This vinyl double containment piping system is fast and easy to install, and is available with a complete selection of pipe, fittings, and valves. Double-See® is available in PVC and CPVC; either material may be primary or secondary (PVC x PVC, CPVC x PVC, CPVC x CPVC) with Clear PVC always being an option for the containment pipe. Installation versatility allows simultaneous joining throughout a system or in combination with patented closure couplings which enable practical compliance with the ASME B31.3 requirement for visual inspection of all primary joint connections during the pressure test before closing the secondary piping joint.

The installation versatility of Double-See allows for simultaneous jointing throughout a system or in combination with patented closure couplings. These enable practical compliance with ASME B31.3 Code requirements.
A large selection of standard components is available. Additionally the Double-See™ system is also available with custom designed spools and leak detection options.
An innovative centering design compensates for thermal expansion. This allows Double-See to be used in both aboveground and underground installations.
Double-See pipes and fittings are 100% factory-assembled. They offer GF quality as well as field and factory engineering support.
GF SmartPro transmitters and Multi-Parameter controller are available for your process applications: The 9900 is a single-channel transmitter available as a panel or field mount, whilst the 9950 two-channel controller supports two sensors of same or different types in one instrument.
Sturdy and lightweight, plastic pipes are ideal for use in a wide range of applications. Versatile yet durable, these all-rounders offer exceptional reliability and proven quality.
Bends and elbows are essential fittings that easily change the direction of pipes. The extensive range available offers not only multiple materials but also different curvature degrees to easily fit your piping system.
Simplify the pipe installation process with couplers and sockets. Specially designed to slide easily over pipes with no extra equipment required, they are cemented, welded or mechanically connected to create a pressure-tight joint.
When creating branch lines, lightweight tee, wye, and cross fittings make installation much easier. These fittings are made from a range of materials and malleable iron and cover multiple dimension possibilities including various reductions on the same fitting.
With GF Piping Systems boxes, pipes can be replaced easily without damaging the wall thanks to the flexible box feet.
Termination fittings represent the beginning and the end of a double containment system and seal the monitoring room. For complex isometrics, end fittings are used to segment the monitoring room.
The new generation with standard lockable lever, data matrix code and modular design guarantees long-term sustainability. The Ball Valve 546 Pro meets every challenge and application, including simple water applications or complicated processes in the chemical industry, microelectronics or food and beverage industry.
Designed for stress-free installation with minimal movement during the welding and cooling process, these tools can be clamped into position with ease. The GF Piping Systems range includes multiple innovative variants for maximum practicality.
