Forged Flanges

Flanges are designed to join pipes, pumps, valves, and other units in a piping system. Additionally, it facilitates access for inspection, cleaning, and modification. There are different standards of flanges in the market. Yet, we manufacture flanges according to your specific regulations.

Spacers

Spacers are the safety devices used during maintenance tasks to isolate the line section to replace or inspect. Unlike valves, these spectacle blinds serve as a permanent blocking device. The spacers are designed under industry standards and customer specifications.

Custom-designed flanges

We design and develop special forged flanges for the most complex engineering projects. We develop these products in compliance with the highest international standards.
