Steel Pipe: Stainless Steel Pipe and Tube Manufacturing Process

Steel Pipe: Stainless Steel Pipe and Tube Manufacturing Process
Issue Time:2019-08-08
#1 Rolling and welding
Firstly, the stainless steel strips are made to go through various quality checks and are trimmed at edges. They are then fed to the tubes mill by stainless steel pipe manufacturers in India. The strips pass through the number of rollers as per the required size. In the tubes-mill, the strip is gradually converted into the tubular shape. The fitted welding machine is then used to weld trim edges of the strip using the TIG welding process. The scraps and inside weld bead are removed instantaneously by the Tibo machine. In this way, rolled pipes and tubes are formed.

#2 The cleaning and heating phase
The rolled stainless steel pipes thus manufactured are cut to the required lengths depending upon the industrial demand. These stainless steel 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 SS tubes and pipes are straightened and subjected to pickling for removing scales from the surface.

#3 Cold- drawing process
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. In the cold drawing process, the tube or pipe is drawn over the bench using Die plugs.

#4 Finishing process
The drawn-out tube or ss 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. The pipe or tube is marked with a grade of material, size, heat number and the stamp of third party inspection before passing on to stainless steel pipe exporters. The stainless tubes or pipes thus produced will undergo certain testing and quality checks. This process is followed by proper packing and dispatch. There are numerous numbers of stainless steel pipe applications, these pipes and tubes are used thereafter for.
