Sewage expansion joints are manufactured according to the following standards:
INSO 9119-1 and EN 1329-1
An expansion joint is actually a type of connection that is used in a building’s sewage drainage system to create flexibility. The use of an expansion joint, given that one end is connected as a push-fit (O-ring) and the other end is connected as an adhesive, prevents damage to the sewage system, damage caused by longitudinal expansion or various impulses that enter the sewage system.
