Rolling Mill Machine

▷ Tube Mill Machine | Rolling mill machine | LOTOS 2021 ◁ is a new welding technology, which coats thin stainless steel on the surface of carbon steel pipe with high strength, the product has the features of both artistic appearance, therefore, corrosion resistance of stainless steel and high strength of carbon steel. It is the best substitute for stainless steel pipe as its lower price compared with that of welded steel pipe.

Pipe Production Line

The tube mill is widely used in household commodities, shoe racks, public facilities, and guardrails such as all kinds of clothes racks, retractable poles, article racks, all-purpose combination racks, tables, and chair legs, indoor handrails, ship and bus racks, and outdoor guardrails.

steel tubing  is an automation system to produce pipes, square tubes, shaped tubes

Tube Mill  or Pipe Production Line Process :

Firstly, the stainless steel strips are made to go through various quality checks and are trimmed at the edges. The strips pass through the number of rollers as per the required size. In the tube mill, the strip is gradually converted into a tubular shape. The fitted welding machine is then used to weld trim edges of the strip welding process. In this way, rolled pipes and tubes are formed.

The cleaning and heating phase Welded Tube Mill Line

The rolled stainless steel pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless pipes and tubes are then subjected to cleaning to remove the dirt. Further, a heat treatment is given to these rolled pipes and tubes to remove the stresses that may occur due to welding and formation processes. Heat treatment is given on the continuously rolling hearth furnace. The furnace is fitted with temperature recorders and controllers. After the heat treatment process, the stainless steel tubes and pipes are straightened and subjected to pickling for removing scales from the surface.

Cold- drawing process roll forming mill

In some cases, the required size may not be obtained from the mill directly. Then, the cold operation process can be used to obtain the desired size. In the cold drawing process, the tubes or pipes are coated with oxalic and soap solution. This solution acts as a lubricant to reduce friction while cold drawing operation.

Finishing process Square Pipe Mill Steel Tube Manufacturing Machine

The drawn-out tube or stainless steel pipe is then subjected to cleaning, heat treatment, pickling, and straightening. The computerized inkjet marking machine is used to do the marking on the finished pipes or tubes.

Working Flow Welding Pipe Mill Machine

Raw material (steel coil) → uncoiling → shearing and butt-welding → material accumulating → non-power leveling →mill-forming → high-frequency welding → removing burrs outside of weld seam → Zinc spraying → cooling → sizing → roughly straightening → fixed-length cutting → run-out table
