Mechanical joints absorb thermal expansion
Victaulic flexible grooved couplings for pipework have the inherent capability of accommodating linear movement and angular deflection and can be used as a cost-effective maintenance-free alternative to accommodate thermal movement. The EDPM gaskets used in Victaulic couplings and withstand the flow temperatures commonly used in district-heating systems — 90 to 95°C.
Another benefit of such couplings is the provision of a union at every joint.
