7、ced expansion joints shall be formed by one of the methods described in the EJMA Standards. They shall be provided with reinforcing or equalizing rings. Reinforcing rings, which support the root of the corrugation under internal pressure, are solid or tubular in cross section. Equalizing rings, whic
8、h support the root and sidewalls of the corrugation under internal pressure are usually “T” shaped in cross section. Equalizing rings, sometimes called control rings, have diameters larger than the outside diameter of the corrugation and limit the maximum compression of each corrugation. The classif
9、ication of the expansion joints covered under this specification sheet are as follows: Type II - shall be provided with reinforcing rings or equalizing rings. Class 1 - shall have a single bellows. Type II joints designed for the absorption of axial movement shall, when required, be provided with su
