Large Diameter Seamless Steel Pipe | Hot Rolled & Hot Expanded Carbon Steel Tube
Large diameter seamless steel pipe is solid‑billet manufactured pipe without welding seam. Available in hot‑rolled and hot‑expanded processes for carbon steel, alloy & stainless steel. Widely used for fluid transportation, petrochemical, power and structural engineering. MTC / MTR certification provided upon request. Custom sizes, end finishing and anti‑corrosion treatment are available.
Thin‑Wall Seamless Steel Tube
Thin‑wall seamless steel tube is manufactured from solid steel billet via piercing, hot rolling, cold‑drawing or cold‑rolling processes. Featuring light self‑weight, good yield strength and tensile strength, uniform wall thickness. Cold‑finished tubes deliver tight dimensional tolerance and smooth surface finish.
We supply carbon steel, alloy steel and stainless‑steel thin‑wall seamless tubes complying with ASTM, EN, DIN international standards.
Alloy Seamless Steel Tube
Supply alloy seamless steel tube in 16Mn,40Cr,15CrMo,12Cr1MoV,42CrMo grades. Hot‑rolled & cold‑drawn options. Approximate international equivalent grades, custom sizes and MTR test report available for boiler, petro‑chemical & machinery use.
Fluid‑service seamless steel tubes
Fluid‑service seamless steel tubes are pressure‑bearing seamless steel tubes designed for conveying media such as water, oil, gas and steam. Primarily applied for pressure piping, these tubes are subject to mandatory hydrostatic testing on every single piece per GB/T8163‑2018 to prevent pressure‑induced pipeline leakage.
