The heat resistance of Stainless Steel 321 / 321H pipes makes them highly sought after in the aerospace industry, particularly for exhaust systems and jet engine components. These pipes also find utility in power generation plants, where they are utilized in boiler systems and heat exchangers. Their exceptional weldability and formability make them suitable for fabrication in various industries such as food processing, pharmaceuticals, pulp and paper, where hygiene, durability, and reliability are crucial.

What are the key properties and characteristics of Stainless Steel 321 / 321H pipe? Stainless Steel 321 pipe possesses several key properties and characteristics, making it a highly desirable material for various applications. It exhibits excellent corrosion resistance, particularly against intergranular corrosion and oxidation, even in high-temperature environments. This corrosion resistance is due to the addition of titanium, which stabilizes the material against sensitization during welding or prolonged exposure to elevated temperatures. Stainless Steel 321 pipe offers good mechanical properties, including high tensile strength and good toughness, enabling it to withstand high-pressure and high-stress conditions.

Stainless Steel 321H pipe shares many of the key properties and characteristics of its counterpart, Stainless Steel 321. However, it possesses an additional attribute that sets it apart. The "H" in Stainless Steel 321H denotes its higher carbon content, which provides enhanced creep resistance and improved high-temperature strength. That makes Stainless Steel 321H pipe particularly suitable for applications where prolonged exposure to elevated temperatures is expected.

Stainless Steel 321 Pipe Manufacturing Process

Rolling and welding

Firstly, the stainless steel strips are made to gone 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 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.

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 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.

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 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.

Finishing process

The drawn-out tube or ss pipe is then subjected to cleaning, heat treatment, pickling and straightening. The computerized ink jet marking machine is used to do the marking on the finished pipes or tubes. The pipe or tube is marked with 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.
