FLANGES
ABOUT OUR FLANGES
What Are Industrial Pipe Flanges?
Flanges are mechanical components used to connect pipes, valves, pumps, pressure vessels, and other equipment in a piping system. They create secure and leak-proof joints while allowing easy access for inspection, maintenance, cleaning, and future modifications.
Industrial flanges are joined using bolts and gaskets and are available in multiple designs, materials, pressure ratings, and international standards to suit various operating conditions.
At Manibhadra Metals, we supply high-quality industrial flanges manufactured to meet international specifications for demanding industrial applications.
