(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

1.We have gradually abandoned the idea of designing only two-dimensional drawings. We now design not only two-dimensional drawings but also 3D drawings.
With advanced 3D modeling and drafting software, allows us to analyze functionality of each part and make any improvements as needed.We can promptly detect design errors
2.31 sets of CNC vertical machining center and 6 sets of CNC horizontal machining center,3 sets CNC boring machine , 2 set of heavy duty CNC gantry milling machine have been in use. This lead to tight accuracy and high productivity, In this way, errors caused by match machining can be avoided, Meanwhile, the delivery time can be ensured.
3.With the advanced COPPRA software , Out engineer not only calculate the roller weight but also design roller at high efficiency.
The ERW tubes and profiles produced by the pipe mill can be utilized in the industry below:
1.Building Structures: Factory trusses, stadiums, exhibition centers, main structures of high-rise buildings, and construction supports (scaffolding).
2. Bridges and Infrastructure: Bridge guardrails, auxiliary pier structures, docks, and road guardrails.
3. Machinery and Equipment Manufacturing: Agricultural machinery (such as harvester frames), conveyor rollers, and injection molding machine frames.
4. Fluid Transportation: Water supply and drainage networks, process piping within petroleum and petrochemical plants, and heating systems.
5. Low-Pressure Fluid Transportation: Low-Pressure Gas, Steam, and LPG Transportation.
6. Power and Communications: Electrical Wire Conduits and Transmission Towers.
