20# Seamless Steel Tube, 89*6

Seamless steel tubes are formed 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 categorized into circular and non-circular shapes based on their cross-sectional form. Non-circular 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 areThick-walled Seamless Steel PipeAnd薄壁 Seamless Steel PipeSeamless steel tubes are primarily used in the oil industry.Geological Drilling PipeCracking pipes for oil, boiler tubes, bearing tubes, as well as steel tubes for automotive, tractor, and high-precision structural applications.

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 according to their applications.

1. General-purpose seamless steel pipes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolling, high yield, mainly used for piping or structural components for conveying fluids.

2. Offer three categories of supply based on different applications:

Available by chemical composition and mechanical properties.

b. Supplied by 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 specialized useBoiler Seamless TubeA variety of seamless steel tubes for power, geological use, and oil applications, among others.

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 with the same bending and torsional strength, making them an economical section steel.

Widely used in the manufacturing of structural components and mechanical parts, such as oil drill pipes.Automotive Propeller ShaftCircular components made from steel pipes for bicycle frames and steel scaffolding used in construction are widely used as they enhance material efficiency, simplify manufacturing processes, and save on materials and processing time.
