ERW165 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 ERW165 welded tube mill
1)ERW165 welded tube mill is one model of ERW tube mills .The ERW165 welded tube mill utilizes HF induction welding to manufacture Ø76mm---Ø165mm steel tube and 60X60mm---130x130mm square tube and 40X80mm-100X600mm rectangular tube with the thickness 2.0--6.0mm .
2)ERW165 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)For the square and rectangular tube production . We can provide 2 forming processes as option .
Option1: the steel strip is shaped into round tube by forming machine .after HF welding , the round tube is shaped into square or rectangular tube by sizing machine ,and then the square or rectangular tube is straightened by 2 -Turkey head .
Option2:The steel strip is shaped into round tube by forming machine .after HF welding , the round tube is shaped into square or rectangular tube by 4-Turkey head ,and then the square or rectangular tube is straightened by the 5th -Turkey head One of the forming processes can be determined as per the quantity of square&rectangular and round tube .so that the roller investment can be saved maximum.
4)ERW165welded 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.
5)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
