Menu Stainless steel flanges POSTED ON 24 JUNE 2020BY SERGIO BISCACCIANTI The flange is a mechanical element intended for a non-permanent coupling of other pieces by means of screws or bolts. Pipe flanges are used for the non-permanent joining of two pipe sections. The set of a pipe delimited by the flanges (including them) is called "spool". The European standard relating to flanges for pipes is EN1092-1 and establishes the requirements for steel flanges, classifying them on the basis of nominal pressure (PN), Nominal Size (DN), Type (TYPE) and finally a letter relating to the surface of flange seal. The most common types of flanges available from stock at S.Inox are the following: FLANGE FLANGE TO WELD (EN 1092-1 TYPE 01-A) It is the most common type of welding flange, it is identified as TYPE01 and the letter A indicates a flat sealing surface. They are overlapped and the coupling is ensured by bolts. FLAT FLANGE TO BE WELDED WITH STEP (EN 1092-1 TYPE 01-B) It differs from the previous one only for the sealing surface. In this type of flanges there is in fact a collar in low relief around the central hole used for the insertion of a gasket generally in Silicone, Teflon or EPDM. Also in this case the flanges are overlapped and coupled by bolts. FLAT SLIDING FLANGE or FREE FLANGE (EN 1092-1 TYPE 02A) Si tratta di flange libere da montare in accoppiamento a cartelle a saldare. Il collegamento è effettuato mediante bulloni. Per questa tipologia di flange sono anche diffuse le alternative: EN AB 47000 – in alluminio verniciato; DIN 2642 – flange stampate. FLANGE CIECHE (EN 1092-1 TYPE 05A) Queste flange vengono utilizzate come terminale di chiusura delle tubazioni. Possono essere accoppiate indifferentemente con qualsiasi tipologia di flangia piana a saldare. FLANGE A COLLARINO (EN 1092-1 TYPE 11B) In questa tipologia di flange la saldatura è realizzata “di testa” e la superficie di tenuta è a gradino. CARTELLE (EN 1092-1 TYPE 33) Le cartelle da utilizzare in accoppiamento alle flange libere (EN 1092-1 TYPE 02A) o alle flange stampate (DIN264) vengono identificate dalla norma UNI come TYPE 33.
