Q355B Seamless Steel Pipe 133*10 Seamless Steel Pipe Alloy Seamless Pipe

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 tubes、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 shapes. Non-round tubes come in various complex shapes, including square, elliptical, triangular, hexagonal, pumpkin-shaped, star-shaped, and winged tubes. Diameters range from 900mm to as small as 4mm. Depending on their applications, they differ.Thick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel tubes are mainly 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.

Seamless steel tubes with no joints along their cross-sectional perimeter. Divided into different types based on production methods.Hot-rolled tubeCold rolled tubeCold Drawn TubeExtruded Tube,Jacking PipeEach has its own process specifications.

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 steelRolling, high yield, mainly used for pipe or structural parts conveying fluids.

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

Available by chemical composition and mechanical properties.

b. Supply based on 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 pipes for specialized useBoiler Seamless PipeElectricity, geological, and oil seamless steel pipes, and various types.

Seamless steel tubes 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 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 drilling rods.Automotive Drive ShaftCircular components made from steel pipes, such as bicycle frames and steel scaffolding for construction, can enhance material utilization, streamline manufacturing processes, save materials and labor hours, and are widely used in pipe manufacturing.
