114*6 20# Seamless Steel Pipe, Thin-Walled Seamless Pipe

Seamless steel tubes are manufactured by piercing a solid round steel billet, resulting in pipes without any 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 round and shaped types based on cross-sectional shape. The shaped tubes come in various complex shapes, including square, elliptical, triangular, hexagonal, pumpkin-shaped, star-shaped, and winged tubes. Diameters range up to 900mm and down to 4mm. Depending on their application, they areThick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel pipes are mainly used in the oil industry.Geological Drilling PipeCracking pipes for oil, boiler tubes, bearing tubes, as well as high-precision structural steel tubes for automobiles, tractors.

General-purpose (used for water, gas pipelines and structural components, mechanical parts) and specialized (used for boilers, geological exploration, bearings, acid-resistant, 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 pipelines or structural parts for conveying fluids.

2. Offered in three categories based on different applications:

Available by 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 specialized useBoiler Seamless PipeA variety of seamless steel tubes for electrical and geological use, as well as for oil applications.

Seamless steel tubes feature a hollow cross-section 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 are lighter in weight with the same bending and torsional strength, making them an economical cross-section steel.

Widely used in the manufacture of structural and mechanical components, such as oil drill pipes,Automotive drive shaftSteel pipe is widely used to manufacture circular components for bicycle frames and steel scaffolding for construction, which can enhance material utilization, simplify manufacturing processes, and save on materials and processing time.
