DIN 2673 Loose Flanges (PN 10) — Manufacturer, Exporter & Supplier in India

About Dipti Metal Industries

Founded in 2009 by Mr. Kumpsingh Rajput, Dipti Metal Industries is a leading DIN 2673 manufacturer, DIN 2673 exporter, DIN 2673 supplier, DIN 2673 dealer, and stockist of DIN 2673 loose flanges with welding-neck collars (PN 10). We export under the “Dipti” brand to 40+ countries across North America, Europe, the Middle East, Africa, and Asia with full documentation and global standards compliance.

What Is DIN 2673?

DIN 2673 defines a two-piece, lap-joint style assembly: a welding neck collar butt-welded to the pipe and a loose ring flange that rotates freely for quick bolt-hole alignment. This construction is ideal for low-pressure systems (PN 10) that require frequent assembly, inspection, or replacement.

Multilingual terminology for buyers:

• English: Loose flange and ring with neck for welding — Rated pressure 10

• Español: Brida loca y anillo con cuello para soldar — Presión nominal 10

• Deutsch: Lose Flansche mit Vorschweißbund — Nenndruck 10
