Straight seam welded steel pipe production mode with continuous and discontinuous type two kinds, the main difference is that the former has stored in the unit strip loop device, to ensure the continuity of the unit production;While the latter by not storing strip loop device, when the head and tail docking two coil, production units to broadly in weld discontinuities in the back of the process to use manual repair welding.Straight seam welded pipe units are mostly of modern new continuous.
Straight seam welded pipe production process include: billet welding preparation, forming, pressure test and finish machining process.Different sets of the above process part of the content is not the same.(1) tube billet preparation including strip uncoiling, leveling, shearing and butt welding, etc.
(2) forming welding including forming, welding, weld cleaning.Check, cooling and sizing and cutting head, tail and cutting length.
(3) the finishing processing including straightening, examination, flat head, the water pressure test, repair welding, finished product inspection, car wire processing and printing packaging, etc.
