108*12 20# Seamless Steel Pipe Thin-Wall 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 Pipe、Cold Drawn Seamless Steel PipeExtruded seamless steel tubes, jacking pipes, etc. Seamless steel tubes are divided into circular and non-circular shapes based on cross-sectional shape. Non-circular 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 down to 4mm. Depending on their applications, they differ...Thick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel tubes are mainly used for oil...Geological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors.

General-purpose (used for water, gas pipelines and structural components, mechanical parts) and specialized (used for boilers, geological exploration, bearings, acid resistance, etc.) categories, divided by application.

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 parts for conveying fluids.

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

Supply based on chemical composition and mechanical properties.

b. Supply based on 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 special applicationsBoiler Seamless PipeA variety of seamless steel tubes for power and geological use, as well as oil seamless pipes.

Seamless steel tubes feature hollow cross-sections and are extensively used as piping for conveying fluids, such as oil, gas, water, and certain solid materials. Compared to solid steel materials like round bars, they have the same bending and torsional strength but are lighter in weight, making them an economical section steel.

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