Specifications
Each contained piping system shall consist of Xirtec®140 PVC primary piping system supported within a Xirtec®140 PVC secondary containment housing. Carrier fitting sizes 1/2″ through 4″ will use Centra-Lok [the U.S. Patent No. 5,398,973] molded supports minimizing the number of fields (factory assembled) fitting joints.
Carrier sizes 6″ and larger will use IPEX standard polypropylene fitting discs to support and centralize. Each system shall be provided with suitable drains and vents and designed to provide complete drainage of the primary and secondary containment piping.
Interstitial supporting devices shall be made from Polypropylene Centra-Guide supports and shall be provided within the secondary containment pipe, and shall be designed to allow continuous drainage in the annular space to the drain points.
Drain fittings shall be designed to allow a valve attachment to be made so that the secondary containment compartment may be readily drained and manually checked for leaks.
