Release date:
2022-10-13
High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel tubes are used for boiler water pipes and locomotive boilers, equipped with superheated steam tubes, large smoke tubes, small smoke tubes, and arch-shaped brick tubes. Representative materials include 10 and 20 steel. Additionally, GB5310-1995 (Seamless Steel Tubes for High-Pressure Boilers) specifies high-grade carbon, alloy, and stainless steel heat-resistant seamless steel tubes suitable for the heating surfaces of high-pressure and above water-tube boilers.
Boiling water tubes and locomotive boilers utilize high-quality carbon structural steel in hot-rolled and cold-drawn (rolled) seamless steel pipes, equipped with superheated steam pipes, large smoke tubes, small smoke tubes, and arch brick tubes. Representative materials include 10 and 20 steel grades. 4. GB5310-1995 (Seamless Steel Tubes for High-Pressure Boilers) specifies high-quality heat-resistant seamless steel tubes—made from carbon steel, alloy steel, and stainless steel—for the heating surfaces of high-pressure and above water-tube boilers. Notable materials include 20G, 12Cr1MoVG, and 15CrMoG, among others. 5. GB1479-2000 (Seamless Steel Tubes for High-Pressure Fertilizer Equipment) is designed for chemical equipment and pipelines, using premium carbon structural steel and alloy steel seamless tubes capable of operating at temperatures ranging from -40°C to 400°C and pressures between 10 and 30 MPa. Representative materials encompass 20, 16Mn, 12CrMo, and 12Cr2Mo, among others. 6. GB9948-1988 (Seamless Steel Tubes for Oil Cracking Applications) is primarily used in boilers, heat exchangers, and fluid-conveying pipelines within petroleum refineries. Its representative materials include 20, 12CrMo, 1Cr5Mo, and 1Cr19Ni11Nb, among others. 7. Geological drilling steel tubes (YB235-70) are specifically tailored for core drilling operations conducted by geological departments. These tubes are categorized based on their applications into drill rods, drill collars, core barrels, casing pipes, and settling tubes. 8. "Seamless Steel Tubes for Diamond Core Drilling" (GB3423-82) are precision-engineered seamless steel tubes intended for diamond core drill rods, core barrels, and casing pipes. 9. Petroleum drill pipes (YB528-65) are seamless steel tubes with thickened ends—both internally and externally—designed for use as drill pipes in oil exploration. These tubes come in two main types: threaded and non-threaded. Threaded tubes connect via specialized joints, while non-threaded tubes are joined to tool connections through butt welding. 10. GB5312-1999 (Seamless Carbon and Carbon-Manganese Steel Tubes for Marine Use) provides high-quality carbon steel seamless tubes suitable for manufacturing primary and secondary pressure piping systems, boilers, and superheaters. Carbon steel tubes can withstand operational temperatures up to 450°C, whereas alloy steel tubes are engineered for even higher temperature applications exceeding 450°C. Representative steel grades include 360, 410, and 460, among others. 11. Seamless steel tubes for automotive axle housings (GB3088-82) are precision-crafted hot-rolled carbon and alloy structural steel tubes, ideal for producing both axle housings and drive axle casings in vehicles. 12. High-pressure fuel lines for diesel engines (GB3093-86) are cold-drawn seamless steel tubes meticulously manufactured to serve as critical components in diesel engine fuel injection systems. 13. GB8713-88, "Precision Inner Diameter Seamless Steel Tubes for Hydraulic Cylinders," refers to cold-drawn or cold-rolled precision seamless steel tubes specifically engineered for manufacturing hydraulic cylinders. 14. Precision cold-drawn or cold-rolled seamless steel tubes (GB3639-83) are highly accurate in dimensions and boast exceptional surface finishes, making them ideal for mechanical structures and hydraulic systems. Utilizing these precision tubes significantly reduces machining time, enhances material efficiency, and ultimately improves product quality. 15. "Seamless Stainless Steel Tubes for Structural Applications" (GB/T14975-1994) encompasses both hot-rolled (extruded or expanded) and cold-drawn (rolled) seamless steel tubes. Our company stands as a professional manufacturer of stainless steel tubes, consistently supplying a wide range of specifications—including stainless steel pipes, plates, bars, coils, and specialized products like 304 stainless steel tubes, 316L stainless steel tubes, precision stainless steel tubes, 321 stainless steel tubes, 310S stainless steel tubes, 309S stainless steel tubes, 304L stainless steel tubes, 310S stainless steel seamless tubes, 316 stainless steel seamless tubes, and 316L stainless steel seamless tubes. We also offer 310S stainless steel square tubes, 309S stainless steel square tubes, custom-shaped stainless steel profiles, flat stainless steel bars, stainless steel angles, and round stainless steel bars. In addition, we act as agents for renowned steel brands such as TISCO, Baosteel, Shanggang, Zhangpu, Dagang, Jiugang, and Lianzhong, alongside distributing various imported stainless steel grades. Furthermore, our tungsten steel products have become key suppliers to leading domestic companies specializing in large-scale mold development, defense industries, machinery fabrication facilities, and automotive manufacturing sectors.
