89mm x 10mm OD 20# Seamless Steel Pipe

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 tubeExtruded seamless steel tubes, jacking pipes, etc. Seamless steel tubes are divided into round and non-round shapes according to their 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 from 900mm to 4mm. Depending on their applications, they areThick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel tubes are mainly used for oil applications.Geological Drilling PipeCracking pipes for oil use, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors.

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 based on their applications.

1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolled, high yield, primarily used for piping or structural components to convey 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 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 PipeElectricity, geological, and oil seamless steel pipes, among others.

Seamless steel pipes have 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 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 components and mechanical parts, such as oil drill pipes.Automotive Propeller ShaftCircular parts made from steel pipes for bicycle frames and steel scaffolding used in construction are widely used to enhance material utilization, simplify manufacturing processes, and save materials and processing time.
