Canusa SuperStop - CSS

End cap to seal pre-insulated pipe ends

The Canusa SuperStop - CSS is a heat shrinkable, end cap for pre-insulated pipes (example: district heating pipes). The CSS is made from a specially formulated crosslinked polymer combined with a high temperature adhesive providing a high quality, reliable system for the sealing protection of pre-insulated pipes.

Watertight Seal

The Canusa SuperStop - CSS is designed to provide a watertight seal and prevent water access to the exposed insulation at the weld joint area. Upon application of heat, the CSS shrinks to conform to the profile of the insulated pipe, while the adhesive simultaneously “melts” to bond to the jacket casing and the service pipe. To ensure overall protection of the insulating foam, CSS should be used on both pipe ends.

Insulation Protection

The Canusa SuperStop - CSS can be factory-installed on the pre-insulated pipe. Once installed, the CSS protects the insulation during transportation and storage. During service, the CSS prevents water ingress into the insulation in the event of leakage at the joint. If there is a leakage within a pipe length, the CSS limits the insulation degradation to one pipe length. This can greatly reduce repair costs.

Large Size Range

The Canusa SuperStop - CSS is available in a full range of sizes to fit most pipe/casing combinations. Since the CSS is heat shrinkable, one size can be used to cover several casing pipe/service pipe combinations.

Easy Installation

The Canusa SuperStop - CSS is quick and easy to install. Upon application of heat the product quickly conforms to cover the pipe ends. The CSS comes with pre-applied adhesive which reduces the installation time.
