iv Double Containment Piping Systems CAUTION: Do not use or test the products in this manual with compressed air or other gases including air-over-water-boosters SECTION ONE: GENERAL INFORMATION Overview

Safety and environmental issues, such as ground water contamination, have long been serious concerns for North INFORMATION American industry. Add to this the enormous costs of litigation, clean up, and increasingly stringent corporate guidelines GENERAL and legal regulations, and the importance of fail-safe double containment systems becomes immediately clear. However, exactly what constitutes ‘double containment’? Although, on paper, simple solutions such as the lining of ditches or similar methods may appear to meet double containment requirements, in reality, they fall short. With double containment, engineers are not designing a single system or even two separate single-wall systems, but rather a combination of the two: interrelated systems, where changing conditions continually affect both primary and secondary pipes.

IPEX’s Experience By investing heavily in people and technology, IPEX has amassed more than 30 years of expertise in design and fabrication of double containment systems. In addition, IPEX is the only manufacturer of double containment systems offering all of the following: • A specialized and dedicated division dealing exclusively with double containment. • The ability to manufacture a large majority of double containment components in-house. • A variety of materials including thermoplastics, thermosets, and metallic and dissimilar systems. • Both drainage and pressure systems. • A patented system with 60% fewer joints than conventional systems. • Both off-the-shelf and custom-designed systems. • Continuous cable as well as low point-of-collection leak detection systems.

Double Containment Systems With such breadth and depth of products, IPEX offers customers proven designs that best suit their needs. Because of the large variety of systems available, it would be difficult to include all of them in one publication. Therefore this manual deals specifically with those systems most commonly used, including: • Encase™, a polypropylene piping system that uses proven Enfusion joining methods to provide an easy-to- install, safe, reliable and cost-effective method to convey chemical waste under gravity-flow conditions. • Guardian™ systems. Made from PVC and Xirtec® CPVC, these systems offer a complete selection of pre- tested modular components that are considered unmatched in the industry. Installed using its patented Centra-Lok™ design, Guardian reduces the number of joints in a system by as much as 60%. • Clear-Guard ™is a fail-safe, fully pressure rated clear containment system which allows for easy detection of leaks and eliminates the risks associated with piping aggressive chemicals overhead. Clear-Guard utilizes Guardian’s patented Centra-Lok fitting design, which reduces the required joints by 40-60% containment. Fittings are available in clear or “cost saving” opaque. • CustomGuard® systems. Together with Encase and Guardian, CustomGuard sets IPEX apart from any other double containment system. CustomGuard is available in several different materials including carbon and stainless steel, copper, fiberglass, plastics and dissimilar materials. Unlike other manufacturers, IPEX is not constrained by a limited material selection. This variety enables IPEX to provide customers with the best solution for their double containment needs. • Centra-Guard™, a low point electronic leak detection system that offers an economical pro-active solution against potential containment challenges. Its automated, trouble-free and user-friendly design guards against environmental damage and the high cost of clean up. Please contact your IPEX representative for details on all other systems not included in this manual.

When installing below-ground systems, simple precautions The trench bottom should be continuous and free of rocks should be taken. and sharp objects. Where ledge rock, hardpan or boulders are encountered, they should be padded with sand or Trench widths can be much narrower than for butt-fused compacted, friable, fine-grain soil. systems. A distance of about one foot on either side of the pipe should be allowed for access during joining.

Bedding

Firm Soil or Gravel

All free-standing water should be removed from the trench before lowering any piping into it. This will eliminate water entering the gap between the primary and secondary pipe walls, which could lead to problems when using cable leak detection systems. It will also ensure the joints remain dry. The pipe should be buried to a minimum depth of 24” from the crown of the pipe where normal foot traffic is expected. Local codes may require different burial depths and these should be strictly followed. The effects of “frost heave” should be considered when installing in ground subject to freezing. Where heavy ground traffic is expected, the pipe may require further protection, such as a greater burial depth or a structural encasement of concrete or steel. When excavating in unstable soil, the trench walls should be shored up according to local regulations. Do not lower any pipe into a trench until the walls are stabilized.

Sandbags should be placed on the trench bed at eight SYSTEM foot spacings to facilitate the temporary support of the DESIGN Shoring pipe during joining. This will also make it easier for the contractor to lay the pipe at a suitable fall for gravity flow conditions as required by the local codes. Alternatively, the trench should be lined with a 6” depth of a suitable bedding material such as sand, rock-free soft soil or 3/8” pea gravel.
