Stainless Steel Seamless Pipe Manufacturer in India

Stainless steel seamless pipes are typically used in chemical industries, in food processing and in pharmaceuticals. There are hundreds of stainless steelseamless pipe manufacturers in India, some operating on a large scale while many are small to medium sized units. Stainless steel seamless pipes are manufactured in a variety of ways.

One method is to use stainless steel rod as base and then pierce a hole into it after which it is rolled and heated to ensure a perfect profile. Another method is to use an extrusion mill. Stainless Steel bars are used as feedstock. They are fed through a tube into a die of appropriate dimensions to give seamless pipes of the desired wall thickness and diameters. Another process is gun drilling. Here the feedstock is a pretreated round stainless steel bar. It is drilled using a flute drill to give SS pipes of precise diameters and wall thicknesses. The tubes can go through a further process of heating, annealing and hardening for use as pressure pipes. Cold forming is a specialized process in which the SS tube is cold drawn through a die. This yields SS pipes for specialist applications. Of all these processes extrusions is the cheapest and gives maximum production.

Though there are hundreds of stainless steel seamless pipe manufacturers in India, you do not know about the quality of the SS pipe and whether it will suit your specific application. Some may not anneal the feedstock tube in an annealing furnace, for example. Only a few SS pipe manufacturers can give you seamless SS pipes of the type and quality so it is best to inquire into details to know you are getting true value for money.
