Hastelloy Seamless Pipe

Hastelloy Seamless Pipe Manufacturer, Supplier in India

Hastelloy Seamless Pipe is a type of pipe made from the corrosion-resistant alloy known as Hastelloy. This alloy is composed of various metals, including nickel, chromium, molybdenum, and tungsten, which give it exceptional resistance to a wide range of corrosive environments. The key features of Hastelloy Seamless Pipe lie in its remarkable corrosion resistance, high strength, and excellent thermal stability. These pipes can withstand extreme temperatures, making them suitable for high-pressure and high-temperature applications.

Additionally, Hastelloy Seamless Pipe exhibits excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, making it a preferred choice in chemical processing, petrochemical, oil and gas, pharmaceuticals, and power generation industries. With its superior performance and reliability, Hastelloy Seamless Pipe is crucial in ensuring the integrity and longevity of critical systems and infrastructure in demanding environments.

What industries typically use Hastelloy Seamless Pipe and why?

Hastelloy Seamless Pipe finds widespread use in various industries due to its exceptional corrosion resistance and high-performance characteristics. Industries such as chemical processing, petrochemical, oil and gas, pharmaceuticals, and power generation extensively utilize Hastelloy Seamless Pipe. In chemical processing and petrochemical industries, where exposure to highly corrosive chemicals is common, Hastelloy Seamless Pipe's resistance to corrosion and pitting makes it an ideal choice for transporting and containing corrosive fluids. Similarly, in the oil and gas sector, these pipes are used for offshore and onshore applications, where they provide reliable performance in harsh environments, including exposure to corrosive fluids, high pressures, and extreme temperatures.

In the pharmaceutical industry, where precision and purity are crucial, Hastelloy Seamless Pipe ensures the integrity of the manufacturing processes by preventing contamination and maintaining product quality. Lastly, in power generation applications, including nuclear and coal-fired power plants, Hastelloy Seamless Pipe is employed for its ability to withstand corrosive gases, high temperatures, and demanding conditions within the power generation systems.

Rolling and welding

Firstly, the hastelloy strips are made to gone through various quality checks and are trimmed at edges. They are then fed to the tubes mill by hastelloy 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 hastelloy 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 alloy 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 hastelloy 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 hastelloy pipe applications, these pipes and tubes are used thereafter for.
