Flanges & Forgings

We are specialist in forged flanges, rings, discs and special forgings.

Our Flanges have various dimension standards such as ANSI B 16.5, B 16.1, B 16.47 Series 'A' and 'B', MSS SP-44, 10K, 16K, EN/DIN, JISSK and BS 4504 and can also be designed as per the specifications of our clients. These feature varied pressure rating that ranges from 150 to 2500 lbs. We manufacture flanges in compliance with the international norms and standards in various grades.      


Flanges, rings, discs and special forgings:
- dimensions from 1/2'' till 120''
- dimensions from DN15 till DN3000
- pressure from 150 lbs, 300 lbs, 600 lbs, 900 lbs, 1500 lbs till 2500 lbs
- pressure from PN2,5, PN6, PN10, PN16, PN25, PN40, PN63 (PN64), PN100, PN160, PN250, PN320 till PN400
