Le présent document spécifie les exigences applicables à la conception, aux matériaux et aux dimensions des raccords à bague vissée pour flexibles en caoutchouc et en thermoplastique destinés à être utilisés avec des liquides et des gaz inflammables et ininflammables, comme par exemple les flexibles de distribution de carburant, les flexibles pour gaz naturel liquéfié (GPL), les flexibles de camions citernes et flexibles pour produits chimiques liquides et gazeux. Il couvre les diamètres nominaux DN 13 à DN 40.
Jusqu’au DN 25, la pression maximale de service est de 25 bar, pour les DN 32 et DN 40 la pression maximale de service est de 16 bar.
La plage de températures de service est de -20 °C à +65 °C, pour utilisations GPL elle est de -30 °C à +70 °C jusqu’au DN 25 et pour utilisations à basse température de -50 °C à +70 °C.
Cevni fitingi z vijačnimi pušami
Ta evropski standard določa načrtovanje, materiale in dimenzije cevnih fitingov z vijačnimi pušami za gumene in plastomerne cevi za uporabo z vnetljivimi ali nevnetljivimi plini, npr. za cevi za točenje goriva, cevi za tekoči zemeljski plin (LPG), cevi za TW cisterne in cevi za tekoče in plinaste kemikalije. Obravnavane nominalne velikosti so od DN 13 do DN 40. Do DN 25 je največji delovni tlak 25 barov1), za DN 32 in DN 40 pa je največji delovni tlak 16 barov. Razpon delovne temperature je od -20 °C do +65 °C, za uporabo za LPG do DN 25 od -30 °C do +70 °C in za uporabo pri nizki temperaturi od -50 °C do +70 °C.
