CustomGuard® Custom-Designed and Fabricated Systems

Custom-designed and fabricated double containment systems include a variety of different material choices.

  • Custom designed and fabricated
  • Cost-effective custom solutions
  • Fabrication of preassembled pieces to minimize install time and field joints

For applications whose mechanical, chemical or thermal requirements cannot be met by one of our off-the-shelf solutions, our double containment specialists will build a unique system to meet your performance specifications – considering chemical compatibility, cost of materials and installation, life expectancy and turnaround time.

Drawing on more than 15 years of double containment experience, IPEX has developed a variety of product-specific designs that result in a more cost-effective custom solution. And every CustomGuard system is backed by a range of support services unmatched by any other supplier.



For applications with more demanding mechanical, chemical and/or thermal requirements, IPEX has developed our CustomGuard offering. CustomGuard includes a variety of different system choices ranging from Fluoropolymers (e.g. PVDF), Thermosets (FRP); and carbon and stainless steel to hybrid combinations. Applications that require such materials are obviously complex, each demanding expertise and specialized knowledge to design an effective system. The CustomGuard option includes material selection, design, specification support (if needed) and fabrication of preassembled spooled pieces to minimize installation time and field joints.

Available in 1/2”-20” carrier and 2”-26” containment sizes.

This comprehensive offering, unmatched by any one company, gives IPEX the unique ability to examine just about any double containment requirement and truly offer the best suited, most cost-effective system. While other manufacturers have vested interests in recommending their one and only material/system, IPEX isn’t confined by that limitation.


Drawing on more than 15 years of experience in double containment, IPEX has developed a variety of product-specific designs to maximize efficiency and reduce installation costs. As with all our containment systems, our own patented Centra- Guard™ point-of-collection or cable leak detection systems are also available.


Each contained piping system shall consist of Schedule 40 A-53 Carbon Steel primary piping system supported within a UL FRP secondary containment housing. Each system shall be provided with suitable drains and vents and be designed to provide complete drainage of both 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.
