108*20 20# Seamless Steel Pipe, Thick-Walled Seamless Pipe

Seamless steel tubes are made by piercing a solid round steel billet and do not have any welds on the surface, hence the name "seamless steel tube." According to 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 round and shaped types according to their cross-sectional shape. The shaped tubes come in various complex shapes, including square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and winged tubes. Diameters range up to 900mm and down to 4mm. Depending on their application, they areThick-walled Seamless Steel PipeAndSlim-walled Seamless Steel PipeSeamless steel tubes are primarily used for oilGeological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, as well as high-precision structural steel pipes for automobiles, tractors.

Material options include standard andCarbon structural steel(Q215-A to Q275-A and 10 to)50# steelLow-alloy steel (09MnV, 16Mn, etc.), alloy steel,Stainless acid-resistant steelPlease wait.

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

1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolling, high yield, mainly used for pipeline or structural components conveying fluids.

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

a. Supplied by chemical composition and mechanical properties;

b. Supplied by mechanical properties

c、As requestedWater 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 specific applicationsBoiler Seamless PipeElectricity and geological use seamless steel tubes, as well as oilfield seamless pipes and more.

Seamless steel tubes feature hollow 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, seamless steel tubes are lighter in weight while maintaining the same bending and torsional strength, making them an economical cross-sectional steel.

Broadly used in the manufacturing of structural components and mechanical parts, such as oil drill pipes.Automotive Propeller ShaftCircular components made from steel pipes, such as bicycle frames and steel scaffolding used in construction, can enhance material utilization, simplify manufacturing processes, save materials and processing time, and have been widely used in pipe manufacturing.
