(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 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）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

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.
1.Structural Support and Construction (Core Applications)
✦Industrial Building Main Structures: Used in main load-bearing columns and long-span truss beams in buildings such as large industrial plants, warehouses, hangars, stadiums, and commercial centers. These structures require sufficient strength and stability from steel pipes, which LSAW pipes fully meet.
✦Tower Structures: Used in communication towers, power towers, the internal structure of wind turbine towers, and high-mast lighting poles. Hot-dip galvanizing is typically required for corrosion resistance.
✦Bridge Components: Used in pier supports, guardrails, and auxiliary support structures under bridge decks for pedestrian and highway bridges.
✦Port and Offshore Engineering: Used in the booms and support structures of port cranes, dock bollard supports, and walkways and auxiliary platform supports on offshore platforms (requiring heavy-duty anti-corrosion treatment).
2. Fluid Transportation (Medium and Low Pressure)
✦Straight seam welded pipe is a cost-effective option for transporting fluids such as water, gas, and oil, and is particularly suitable for large-diameter pipes.
✦Municipal Water Supply Network: Used as main or branch pipelines to transport tap water.
✦Industrial Piping Systems: Used in factory circulating water systems, fire sprinkler systems, compressed air pipelines, low-pressure steam pipelines, etc.
✦Oil and Gas Transportation: Used in gathering and transportation pipelines within oil and gas fields to transport crude oil and natural gas (typically requiring strict weld quality and inspection requirements).
✦Agricultural Irrigation: Used as main irrigation pipes for large farmlands.
3. Machinery Manufacturing and Vehicles
✦Heavy Machinery Frames: Used as frames and support components for large mining machinery, construction machinery (such as non-core pressure-bearing supports), conveying equipment, and large packaging machinery.
✦Vehicle Manufacturing: Used in chassis frames (longitudinal and transverse beams, often made of rectangular tubes), body frames, and exhaust systems (after-processor housings) for trucks, buses, and trailers.
✦Warehousing and Logistics: Columns and beams used in heavy-duty racking and automated storage/recycling systems (AS/RS), with load-bearing capacities exceeding several tons.
4. Pillars and Foundation Engineering
✦Large Equipment Foundation Pillars: These include the supporting legs of large hydraulic presses, ship gantry cranes, and stage lighting rigs.
✦Pile Foundation Pipes: In certain foundation projects, these can serve as micropiles or support piles, particularly in larger diameter sizes.
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.
