Seamless steel tubes are made by piercing a solid round steel billet, resulting in pipes without any 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 tube、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, melon-shaped, star-shaped, and winged tubes. Diameters range up to 900mm and as small as 4mm. They vary in use.Thick-walled Seamless Steel PipeAnd薄壁 Seamless Steel PipeSeamless steel pipes are primarily used for oilGeological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, as well as high-precision structural steel pipes for automobiles, tractors.
Seamless steel pipes without seams along their cross-section. They are divided into different types based on the production method.Hot-rolled tubeCold Rolled PipeCold Drawn TubeExtruded tubesJacking PipeAll have their respective process specifications.
Material options include standard andCarbon structural steel(Q215-A to Q275-A and 10 to)50# steelLow-alloy steel (09MnV, 16Mn, etc.), alloy steel,Stainless acid-resistant steelPlease wait.
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 categorized by their application.
1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolling, high yield, primarily used for piping or structural components to convey fluids.
2. Offered in three categories based on different applications:
Available by chemical composition and mechanical properties.
b. Supplied according to mechanical properties
c. As perWater Pressure 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 purposesBoiler Seamless PipeVarious types, including seamless steel tubes for power and geological use, as well as seamless pipes for oil 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 equivalent bending and torsional strength, making them an economical section steel.
Broadly used in the manufacturing of structural components and mechanical parts, such as oil drill pipes.Automotive Propeller ShaftSteel pipe is widely used to manufacture circular components for bicycle frames, steel scaffolding for construction, and other applications, which enhances material efficiency, simplifies manufacturing processes, and saves materials and processing time.
