Expansion Joints

JP124 Articulated Expansion Joint Flanged

Specification

Double hinged articulated expansion joint consisting of two stainless steel grade 321 bellows welded to carbon steel centre tube fitted with carbon steel oval flanges and hinge assembly drilled to BS4504 PN16

Application

Stourflex double hinged articulated expansion joints are generally installed in changes in pipework direction and will accommodate lateral movement in only one plane. This movement occurs due to thermal expansion or contraction or building settlement. Due to their construction they are particularly suitable where large movements or high operating pressures are involved. They are suitable for use on L.T.H.W., M.T.H.W.,H.T.H.W., steam and other hot liquids or gases.

• Maximum working temperature 300ºC.
• Maximum working pressure 16 bar at 120ºC.
• Stourflex articulated expansion joints should not be used at both their maximum working temperature and pressure respectively.
• Maximum test pressure = 1.5 x working pressure or 1.5 x flange rating whichever the lower.
