SPIRAL PIPE PRODUCTION FAULT CORRECTION

An error occurred within the allowable range, the production of any article can not guarantee any of a good quality product, as long as the production of spiral pipe when the error rate can be reduced to a minimum. Pipe production process to correct errors, improve production quality, has become the manufacturer must be controlled.
In the spiral shape, the strip camber angle will constantly change shape, leading to changes in the weld gap, resulting in open seam, wrong side or even take sides. Seriously affecting the quality of the steel, so the observation strip coil-camber situations after, by controlling the vertical rolls so that the disc can be cut and removal of part of camber angle forming the continuous control and corrective camber of the strip is the reduction in the production process effective way of generating the wrong side. Because of the poor do not trimming the strip head and tail shape and size precision, easy to cause docking strip hard bend caused by the wrong side. Strip head and tail docking high over larger weld seam when molding over if not handled properly, likely to cause greater wrong side. Poor strip edge condition is another important reason for the wrong side. Identify the problems in the correct lot easier.
