(1)ERW89 welded tube mill is one model of ERW tube mills .The ERW89 welded tube mill utilizes HF induction welding to manufacture Ø38mm---Ø89mm steel tube and 35X35mm---70x70mm square tube and 30X40---50X100mm rectangular tube with the thickness 0.8--4.0mm .
(2)ERW89 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 3-Turkey head ,and then the square or rectangular tube is straightened by the 4th -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)ERW89 welded 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

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.Heavy Industrial Structures and Machinery (Core Applications)
✦Large Industrial Equipment Frames: The main frames and bases of medium-sized CNC machining centers, laser cutting machines, press brakes, injection molding machines, hydraulic presses, and other machinery.
✦Heavy-Duty Conveying and Automation Systems: The frames and guide rails of heavy-duty conveyors in automotive production lines, warehouse logistics sorting lines, and large assembly lines.
✦Workstation Equipment and Fixtures: Large welding positioners, mold supports, and the body structures of heavy-duty material handling vehicles.
✦Warehousing Systems: The columns and beams of heavy-duty and ultra-heavy-duty racks, used to store palletized goods, can bear loads of several tons or more.
2. Buildings and Infrastructure
✦Steel Structures: Main beams, secondary beams, and inter-column supports for medium-sized factories, warehouses, stadiums, and supermarkets. Compared to smaller sizes, pipes of this size can withstand larger spans and loads.
✦Large Public Facilities: Support structures for bus shelters, train station canopies, and stadium stand roofs.
✦Bridges and Passageways: Large equipment maintenance passages within factories and main beams for small pedestrian overpasses.
✦Large Safety Protection: Heavy-duty guardrails for machinery and equipment, high-strength fencing around factory perimeters, and central isolation piers on highways.
3. Fluid and Gas Transportation (Main Applications for Round Pipes)
✦Industrial Main Pipelines: Main compressed air pipelines, cooling water circulation pipelines, and hydraulic system pipelines within factories.
✦Oil, Gas, and Chemical Industries: Low-pressure oil and gas transportation, chemical media transportation (material selection and anti-corrosion treatment must be tailored to the media).
✦Municipal Applications: Main pipelines for residential heating and water supply networks.
4. Transportation and Vehicle Manufacturing
✦Commercial Vehicles and Special Purpose Vehicles: Truck chassis subframes, bus and long-distance coach body frames (square tube truss structures), sanitation truck body structures, and concrete mixer truck tank supports.
✦Cranes and Construction Machinery: Internal support structures for telescopic booms of mobile cranes and booms of aerial work platforms.
✦Agricultural Machinery: Frames and protective structures for large tractors and harvesters.
✦Rail Transit: Subway and train carriage underframe auxiliary structures, seat frames.
5. Other Applications
✦Light Poles and Flagpoles: Streetlight poles (internal structures or small poles) on urban roads, large flagpoles in squares and businesses.
✦Large Sports Equipment: The entire support frame of basketball hoops, soccer goals, and the main frame of large fitness equipment.
✦Offshore Platforms and Vessels: Partition frames within ship cabins, handrails and guardrails on platforms.
Additional to the round tube,square&rectangular tube and octagonal tube , Welded tube mill also manufacture the special welded tube and profile as per customer’s drawing,Such as L/T /Z shape tube and ROPS and FOPS tube which can meet the need of various industry.
