Guardian™ PVC & CPVC
Pressure & drainage double containment systems
Guardian™ systems have been the benchmark in thermoplastic double containment for more than 25 years. Offered in both Xirtec® PVC and high-temperature Xirtec® CPVC made with Corzan®, the result is a superior system that is unmatched for safety and reliability.
The Guardian™ system’s patented modular components are pretested and extremely easy to install, resulting in a reduced number of joints, installation, maintenance, and repair costs. These systems are used in industrial applications such as:
- Wastewater Treatment
- Chemical Process Industry
- Server Rooms
- Pharmaceutical Industry
- Food and Beverage
features & benefits
- Patented Centra-Lock™ design reduces the required joints by 40 – 60%
- Reduced joints mean reduced failures and leaks
- Centra-Lock™ design allows for convenient and quick simultaneous solvent weld fusion
- Available in tough industrial grade PVC and CPVC
- Instant leak detection of overhead piping use
The specification section covers the details you need for your projects.
|Xirtec® PVC||1/2″ – 12″||2″ – 18″|
|Xirtec® CPVC||1/2″ – 12″||2″ – 18″|
|Clear-Guard™ PVC||n/a||2″ – 8″|
*Larger sizes are available upon request
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.
Xirtec® 140 PVC and Corzan® CPVC are used for the Guardian™ systems.
Clear-Guard™ can be used in conjunction with both Schedule 40 and 80 PVC or Xirtec® CPVC primary pipe.
