The Perfect Safe Way
To Convey Water To Cleanwater!
The proven advanced continuous filament winding technology and the benefits of composite materials enable Subor to provide solutions for pressure pipe systems up to 40 bars with a cost advantage against conventional materials.
With the benefit of Subor GRP Pipes’ structure, lower wave celerity than other piping materials mean less cost while designing for surge pressure and water hammer phenomenon.can mean less cost when designing for surge and water hammer pressures.

Standard Lengths: 6 & 12 meters
Stiffness (SN): Up to 10.000 N/m².
Custom lengths, Diameters, Pressure and Stiffness classes are available upon request.

GRP Joints
Subor GRP Pipes are assembled using the GRP coupling connection system which offers perfect leak tightness.
The GRP REKA couplings manufactured with the same technique as the GRP pipes and they are subjected to a hydrostatic pressure test following preparation in the cutting and grooving machine. Tightness of the coupling connections is provided by the gaskets made of elastomeric material. The flexibility of the gaskets allows a certain angular deviation of the couplings, thus preventing direct load on the pipe, which could result from ground subsidence and soil activity such as earthquakes.
Compared to its alternatives, Subor GRP Couplings offer fast, easy and safe installation in any ground and weather conditions.

Sleeve Couplings
In jacking applications, the sleeve couplings should have an outside diameter equal to the jacking pipe external diameter.
Couplings are available in different types and pressure classes depending on the project conditions.
EPDM gaskets are used in sleeve couplings in order to provide sealing at the joints.
Types of Sleeve Couplings:
​
-
GRP Non-Pressure Sleeve Coupling
-
GRP Pressure Sleeve Coupling
-
Steel Non-Pressure Sleeve Coupling
-
Steel Pressure Sleeve Coupling

Wall Couplings
Wall couplings are used when the GRP pipeline penetrates to masonry structures. Couplings can be covered with sand or gravel in order to increase adhesion between GRP and concrete materials.
Depending on the project needs, the wall couplings can be supplied up to 3 m length.
