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.
1)ERW426welded tube mill is one model of ERW tube mills .The ERW426 welded tube mill utilizes HF induction welding to manufactureØ219mm---Ø426mm steel tube and 150X150mm---350x350mm square tube and 100X200mm-300X400mm rectangular tube with the thickness 4.0--10.0mm .
2)ERW426 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)ERW426welded 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. Large Buildings and Structures: Stadiums (main trusses, roof trusses), airport terminals, large convention and exhibition centers, columns and main beams of high-rise and super-high-rise buildings, and giant trusses of industrial plants.
2. Critical Infrastructure: Major components of bridges (such as arch ribs and piers), support piles at ports and docks, wind turbine tower segments (often used in small and medium-sized wind turbines or internal tower structures), and the main materials of high-voltage transmission towers.
3. Oil, Gas, and Chemical Transportation: Oil and natural gas gathering and transportation pipelines, urban gas trunk networks, process pipelines in chemical parks, and heat source trunk lines for heating companies.
4. Heavy Equipment Manufacturing: Construction machinery (excavators, crane booms and crawler frames), shipbuilding (interior structures and piping), mining machinery (hydraulic supports, conveyor structures), and rollers and frames for large material handling systems.
5. Support and Piping Systems: Coal mine support columns, large hydraulic equipment (such as cylinder casings), and load-bearing columns for industrial platforms.
