Precision seamless steel tube
Positioning: Mechanical structural application
Application: Machining, hydraulic cylinder, automotive components
Core Selling Points: Tight dimensional tolerances, bright surface free of scale, high surface finish
Tolerance: ±0.05 mm; higher precision available upon contract customization
Surface: Bright & scale‑free, Ra0.8 μm
Size Range: OD 4mm‑400mm; notable advantage in thin‑wall tubes
Hydraulic Cylinder Barrel Blank Seamless Steel Tube, Pre‑Honing Tube
Hydraulic cylinder barrel blank seamless steel tube is raw material for manufacturing hydraulic and pneumatic cylinder barrels. It is NOT finished honed cylinder tube. Machining allowance is reserved for inner bore, further boring and honing processes are required to get final cylinder barrel.
Small Diameter Seamless Steel Pipe, Hot Rolled & Cold Drawn Steel Tube
Small diameter seamless steel pipe is produced by hot‑rolled or cold‑drawn process without welding seam. Cold‑drawn version features high dimensional accuracy and smooth surface. Carbon steel, alloy steel and stainless steel available. MTR / MTC certificate provided. Custom sizes, end finishing and export packing are offered.
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.
