About Dipti Metal Industries

Founded in 2009 by Mr. Kumpsingh Rajput, Dipti Metal Industries is a trusted DIN 2655 manufacturer, DIN 2655 exporter, DIN 2655 supplier, and stockist of DIN 2655 loose flanges with plain collars (PN 25). Under our registered brand “Dipti,” we supply premium flanges to clients in over 40 countries across Europe, North America, Asia, the Middle East, and Africa, supporting industries like oil & gas, waterworks, energy, and chemical processing.


What Are DIN 2655 Loose Flanges?

The DIN 2655 standard specifies loose (lap joint) flanges with plain collars designed for PN 25 (25 bar) pressure rating. These flanges are manufactured so the flange ring can rotate freely around the welded collar, simplifying alignment and assembly during installation.

Multilingual Terminology:

  • English: Loose flange and ring for welding – Rated pressure 25

  • Español: Brida loca y anillo de soldar – Presión nominal 25

  • Deutsch: Lose Flansche Glatte Bunde – Nenndruck 25

This design is especially suited for piping systems that require frequent dismantling, inspection, or maintenance.
