Product Details

spiral ductwork Spiral pipe edge milling machine is used to improve the edge condition of welded pipe forming plate, so that the welded steel strip can get good edge condition and surface roughness before entering the forming and welding process, which has an important influence on the forming and welding quality of welded pipe.Spiral steel pipe edge milling machine can meet the welding quality requirements of different steel pipe wall thickness and process I, Y and X groove.Spiral steel pipe edge milling machine milling groove shape is accurate and consistent, conducive to forming and welding, is the ideal groove for welding, especially thick plate can milling X groove, avoid the phenomenon of not welding penetration, and can effectively reduce the height of the weld seam to get the ideal weld shape, and is conducive to the corrosion of steel pipe internal and external surface operations
