Seamless steel pipes are made by piercing a solid round steel billet, which results in pipes without any visible welds on the surface. Depending on the production method, seamless steel pipes 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 their cross-sectional shape. Non-round tubes come in various complex shapes such as square, elliptical, triangular, hexagonal, pumpkin-shaped, star-shaped, and winged tubes. Diameters range up to 900mm and down to 4mm. Depending on their applications, they haveThick-walled Seamless Steel PipeAnd薄壁 Seamless Steel PipeSeamless steel pipes are primarily used for oil...Geological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, as well as high-precision structural steel pipes for automobiles, tractors.
Seamless steel pipes with no seams along the periphery of their cross-section. They are divided into different types based on their production methods.Hot-rolled pipeCold Rolled TubeCold Drawn TubeExtruded Tube,Jacking 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-resistant, etc.) categories, divided by application.
1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolling, high yield, mainly used for pipes or structural parts conveying fluids.
2. Offered in three categories based on different applications:
Supply based on chemical composition and mechanical properties.
b. Supply based on mechanical properties
c、As perWater Pressure TestSupply. Steel pipes supplied under categories a and b, if used to withstand liquid pressure, must also undergo hydrostatic testing.
3. Seamless tubes for specialized useBoiler Seamless PipeA wide range of seamless steel tubes, including power, geological, and oilfield applications.
Seamless steel tubes feature a hollow cross-section and are extensively used as pipelines for conveying fluids, such as oil, gas, water, and certain solid materials. Compared to solid steel products like round bars, they are lighter in weight while maintaining the same bending and torsional strength, making them an economical section steel.
Widely used in the manufacturing of structural and mechanical components, such as oil drilling rods,Automotive Propeller ShaftSteel pipe is widely used to manufacture circular components for bicycle frames, steel scaffolding for construction, and other applications, which can enhance material utilization, simplify manufacturing processes, save materials and labor hours.
