SSAW pipe mill machine is used for spiral welded pipe production, different diameters pipes can be made with the same steel strip and same diameter be made of different widths. The forming unit is the key equipment of the production line. Spiral welded steel pipe is widely applied to various fluid conveying such as petroleum natural gas and water as well as construction structural pipes and piling pipes etc.The production mode of spiral line include front swing type and back swing type. the front swing type is the conventional spiral line, intermittent production with less cost, small floor space. The back swing type is continuous spiral line with features of higher cost, large floor space.
GEIT GROUP offers spiral pipe welding machine which produce spiral pipes from suze Φ219-Φ3220mm, thickness 5-25.4mm.
