Spiral pipe, also known as spiral steel pipe or spiral welded pipe, is made by rolling low carbon structural steel or low alloy structural steel strip into a pipe blank at a certain spiral angle (called forming angle), and then welding the pipe seams made. This manufacturing method allows the production of larger diameter steel pipes using narrower strips of steel
It is suitable for seamless steel pipes for high temperature resistance, low temperature resistance and corrosion resistance in petroleum, chemical industry, electric power and boiler industries
