However, EPC-S (Electrical and Mechanical Insurance Framework) is a composite material consisting of special polyethylene strips and an adhesive film. It is used to give extra mechanical assurance to directing wires while welding. EPC-S is applied along the length of the welded region, giving a defensive boundary against mechanical elements and outside harm.

Both Polyband and EPC-S provide durable corrosion protection and offer increased mechanical strength in the weld area. They help to prevent leakage, moisture ingress and protect conducting wires against harmful chemical and physical agents. Their proper application ensures a longer life of the pipes and reduces the need for frequent repairs and replacements.
