Engineering use flexible limited full face sealed flanged rubber expansion joint manufacturers
Engineering use flexible limited full face sealed flanged rubber expansion joint manufacturers is rubber sealing face is fully same with flange face, it have better sealing performance. Except this point, it's same with common rubber expansion joint, it's still consist of nylon cord fabric, inner and outer rubber layer, flange is usually carbon steel galvanized, rubber is usually EPDM, of course, other material is also acceptable, such as stainless steel flange, NBR rubber, neoprene rubber etc. Working temperature is -15 ~ +120 celsius degree normally, working pressure is PN16 normally, usually end face fully sealed rubber expansion joint is mainly used for bigger size, such as above DN500 etc. About this type rubber expansion joint, we can do size range from DN40-DN3000, namely from 1.5 inches to 120 inches.
