DIN EN / DIN Flanges

We at rff grew on handling in flanges. We have earned a name as a competent partner in this field over the years as reflected in the depth and breadth of our stock and delivery programme.

We are experts in flanges that we supply in any shape and design to any standard. Even so, our focus extends beyond flanges according to DIN EN 1092-1 to flanges according to common DIN standards as are still used in container and equipment construction as well as in shipbuilding. 

We also supply weld neck flanges for mechanical welding according to DIN 21057-6 as mainly used in the chemical industry. We have them in stock, by the way. 

Designs and standards

Standardised DIN and EN flanges are extremely diverse. We would therefore recommend that you enquire about the dimensions and pressure ratings available in our supply range. We supply all common flanges and pressure ratings according to DIN or DIN EN 1092-1.
