Seamless steel tubes are made by piercing a solid round steel billet, resulting in tubes 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 round and irregular shapes based on their cross-sectional shape. Irregular tubes come in various complex shapes, including square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and winged tubes. Diameters range up to 900mm and as small as 4mm. Depending on their application, they are available in different types.Thick-walled Seamless Steel PipeAnd薄壁 Seamless Steel PipeSeamless steel tubes are primarily used for oilGeological Drilling PipeCracking pipes for oil, boiler tubes, bearing tubes, as well as steel tubes for automotive, tractor, and high-precision structural applications.

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 output, mainly used for piping or structural components to convey fluids.
2. Offer three categories of supply based on different applications:
a. Supplied 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 special applicationsBoiler Seamless PipeVarious types, including seamless steel tubes for power and geological use, as well as seamless pipes for oil applications.
Seamless steel pipes 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, seamless steel pipes are lighter in weight while offering 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 drill pipes.Automotive Propeller ShaftSteel pipe components, such as bicycle frames and steel scaffolding for construction, are manufactured using steel pipes, which enhance material efficiency, simplify production processes, save materials, and labor hours, and are widely used in steel pipe manufacturing.
