Mild Steel Flange Manufacturers in Indore| Kolkata Pipe Fittings

Kolkata Pipe Fittings, is a former mild steel flanges manufacturers, suppliers, dealers, stockists and traders in Indore. We are providing the strong quality of MS flanges that are usually used to securely connecting pipes, valves, pumps and other types of piping systems.

These are made from strong quality of mild steel and other types of raw materials and applied in different types of industrial sectors such as oil and gas, water treatment, chemical processing and construction industries also. These flanges create a strong, leak proof seal when bolted together.

Types of Our Mild Steel Flanges

Being the best mild steel flanges manufacturers and suppliers in Indore, we are providing the top quality of MS flanges which are highly used as per requirement from multiple types of industrial sectors:

Slip-On Flange (SO Flange): These are more easy for installation process and slip on flange is specially designed to fit over the outside of the pipe and once it is aligned, these can be welded from both inside and outside to ensure a secure connection. These flanges are highly used in low to medium pressure systems.
Weld Neck Flange (WN Flange): This flange has a long and tapered type of neck and it is welded to the pipe. This can provides a smooth transition in between the pipe and flanges. For using these flanges in high pressure applications, these are built with better stress distribution. Our weld neck flanges are made with advanced types of steel alloys and advanced metallurgy manufacturing process.
Blind Flange: In these blind flanges, the seal is connected to the end process of the pipeline and isolate sections of piping systems. These are no other types of openings in these blind flanges and most useful for creating a temporary seal or for maintenance purpose. For using in extreme temperature and chemicals, we have used different types of composite materials in these blind flanges such as fiberglass reinforced polymers.
Socket Weld Flange (SW Flange): In these socket weld flanges, the pipe is inserted into the flange socket and the connection is made by welding around the perimeter of the pipe and typically used for small diameter purpose and handling higher pressure ratings. Our SW flanges are majorly applied in the precision machining industrial sectors due to design and working mechanism structure. These flanges are basically gives tight tolerances and better fittings of pipes.
