Flanges, fittings & connection
Flanges, pipe fittings, gaskets and connecting elements – to DIN EN and ASME/ASTM, matched to each other. Everything for the tight, standard-compliant connection.
Flanges – types and pressure ratings
Flanges in all standardised types and pressure ratings. The availability of individual dimensions and pressure ratings is limited and should be enquired in advance. In principle we supply all common flanges to EN 1092-1, DIN and ASME.
| Standard | Types | Range |
|---|---|---|
| EN 1092-1 / DIN 2627–2638 | Weld-neck, flat, loose, blind, threaded | PN 6 to PN 400 |
| ASME B16.5 | WN, SO, BL, TH, LJ, SW | Class 150 to 2500 (½"–24") |
| ASME B16.47 A / B | Large flanges | Class 75 to 900 (26"–60") |
Pipe fittings, gaskets & connection
Fittings matched to the pipe as well as the complete connecting material – to DIN EN and ASME.
