Manufacturing Process of Stainless Steel Pipes and Tubes – Step-by-Guide

The only method available in the nineteenth century for producing stainless tubes and pipes for industrial use was rolling mill technology. Long procedures were required for this rolling technique. With the aid of funnel rolls, the sheet metal strips that had been rolled were cut into a circular cross-section. The forge welding procedure was then used to perform the lap welding on these rolled strips.

Thankfully, with the advancement of development and technology, various processes for the manufacture of stainless steel tubes and pipes in India have emerged. Nowadays, stainless steel pipes and tubes are manufactured using a continuous tube mill and multi-torch tungsten inert gas. This technique does not employ the use of filler metal or the forge welding process.

Stainless Steel Pipes and Tubes Manufacturing – Step-by-Step Guide

Rolling and welding.

First, various quality checks are made, and then the edges of the stainless steel strips are trimmed. Stainless steel pipe manufacturers in India then feed them into the tube mill. The strips are routed through the required number of rollers. The strip is gradually transformed into a tubular shape in the tube mill. The fitted welding machine is then used to TIG weld the strip’s trim edges. The Tibo machine removes scraps and welds beads in an instant. Rolled pipes and tubes are created in this manner.

Heating and Cleaning

Depending on the industrial demand, the rolled stainless steel pipes are cut to the required lengths. The stainless steel pipes and tubes are then cleaned to remove the dirt. Furthermore, these rolled pipes and tubes are heat treated to remove stresses caused by welding and formation processes. The continuously rolling hearth furnace is used for heat treatment. Temperature recorders and controllers are installed in the furnace. Following the heat treatment process, the SS tubes and pipes are straightened and pickled to remove surface scales.

Cold-drawing Procedure

In some cases, the required size may not be available directly from the mill. The cold operation process can then be used to achieve the desired size. The tubes or pipes are coated with oxalic acid and soap solution during the cold drawing process. This solution acts as a lubricant, reducing friction during the cold drawing process. The tube or pipe is drawn over the bench using die plugs during the cold drawing process.

Process of Completion

The drawn-out tube or SS pipe is then cleaned, heat treated, pickled, and straightened. The finished pipes or tubes are marked using a computerized ink jet marking machine. Before being passed on to stainless steel pipe exporters, the pipe or tube is marked with the grade of material, size, heat number, and the stamp of third party inspection. The resulting stainless steel tubes or pipes will be subjected to rigorous testing and quality control. This is followed by proper packing and shipping. There are numerous stainless steel pipe applications for which these pipes and tubes are used.
