COUPLING
PROPERTIES

Glass reinforced plastic pipes are attached with pressure and non-pressurized lines and with coupling connection system which provides precise sealing. Couplings are produced using the same raw materials and the same process technique as Standard GRP pipes. Connection sleeves produced from GRP pipes are processed in sleeve manufacturing machine and slots are opened according to EPDM REKA seal and stopper tolerances. Esen Plastik EPDM seals provide double sided sealing with its special structure.

Coupling

ESEN GRP couplings are produced using the same raw materials and same production technique as GRP Pipes. The sealing grooves of the produced couplings are opened with full dimension tolerances in fully automatic machines and the elastomeric EPDM REKA seals are installed to ensure precise sealing. Esen GRP sleeves allow perfect angular deviations in the laying stage with excellent dimension and working tolerance range. These angular deviations are as follow.

Esen Elastomeric EPDM REKA seals provide safer installation simplicity compared to others and provide absolute water tightness even at high pressures

Compared to other couplings manufactured with different machines and different production techniques, ESEN GRP Couplings provide easier and safer installation in all weather conditions and all kinds of ground conditions. Compared to other systems, ESEN GRP Couplings have the same flexural properties as the pipes.

The cross section of the Esen GRP Coupling is as shown in the picture above before pressure is applied to the pipeline.

You can see the cross section of the Esen GRP Coupling and the state of the pipeline after the pressure is applied in the picture above.

Elastomeric Epdm Reka Seals; with excellent dimension tolerance, the sealing ring is pressed against the sleeve wall. The stopper part located between the two seals prevents the ends of the two pipes from hitting each other during damage.
