The forming would be carried out progressively and gradually formed into an open-seam pipe. The SAW welding process would be used and the pipe would be transported through an exact guidance in order to prevent edge offset and creates a uniform welding line. The outside weld is applied through to the inside weld in such a way that the material fuses and combines with the outside weld material to form a homogeneous structure for the best quality. Pipe end Facing and chamfering ensure satisfactory welding together of the pipes and exactly plane – parallel pipe ends for an accurate and clean match.
