Flange steam couplings EN14423/ DIN2826

 

Steam couplings complying with EN 14423/ DIN 2826 are available in female and male threaded screw couplings and in flange couplings. The screw couplings are available in galvanized steel, stainless steel or brass. The flanged couplings are available in galvanized steel or stainless steel.

Steam couplings complying with EN 14423 / DIN 2826 are used to assemble steem hoses complying with EN ISO 6134. The serrated hose shank with collar is designed to be assembled with RKS steam clamps complying with EN 14423 / DIN 2826. Under no circumstances RK safety clamps complying with EN 14420-3/ DIN 2817 shall be used. Compared with EN 14420-2 / DIN 2817-compliant smooth hose shanks, steam hose shanks complying with EN 14423 / DIN 2826 are serrated and are physically longer, larger and stronger. Due to the high temperature applications in which steam couplings are used, PTFE or novatec® PREMIUM II thread seals are used for the female threaded-couplings.

For saturated steam and hot water applications.

N.B.: Steam is dangerous. Never use quick-release couplings for steam

applications. Extra care and attention should be taken when choosing the

correct hose, fitting and clamping solution.

WORKING PRESSURE: Working pressure: 18 bar / 261 psi with a temperature of

210°C / 410°F Test pressure: 90 bar / 1305 psi Burst pressure: 180 bar / 2611 psi

TEMPERATURE: Saturated steam: +210°C / 410 °F; Hot water: +120°C / 248°F

Hose, coupling, assembly method and seal must be chosen in relation with the desired application and temperature range.
