boilers and superheaters. The working temperature of carbon steel seamless steel pipe wall does not exceed 450℃, and the working temperature of alloy steel seamless steel pipe wall exceeds 450℃. Representative materials are 360, 410, 460 and other steel grades.11. Seamless steel pipe for automobile axle housing (GB3088-82) is a high quality carbon structural steel and alloy structural steel hot-rolled seamless steel pipe used in the manufacture of automobile axle housing and drive axle housing.12. Diesel engine high-pressure oil pipe (GB3093-86) is a cold-drawn seamless steel pipe used to manufacture high-pressure pipes for diesel engine injection systems.13. GB8713-88 "Precision Inner Diameter Seamless Steel Pipe for Hydraulic Cylinder" is a cold-drawn or cold-rolled precision seamless steel pipe for manufacturing hydraulic cylinders. 14. Cold-drawn or cold-rolled precision seamless steel pipe (GB3639-83) is a cold-drawn or hot-rolled precision seamless steel pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. Using precision seamless steel tubes to manufacture mechanical structures or hydraulic equipment can greatly save processing time, improve material utilization and help improve product quality.15.
