Industrial Flanges Manufacturer

What Is a Flange?
A flange is a mechanical component used to connect pipes, valves, pumps and other equipment in pipeline systems. Two flanges are bolted together with a gasket in between to create a secure and leak-proof connection.
flanges are widely used in oil & gas, petrochemical, power generation, water treatment and pipeline construction projects. They allow convenient installation, inspection and maintenance of piping systems.

Types of Flanges We Supply
We provide a complete range of industrial flanges for high-pressure and low-temperature applications:

Weld Neck Flange (WN) – Suitable for high-pressure and high-temperature pipelines

Blind Flange (BL) – Used to close the end of a pipeline system

Slip-On Flange (SO) – Easy installation for medium and low-pressure systems

Socket Weld Flange (SW) – Ideal for small diameter high-pressure pipelines

Threaded Flange (TH) – Applied where welding is not permitted

Lap Joint Flange (LJ) – Designed for systems requiring frequent dismantling
