Casing Filler
Polyisobutene‑based filler pumped hot into the annulus between a casing pipe and the carrier pipe, for example at road, rail and waterway crossings. As it cools it sets into a flexible mass that displaces water and oxygen, so corrosion cannot start. Compatible with cathodic protection.
