Stainless Steel 316 Square Pipe

Stainless Steel 316 Square Pipe Manufacturer, Supplier in India

316 / 316L Square Pipes find a wide range of applications across various industries due to their excellent properties and versatility. These pipes are highly sought after in chemical processing, oil and gas, pharmaceuticals, food and beverage, marine, and architectural applications.

In chemical processing plants, 316/316L square pipes are commonly used for transporting corrosive chemicals and fluids due to their exceptional corrosion resistance. They can withstand exposure to various aggressive media, including acids, alkalis, and chlorides.

In the oil and gas industry, these square pipes are utilized for offshore drilling, subsea pipelines, and refineries, where they exhibit excellent resistance to chloride-induced stress corrosion cracking and pitting. The high strength and durability of 316/316L stainless steel make them suitable for harsh environments and extreme temperatures.

What are the key properties and characteristics of 316/316L square pipes?

316 Square Pipes possess several key properties and characteristics that make them highly desirable in various industries. They exhibit excellent corrosion resistance, particularly against corrosive chemicals, acids, and chlorides, making them suitable for applications in chemical processing and marine environments. 316 square pipes demonstrate high strength and durability, enabling them to withstand harsh conditions and extreme temperatures, making them ideal for oil and gas applications. They offer good weldability and formability, allowing for easy fabrication and installation. 316 square pipes have hygienic properties, making them suitable for use in pharmaceutical and food processing industries where cleanliness and prevention of contamination are crucial.

316L Square Pipes share many key properties and characteristics with their 316 counterparts while offering additional advantages. One notable feature of 316L square pipes is their enhanced corrosion resistance, especially in environments exposed to chlorides and other corrosive substances. This property makes them highly suitable for industrial applications such as chemical processing, marine and coastal areas. Furthermore, 316L square pipes exhibit excellent weldability and formability, allowing easy fabrication and installation. They also possess good strength and durability, making them capable of withstanding demanding conditions and temperature variations.

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 seamless 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.
