Manufacturing Process for Stainless Steel Pipe and Tube

Tube mill Process description of stainless steel pipe and tube:

Rolling and welding

Firstly, the stainless steel strips are made to go through various quality checks and are trimmed at edges. 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 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 there after use.

Advantages of Carbon Steel Pipe Fittings

When purchasing steel pipe fittings, it’s important to take into consideration certain factors, most importantly size and shape, to ensure that it is a perfect match for your specific purpose. However, another important aspect to consider is the material used in the making of the pipe fitters. Certain elements added to the steel, such as carbon and chrome, can dramatically affect its strength and appearance. Here are a few great reasons to invest in carbon steel pipe fittings as well as chrome plating.

Durability

Steel is one of the most popular types of pipe fittings and has been used for construction of pipes and pipe fittings for years because of its durability and strength. However, carbon steel, or plain-carbon steel, has the ability become much   stronger through heat treatment.  The more carbon added to the steel, the stronger it can become, which is why it is considered one of the strongest types of steel. Another way to increase the durability is to create a harder surface by adding a layer of chromium. Chrome plated pipe fittings are not only durable, but prevent corrosion and may also make the cleaning process much easier.

Multi-purpose

Carbon steel pipe fittings are typically used for industrial purposes such as commercial construction, electric-power, petroleum refinement and the building of ships, but are also often seen in the household.  They are used for fire sprinkler systems and pipes carrying water, types of flammable gasses, oil or steam. Because of the addition of carbon to the steel, carbon steel pipes and pipe fittings are also much more resistant to rust.  Again, chrome plated pipe fittings will also help to prevent rust and will keep steel looking newly polished. Because chrome plating has a naturally bright appearance, it is utilized more in the automobile industry.

Variety

Because steel has the ability to undergo heat treatment, it’s easy to find carbon steel pipe fittings with just the right amount of carbon for any purpose. Mild carbon steel is typically used when a project calls for a large amount of steel because of its lower price and standard usage. Medium carbon steel is mostly utilized in the automotive industry due to its erosion resistance. Due to its strength, high carbon steel is used in the making of wires and springs. However, once the carbon content reaches 1.0%, it is only used for specific, non-industrial purposes.
