Tube and Pipe Mills - Coil End Joiners Increase Productivity
With the introduction of coiled steel approximately 100 years ago, welded tube and pipe mills became popular. A tube mill begins with an uncoiler, straightener, and shear end welder at the entry of the line. The "forming" part of the mill is made of a breakdown section and forming section that takes 3 to 6 passes. Each pass is made up of a lower and upper arbor containing roller die tooling which gradually forms the steel into a tube shape. Several more passes are made to get the new tube ready to weld. The seam on the tube is welded by a solid state welder or high frequency welder. Sometimes the inner and outer bead are removed before the sizing section. There, the tube is made to conform to the desired dimensions. Finally the new pipe is cut to length. Titanium Tube Like it does with other metal forming lines, a coil end joiner shears ends of strips, butts them, and then makes a smooth weld so that the joined coil can proceed through the metal forming line.
