Casing Filler

Stopaq Casing Filler is the most effective solution for preventing corrosion of steel pipelines in steel casings. Water and oxygen that normally is expected to be present in a non-filled casing pipe, will cause corrosion of the operational steel pipeline and also will cause internal corrosion of the casing pipe. By filling the annulus between the casing pipe and the operational pipe with Stopaq® Casing Filler, water and oxygen will be displaced, thereby ruling out corrosion. Stopaq® Casing Filler is delivered to the casing job site by truck in a heated tank and pumped down the casing vent as a hot liquid. As it cools down, it firms up to a pasty consistency. The product does not cure or become brittle, it stays flexible forever and maintains its optimum sealing properties.

Once applied, Stopaq® Casing Filler will also prevent eventually present Cathodic Protection currents to cause internal corrosion of the casing pipe. The material has high specific electrical insulation resistance which prevents passing of electrical currents. Superior end-sealing solutions are applied in combination with Stopaq® Casing Filler. This will prevent the ingress of water, oxygen and soil from the casing pipe ends. The solution is by far superior to other casing filling solutions on the market. It combines excellent corrosion preventing properties and visco-elastic behaviour of Stopaq® materials.
