Sprinkler pipe is usually produced through Electric resistance welding process which is forming a seam by electric-resistance welding, wherein the edges to be welded are mechanically pressed together and the heat for welding is generated by the resistance to flow of electric current applied by induction or conduction. The general application is fire protection.
