Welded pipe making machine is the main equipment for the welded tube production line with roller forming principle, feed the steel strip , with roller function, tube billets are formed, then the tube edge will be heated to welding temperature due to the high frequency equipment. After finishing the process of cooling, sizing, straightening, the tube will be made. The mill is composed of uncoiler, leveling machine, butt welder, loop, straightening machine, high frequency equipment,etc.
High frequency welded pipe making machine is the main equipment for the welded steel tube production line with decoiler, strip feeding, roller forming and sizing, high frequency solid welding, cutting and stock.
ERW273 high frequency longitudinal welded pipe production line / pipe making machine / tube mill is designed to produce welded pipes of 114mm-273mm in OD and 3.0mm-10.0mm in wall thickness, as well as corresponding square and rectangular pipe.
