Advance Technology Foam Seal

Casing Foaming-Hole Sealing and Protection Patch

Description:

AT Foam Seal is a heat-resistant circular sealing patch designed to protect and seal foaming holes in pre-insulated pipe-joint casings. The system combines a crosslinked polyethylene backing with a high-shear-strength adhesive to provide a durable, water-resistant seal over approved hole plugs. AT Foam Seal is supplied in a nominal diameter range of 90-100 mm for convenient field application on pre-insulated piping systems.

Features:
