Seamless Steel Pipe/Tube: Seamless steel pipe is a type of steel pipe made of a single piece of metal with no joints on the surface. The production methods include hot rolling, cold rolling, cold drawing, extrusion, and pipe jacking. Available in circular and irregular shapes including square, elliptical, triangular, hexagonal, etc.
The diameter varies from 650 millimeters to several millimeters, with wall thicknesses ranging from thick-walled to thin-walled. Widely used for conveying fluids, structural components, boilers, chemicals, electricity, petroleum, and automotive manufacturing.
