✦ERW50 welded tube mill is one model of ERW tube mills .The ERW50 welded tube mill utilizes HF induction welding to manufacture Ø20mm---Ø50mm steel tube and 15X15mm---40x40mm square tube and 10X20---50X30mm rectangular tube with the thickness 0.4--2.0mm .
✦ERW50 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.
✦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.
✦ERW50 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.
✦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.Structural Frames and Supports (This is the primary use)
✦Machinery Casings and Frames: Automation equipment, machine tool protective covers, conveyor line supports, workbenches, equipment bases, etc.
✦Warehouse Racking and Material Shelving: Beams and columns for light- and medium-duty racking.
✦Display Racks and Supermarket Shelves: Display racks and showcase frames in shopping malls and showrooms.
✦Furniture Manufacturing: Steel-wood tables and chairs, bed frames, filing cabinets, storage racks, etc.
✦Architectural Decoration and Partitioning: Examples include stair railings, guardrails, interior partition ribs, and sunroom frames.
2. Fluid Transport
✦Circular pipes are primarily used to transport low-pressure fluids and are common pipes for media such as water, gas, air, and oil.
✦Water and Gas Transport: Low-pressure water and gas pipes within buildings (must comply with relevant safety standards).
✦Compressed Air Piping: Air supply lines for pneumatic tools in factory workshops.
✦Hydraulic and Lubrication Systems: Some low-pressure hydraulic systems and lubrication lines for mechanical equipment.
✦Agricultural irrigation: Sprinkler and drip irrigation system pipes in greenhouses.
3. Automobile, motorcycle, and bicycle manufacturing
✦Automotive parts: Exhaust system tailpipes, undercarriage components, seat rails, etc.
✦Motorcycles and electric bikes: Frames, rear forks, bumpers, etc.
✦Bicycles: Bicycle frames (mostly made of higher-strength chromium-molybdenum steel, but ordinary carbon steel can also be used for lower-end models).
4. Other industrial and everyday applications
✦Flagpoles and light poles: Smaller diameters can be used as flagpoles or garden light poles in residential areas and schools.
✦Sports equipment: Frames for soccer goals, basketball hoops, and fitness equipment.
✦Greenhouses: Serving as arch poles and longitudinal tie rods for greenhouses.
✦Distribution boxes/cabinets: Serving as the internal support structure of the enclosure.
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.
