Carbon Seamless Steel Pipe 

Seamless steel pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless steel pipe 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.

Hot Rolling Seamless Steel Line Pipe Manufacturing / Production processes

Rolled Round Billets – Examination – Cut Off – Heating – Piercing – Elongation – Slight Tension Reducing – Straightening – Corp End Cutting Off – Visual Inspection – NDT – Hydrostatic Test – Ends Procession – Product Inspection – Painting and Marking – Packing – Warehousing

Cold Drawn (Rolled) seamless steel pipe manufacturing process

Mother pipe (Normally for hot rolled pipe) – Inspection – Annealing – Ends Treatment (Hitting and Drilling hole) – Pickling – Grinding – Phosphorization (Annoit) – Cold Drawn (Rolled) – Degreasing and Cleaning – Heat treatment (Solution treatment) – Straightening – Hydrostatic test – Painting and Marking – Warehousing
