Seamless steel pipes are pipes made by piercing a solid round steel billet, featuring no welds on the surface and are referred to as seamless steel pipes. According to the production method, seamless steel pipes can be categorized into...Hot-rolled Seamless Steel Pipe、Cold-rolled Seamless Steel Pipe、Cold Drawn Seamless Steel PipeExtruded seamless steel pipes, jacking pipes, etc. Seamless steel pipes are categorized into circular and non-circular shapes, with non-circular pipes available in various complex forms such as square, elliptical, triangular, hexagonal, pumpkin-shaped, star-shaped, and winged pipes. Diameters range from 900mm to 4mm. Depending on their application, they vary.Thick-walled Seamless Steel PipeAndThin-walled Seamless Steel PipeSeamless steel tubes are primarily used in the oil industry.Geological Drilling PipeCracking pipes for oil, boiler pipes, bearing pipes, as well as high-precision structural steel pipes for automobiles, tractors.
Seamless steel tubes with no seams along their cross-sectional periphery. They are categorized based on different production methods.Hot Rolled PipeCold Rolled PipeCold Drawn TubeExtruded tubesDirect pipe jackingAll have their respective 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 resistance, etc.) are divided into two categories according to their applications.
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 components for fluid conveyance.
2. Offer three types of supplies based on different applications:
a. Supplied 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 special purposesBoiler Seamless PipeElectricity and geological use seamless steel pipes, as well as oilfield seamless pipes and more.
Seamless steel tubes 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 cross-section steel.
Broadly used in the manufacturing of structural components and mechanical parts, such as oil drill pipes.Automotive Propeller ShaftSteel pipe components for bicycle frames and steel scaffolding used in construction are manufactured using钢管, which enhances material utilization, simplifies production processes, and saves on materials and processing time.钢管 is widely used for such manufacturing.
