20# Seamless Steel Tube, OD 114*14, Thin-Walled Seamless Tube

Seamless steel pipes are pipes made by piercing a solid round steel billet, which have no seams on the surface and are referred to as seamless steel pipes. According to the production method, seamless steel pipes can be divided 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 circular and non-circular shapes based on their cross-sectional shapes. Non-circular tubes come in various complex forms, including 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 vary.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, as well as high-precision structural steel pipes for automobiles, tractors.

Seamless steel pipes without joints along their cross-sectional circumference. They are categorized according to different production methods.Hot-rolled pipeCold Rolled PipeCold 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 pipes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolling, high output, mainly used for pipeline or structural parts for conveying fluids.

2. Offered in three categories based on different applications:

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

Seamless steel pipes feature hollow 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.

Widely used in the manufacturing of structural and mechanical components, such as oil drilling rods.Automotive drive shaftCircular components made from steel pipes, such as bicycle frames and steel scaffolding for construction, enhance material efficiency, simplify manufacturing processes, save materials and labor, and are widely used in pipe manufacturing.
