Seamless steel tubes are made by piercing a solid round steel billet and have no weld seams on the surface, hence the name "seamless steel tube." According to the production method, seamless steel tubes 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 round and non-round shapes based on their cross-sectional shapes. Non-round tubes come in various complex shapes such as square, elliptical, triangular, hexagonal, pumpkin-shaped, star-shaped, and winged tubes. Diameters range up to 900mm and down to 4mm. Depending on their applications, they vary.Thick-walled Seamless Steel PipeAndSlim-walled Seamless Steel PipeSeamless steel tubes are mainly used for oilGeological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors.
Seamless steel pipes with no joints along the circumference of their cross-section. They are categorized based on different production methods.Hot-rolled pipeCold-rolled tubesCold drawn tubeCompression TubeJacking PipeEach has its own process specifications.
Material options include standard andCarbon structural steel(Q215-A to Q275-A and 10 to)50# steelLow-alloy steel (09MnV, 16Mn, etc.), alloy steelStainless acid-resistant steelPlease wait.
General-purpose items (used for water, gas pipelines and structural components, mechanical parts) and specialized items (used for boilers, geological exploration, bearings, acid-resistant, etc.) are categorized by their applications.
1. General-purpose seamless steel tubes are made from ordinaryCarbon structural steel、Low-alloy structural steelOrAlloy structural steelRolled, high yield, mainly used as piping or structural components for 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 TestSupplies. Steel pipes supplied under categories a and b, if used to withstand liquid pressure, must undergo hydrostatic testing.
3. Seamless tubes for special applicationsBoiler Seamless PipeElectricity, geological, and oil seamless steel pipes, and various types.
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 products 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, such as bicycle frames and steel scaffolding for construction, can enhance material utilization, streamline manufacturing processes, and save on materials and processing time, and are widely used in pipe manufacturing.
