Hot-Rolled Seamless Pipe: Outer diameter typically greater than 32mm with wall thickness ranging from 2.5-75mm. Suitable for general steel pipe, low/medium pressure boiler applications, high pressure boiler requirements, alloy steel applications, stainless steel needs, oil cracking operations, geological exploration, and specialized steel pipe applications.
Cold-Rolled (Drawn) Seamless Pipe: Offers superior dimensional accuracy with diameters as small as 6mm and wall thickness down to 0.25mm. Thin-walled variants available with outer diameters from 5mm and wall thickness below 0.25mm.
