The pipe-in-pipe system for drinking water installations

JRG Sanipex is the world's first plastic pipe-in-pipe drinking water installation system. For more than 40 years, the pioneering JRG Sanipex system has been continuously adapted to the needs of the market. The cone grip union technology guarantees safe, water pocket-free connection at full flow. The pipe-in-pipe technique allows the pipes to be laid directly in the concrete and for the PE-X pipes to be replaced in the protective pipes as required.

Water damage can be avoided

The water-carrying inner pipe made of cross-linked polyethylene (PE-X) is encased in a protective conduit. This prevents water from penetrating into the building structure in case of damage. Instead, water escaping from the system flows to the distribution box, which has a warning system, and/or is discharged to the outside through the outlet in a controlled manner. 

Impeccable hygiene

The JRG Sanipex cone grip union connection guarantees a secure, water-pocket-free connection at full flow. This takes away the breeding ground on which bacteria and legionella multiply. Generally, the system makes it more difficult for biofilm to form and ensures impeccable hygiene.

Further advantages

Full pipe cross-section minimises flow noise and pressure losses

The pipe cross-section remains unchanged thanks to the connection technology. Flow noises are therefore extremely low, and pressure losses are kept to a minimum. 

Replacing the inner pipes without damaging the wall, floor or ceiling

A drinking water pipe that gets broken during construction or a leaking connection can cause expensive water damage. Thanks to the pipe-in-pipe system, the water-carrying inner pipe can be replaced without damaging walls and floors.

Smaller dimensions speed up the exchange of water

The full pipe cross-section means that pipes with smaller dimensions can be used. This saves space, requires smaller holes and reduces the cost of materials. Hardly any other system is able to offer the dimension D12, although this is usually wholly adequate for connections to the wash basin, toilet or washing machine. 

Small diameters also make sense in terms of energy. The volume of circulating water is correspondingly smaller and it takes less time for the hot water to be available at the extraction point. 

Cone grip union connection requires no additional sealing materials

Leak tightness is guaranteed in the connections. The patented cone grip union connection compensates for temperature-related changes in material thickness, hence keeping the contact pressure constant. Additional sealing material is not required – an advantage when it comes to safety.

JRG Sanipex Components

JRG Sanipex PE-X pipes

PE-X pipes

PE-X pipes consist of three-dimensionally cross-linked polyethylene. The cross-linking significantly improves creep strength, low-temperature toughness and stress-crack resistance, and thus ensures a safe supply of top-grade drinking water in your installation for decades to come.

Multilayer composite pipes

Multilayer composite pipes combine the advantages of plastic and metal. Thanks to the flexibility of plastic and the strength of metal, the pipes are ideally suited to withstand the wide range of temperatures and pressures in both cold and hot water systems.

JRG Sanipex Valve

Fittings and valves

All water-bearing valves and fittings are made of gunmetal. They are sandcasted and state-of-the-art in flow, noise reduction and hygiene. In addition, they are highly corrosion resistant.
