Pipework System Notes
Hinge hardware is attached to contain pressure thrust forces, and in many cases could support the dead weight of the
adjacent pipework.
Heavy expensive main anchors are usually not required.
Single hinged joints are generally used in pairs with connecting pipework between, to act in unison to absorb large amounts of lateral movement at high pressures with minimum guiding requirements and very low stresses on attached piping.
RADCOFLEX recommends you consult your pipework engineer on pipework design and expansion joint selection.
Full technical specification booklets are available from RADCOFLEX to assist.
