Seamless steel tubes are made by piercing a solid round steel billet, resulting in pipes without any visible welds on the surface. Depending on the production method, seamless steel tubes can be categorized into...Hot-rolled Seamless Steel Pipe、Cold Rolled Seamless Steel Pipe、Cold Drawn Seamless Steel PipeExtruded seamless steel tubes, jacking pipes, etc. Seamless steel tubes are divided into circular and non-circular types based on their cross-sectional shapes. Non-circular tubes come in various complex shapes such as square, elliptical, triangular, hexagonal, pumpkin-shaped, star-shaped, and winged pipes. Diameters range up to 900mm and down to 4mm. Depending on their applications, they are...Thick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel tubes are primarily used for oilGeological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors.

General-purpose items (used for water and gas pipelines, structural components, and mechanical parts) and specialized items (used for boilers, geological exploration, bearings, acid resistance, etc.) are divided into two categories based on their applications.
1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolled, high yield, primarily used for pipes or structural parts conveying fluids.
2. Offer three categories of supplies based on different applications:
Available by chemical composition and mechanical properties.
b. Supplied by mechanical properties;
c. As perHydrostatic TestSupply. Steel pipes supplied under categories a and b, which are used to withstand liquid pressure, must also undergo hydrostatic testing.
3. Seamless tubes for specialized useBoiler Seamless TubeA variety of seamless steel tubes, including those for power use, geological purposes, and oil applications.
Seamless steel tubes feature hollow cross-sections and are extensively used as pipelines for conveying fluids, such as oil, gas, water, and certain solid materials. Compared to solid steel materials like round bars, they are lighter in weight while maintaining the same bending and torsional strength, making them an economical section steel.
Broadly used in the manufacturing of structural components and mechanical parts, such as oil drilling rods,Automotive Drive ShaftCircular components made from steel pipes, such as bicycle frames and steel scaffolding for construction, can enhance material utilization, simplify manufacturing processes, save materials and processing time, and are widely used in pipe manufacturing.
