Cold-expansion process has been developed for ensuring dimensional precision of inside geometry on the end portions of line pipe. For expanding the inside diameter of line pipe, a plug insertion method by cold press in the axial direction from the end side was finally adopted. Sturdy, Stainless cold expanded steel line pipe for Stainless and galvanized cold expanded steel line pipe for industrial and commercial purposes at . These hot-dipped cold expanded steel line pipe are ideal for seamless construction uses.
Cold-expanded longitudinal seam submerged-arc welded (SAW) pipe fabricated using the UOE process (U forming, O Forming, Expanded fabricated from plate). Cold expansion is conducted to achieve satisfactory roundness and reduce residual stress. Non-cold-expanded longitudinal SAW pipe is fabricated using pyramid rolling and contains high
