PRODUCT INQUIRY

Seamless steel tube, as the name suggests, is a pipe without seam or weld-joint. Seamless steel tube is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.
