Thick-walled Seamless Steel Pipe 114*16, Seamless Steel Pipe Q355B

Seamless steel tubes are pipes made by piercing a solid round steel billet, featuring no weld seams on the surface and are referred to as seamless steel tubes. Depending on the production method, seamless steel tubes can be categorized into...Hot-rolled Seamless Steel Pipe、Cold-rolled seamless steel tubes、Cold Drawn Seamless Steel PipeExtruded Seamless Steel Tubes, Jacking Pipes, etc. Seamless steel tubes are divided into circular and irregular shapes based on cross-sectional shape. Irregular 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. Depending on their applications, they areThick-walled Seamless Steel PipeAnd薄壁 Seamless Steel PipeSeamless steel tubes are primarily used for oil applications.Geological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, as well as 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 categorized by their applications.

1. General-purpose seamless steel tubes 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. Offered in three categories based on different applications:

Available by chemical composition and mechanical properties.

b. Supplied according to mechanical properties;

c. As perHydrostatic TestSupply. Steel pipes supplied under categories a and b, used to withstand liquid pressure, must also undergo hydrostatic testing.

3. Seamless tubes for specific applicationsBoiler Seamless PipeA variety of seamless steel tubes for electrical and geological use, as well as for oil applications.

Seamless steel pipes feature 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 like round bars, they are lighter in weight while maintaining the same bending and torsional strength, making them an economical section steel.

Broadly used in the manufacture of structural and mechanical components, such as oil drill pipes.Automotive Drive ShaftCircular components made from steel pipes, such as bicycle frames and steel scaffolding for construction, can enhance material utilization, simplify manufacturing processes, save materials and labor hours, and are widely used in pipe manufacturing.
