Seamless steel tubes are formed by piercing a solid round steel billet, which results in a tube without any visible welds on its 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 round and non-round shapes based on cross-sectional shape. Non-round tubes come in various complex shapes such as square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and winged pipes. Diameters range up to 900mm and down to 4mm. Depending on their application, they vary.Thick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel tubes are mainly used for oil applications.Geological Drilling PipeCracking pipes for oil, boiler tubes, bearing tubes, as well as steel tubes for automobiles, tractors, and high-precision structural applications.
Seamless steel pipes without joints around their cross-sectional perimeter. They are classified into different types based on the production methods.Hot-rolled pipeCold Rolled PipeCold Drawn TubeExtruded tubesJacking PipeEach has its own process specifications.

General-purpose (used for water, gas pipelines and structural components, mechanical parts) and specialized (used for boilers, geological exploration, bearings, acid resistance, etc.) categories, divided by application.
1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolled, high output, mainly used as pipes or structural components for conveying fluids.
2. Offer three categories of supply based on different applications:
a. Supplied by chemical composition and mechanical properties
b. Supply based on 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 special applicationsBoiler Seamless TubeVarious types, including seamless steel tubes for electric use, geological use, and oil use.
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 have the same bending and torsional strength but are lighter in weight, making them an economical section steel.
Widely used in the manufacturing of structural components and mechanical parts, such as oil drill pipes.Automotive Propeller ShaftSteel pipe is used to manufacture circular components for bicycle frames and steel scaffolding for construction purposes, which improves material utilization, simplifies manufacturing processes, saves materials and processing time, and has been widely used for such purposes.
