EP&S metal expansion joints
EP&S metal expansion joints fully comply with a number of standards and bodies which are used as a basis of assessment, including AD 2000-B13, DIN EN 14917 and EJMA. EP&S steel expansion joints possess type approvals from various classification and certifying bodies and carry the CE mark.
Accommodating thermal expansion: When used in conjunction with expert advice, all thermal expansion requirements can be accounted for using EP&S metal expansion joints. Thanks to the multi-ply make up, and the intricate design process of the metal expansion joints, a longevity and assurance is guaranteed providing they are correctly installed.
EP&S rubber expansion joints
The EP&S range of rubber expansion joints primarily fulfil the internationally renowned DIN 4809 standard for expansion joints made from elastomer composite (EPS51/52 and EPS53/58 rubber expansion joints) for water heating systems: for a maximum operating temperature of 100°C and a permitted positive operating pressure of 10 bar and a temperature of up to 110°C at 6 bar. The butyl rubber expansion joint range is fully WRAS certified and can be used on any potable water system.
Absorption of vibrations: Thanks to their optimised loose structure, the rubber materials used in these expansion joints have higher absorption capabilities than all elastomer materials available on the market and therefore offer better vibration isolation in pipelines and on system components. They therefore also have outstanding damping properties.
Noise dampening: Due to the elastic structure of the bellows, not only can structure-borne sound of pipelines be reduced but also most low-frequency liquid-borne sounds. EP&S rubber expansion joints dampen vibration transmissions in a virtually ideal way in accordance with sound protection regulation DIN 4109. Depending on the respective underlying conditions, sound-damping in regard to structure-borne sound and most low-frequency liquid-borne sounds from 10 to 30 dB in the range of 150 to 5000 Hz can be achieved by fitting a rubber expansion joint. This corresponds to a sound reduction or vibration isolation of up to 95%.
