ERW273 welded pipe mill
Production Description
The forming fundamental of ERW tube mill
The forming fundamental of tube mill: the slit strip is formed into approximate round steel tube without welding by the forming mill,and then the tube’s edge is melted and welded by the HF induction welder and the welded seam is squeezed Immediately after welding at welding section of tube mill .At this stage, the steel pipe welding is completed, the welded tube through cooling and sizing mill and straightening stand, the final precision steel round or square&rectangular tube is done
The description of ERW273 welded tube mill
1)ERW273welded tube mill is one model of ERW tube mills .The ERW273 welded tube mill utilizes HF induction welding to manufactureØ114mm---Ø273mm steel tube and 70X70mm---200x200mm square tube and 60X80mm-150X250mm rectangular tube with the thickness 4.0--10.0mm .
2)ERW273 welded tube mill has conventional forming technology, it is ideal for round tube , square&rectangular tube.best control on the tube dimension tolerance and length accuracy.
3)ERW273welded tube mill is a tailored-made steel tube production line . We are able to design and manufacture the tube mill as per customer’s requirement ,Such as ,the steel tube diameter and thickness , raw material type and raw material yield strength ,specification of tube mill and your floor space dimension,power supply condition .
Before making quotation ,we will send the customer a request form to customer’s specific requirement. So that we make quotation that completely meet customer’s demand.
4)We are not only a provider of tube mill, but also a provider of solution for the problem that arise in the course of Pre-sales, in sales, and after-sales
