What is a Stainless Steel 304H pipe, and what makes it different from other stainless steel pipes?
Stainless Steel 304H pipe is a variant of the popular grade 304 stainless steel. It is designed to offer enhanced high-temperature strength and improved creep resistance compared to standard 304 stainless steel pipes. The "H" in 304H denotes its higher carbon content, which provides increased tensile strength and high-temperature capabilities. This higher carbon content also enables the formation of more carbides, enhancing the pipe's resistance to sensitization during welding or exposure to high temperatures.

Stainless Steel 304H 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.
