ERW32 Tube Mill

The forming fundamental of ERW tube mill

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 afterwelding 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

The description

✦ERW32 welded tube mill is one model of ERW tube mills .The ERW32 welded tube mill utilizes HF induction welding to manufacture Ø10mm---Ø32mm steel tube and 10X10mm---25x25mm square tube 10X20---20X30mm rectangular tube with the thickness 0.4--2.0mm .

✦ERW32 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

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.

✦ERW32 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

Our advantage

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 application of tube and hollow profile

The ERW tubes and profiles produced by the pipe mill can be utilized in the industry below:
✦Metal Furniture: Frames and support structures for chairs, tables, bed frames, sofas, coat racks, and bookshelves.
✦Outdoor Furniture: Armrests and brackets for park benches and beach chairs.
✦Fitness Equipment: Frames for home or light commercial fitness equipment, such as treadmills, elliptical trainers, exercise bikes, and parallel bars.
✦Medical Equipment: Brackets and handles for wheelchairs, hospital beds, IV poles, and carts.
✦Mechanical Equipment: Frames, ventilation ducts, and protective covers for various light mechanical equipment.
✦Decoration and Art:Indoor and Outdoor Decoration: Decorative guardrails, screens, partitions, display racks, and supermarket shelves.
✦Bicycles and Motorcycles: Components such as handlebars, subframes, and luggage racks.
✦Automobiles: Interior support, ventilation ducts, and wiring harness protection.
✦Display and Storage Equipment:display racks: Merchandise display racks and booth frames in shopping malls and showrooms.
✦Shelves: Lightweight storage racks, bookshelves, shoe racks, etc.

The benefit

HIGH ACCURACY

The components of forming and sizing machine has high accuracy ,this results in the accuracy of forming and sizing are assured . therefore, the accuracy of steel pipe are assured.

HIGH INTERCHANGEABILITY

Each component has interchangeability,which require less spare parts as standby.

Easy maintenance

He forming and sizing with seldom failure and easy maintenance,which ensure the maximum up-time with smooth and trouble-free production,this result in enhanced productivity.

THE TUBE SHAPE

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.
