As a manufacturer, POliner may change product specifications without notice.
POliner Hydro series products are CIPP liners dedicated for trenchless rehabilitation of water supply pipelines. They can also be used in industrial pipelines and pressure sewage systems. The liners are impregnated with special styrene-free resins – polyester or vinyl ester or epoxy depending on the needs. Every product has been given the certificate of the Polish National Institute of Hygiene, which proves it is safe for use in systems supplying potable water.
CIPP POliner Hydro liners offer higher flexibility after curing (in comparison with liners impregnated with styrene resins). This gives a better fit of the new liner with the host pipe and ensures resistance to pressure surges.
Given the diverse range of combimats and resins at our disposal, we create liners perfectly tailored to customer needs.
POliner Hydro products, depending on their function, are divided into:
– construction liners, which include: POliner Hydro Glass, POliner Hydro Felt, POliner Hydro Felt & Glass;
– sealing liner: POliner Hydro Seal.
Application: pressure water supply systems, pressure sewage systems, industrial pipelines
POliner Hydro Glass
A CIPP liner made of highest quality glass fiber having a layer of fabric with an integrated internal membrane that serves as a barrier between the transported medium and the composite, ensuring additional tightness of the pipe. The liner is impregnated with a styrene-free polyester resin.
The initiation of the co-polymerization process is carried out by exposing the composite to UV or UV-LED light, or thermally.
Diameter range: DN150 – DN1200
POliner Hydro Felt
A CIPP liner made of felt-structure nonwoven polyester fabric with a thermoplastic coating which after the inversion process serves as the internal membrane. An additional layer comes from a seamless polyester weave for increased resistance to internal pressure. The liner is impregnated with a styrene-free polyester resin or vinyl ester resin or epoxy resin (on site of the installation).
The initiation of the co-polymerization process is carried out thermally.
Diameter range: DN150 – DN600 (epoxy resin impregnated)
DN150 – DN1200 (polyester resin or vinyl ester resin)
POliner Hydro Felt & Glass
A CIPP liner made of felt-structure nonwoven polyester fabric with added reinforcement made of a layer of high quality fiber glass. The liner has a thermoplastic coating which after the inversion process serves as the internal membrane. The liner is impregnated with styrene-free polyester resin or vinyl ester resin or epoxy resin (on site of the installation).
The initiation of the co-polymerization process is carried out thermally.
Diameter range: DN300 – DN1200.
POliner Hydro Seal
A sealing CIPP liner made of seamless weave polyester fabric with a thermoplastic coating which after the inversion process serves as the internal membrane. The use of such a liner ensures full tightness and improvement of hydraulic performance. The liner is impregnated in styrene-free epoxy resin (on site of the installation).
The initiation of the co-polymerization process is carried out thermally.
Diameter range: DN150 – DN400.
