Manufacturing Process Of Duplex S32205 Pipes

Rolling and Welding

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 TIG welding process.

Length Cutting

Rolled pipes and tubes thus manufactured are cut to the required lengths depending upon the industrial demand. We use a variety of methods—sawing, lathe cutting, rotary cutting, supported shear cutting, dual-blade shear cutting, and laser cutting.

Cleaning and Heating Phase

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.

Cold Drawing Process

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 tube or pipe is drawn over the bench using Die plugs.

Finishing Process

Pipe and tubes are then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine then mark the finished pipes or tubes. Then they marked with grade of material, size, heat number.
