In the nineteenth century, rolling mill technology was the only technology used to manufacture stainless steel tubes and pipes for industrial use. This rolling technique involves a very long procedure. With the help of funnel rolls, the rolled strip is shaped into a circular cross-section. Lap welding is then performed on these rolled strips by a forging welding process.
Thankfully, with the advent of development and technology, the production process of various stainless steel pipes and pipes in India began to emerge. Now, stainless steel pipes and tubes are manufactured using multi-tungsten tungsten inert gas continuous tube mills. No filler metal or forge welding processes are used in this technique.
1. Stainless steel tube and tube manufacturing process
Tube mill process description: rolling and welding
First, the stainless steel band passes various quality checks and is trimmed at the edges. It is then fed into a tube mill by a stainless steel tube manufacturer in India. Depending on the required size, the steel strip is passed through a number of rollers. In a tube mill, the steel strip gradually becomes tubular. The trimmed edge of the strip is then welded using a TIG welding process using an assembled welding machine. Scrap and internal welds are instantly removed by the Tibo machine. In this way rolled tubes and tubes are formed.
2. Cleaning and heating stage
The rolled stainless steel tubes thus produced are cut to the required lengths according to industrial requirements. These stainless steel pipes and tubes are then cleaned to remove contamination. In addition, these rolled tubes and tubes are heat treated to relieve stress that may occur due to the welding and forming process. The heat treatment is carried out on a continuous rolling hearth furnace. The furnace is equipped with a temperature recorder and controller. After the heat treatment process, the SS pipes and tubes are straightened and pickled to remove scales on the surface.
3. Cold drawing process
In some cases, the required dimensions may not be available directly from the mill. Then, a cold working process can be used to obtain the desired dimensions. During cold drawing, the pipe or pipe is coated with a solution of oxalic acid and soap. This solution acts as a friction-reducing lubricant during cold drawing operations. During cold drawing, a die plug is used to pull the tube or tube through the table.
Fourth, the finishing process
The drawn tube or stainless steel tube is then cleaned, heat treated, pickled and straightened. Computer inkjet marking machines are used to mark finished tubes or tubes. The pipe or tube is marked with material grade, size, number of heats and third party inspection marks before delivery to stainless steel pipe exporters. The stainless steel pipes or pipes produced in this way will undergo certain testing and quality checks. This process is followed by proper packaging and shipping. There are countless applications for stainless steel pipes and these are used after this.
