Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng electromechanical equipment spiral welded pipe for you to resolve common defects in how to detect when two spiral welded pipe equipment aside less resection margin, since testing equipment layout reason pipe equipment, spiral pipe two heads are sometimes not useful detection, and the tip is most capable of cracks or other disadvantages of the site. If the spiral welded pipe ends there a potential tendency to crack pipe equipment, welding heat affected device when there are potentially able to expand the crack. Thus pipe equipment manufacturers, but also should pay attention to post-test must be welded spiral welded area, to discover expanding spiral welded ends shortcomings. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. is a high-tech enterprise specialized in the design, development and manufacture of welded pipe equipment, spiral welded pipe equipment, cold-formed steel equipment, sheet and pipe finishing equipment and high-precision slitting line equipment. Taiyuan Huaxin Cheng Electrical Equipment Co., Ltd. of Longitudinal Longitudinal unit after the unit is a certain width slitting steel through uncoiling, leveling into the machine, use the roll into a round steel tube bending , re-use of the high-frequency current skin effect and proximity effect in a very short time to melt the edge of the strip, extruded by the squeeze rollers so that the surface of the oxide layer and the impurity is extruded blend substrate, thereby forming tube. Longitudinal molding unit is divided into: FF forming, roll forming row, FFX molding. Our products specifications: φ34 ~ φ610mm, wall thickness: 0.8 ~ 16mm all Longitudinal unit.
