Liners, Preliners + Calibration Hoses

The Trelleborg MultiFlex Liner is the unbeatable choice when it comes to rehabilitating vertical and horizontal pipes in small diameters ranging from DN30 to DN100. If there are no special requirements regarding the wall thickness of the laminate, it can also be used in base pipes with diameters up to 200 mm. The highly flexible material ensures easy installation and the best possible lining with several bends of up to 90° and up to two changes in dimension.

• DN30 – DN200 / NPS 1,18"– 8"
• ≥ 3 mm final wall thickness
• PU-Coating
• Suitable for all known curing methods

Whether vertical or horizontal pipes, it always reliably achieves a minimum wall thickness of 3 mm, even with multiple 90° bends and/or dimensional changes, and is characterized by its excellent, calculable longitudinal expansion.

• DN70 – DN250 / NPS 2,75” – 10”
• ≥ 3.5 – 5.0 mm final wall thickness
• TPU or silicone coating
• Suitable for ambient, hot and steam curing

Ideal for professionally executed standard installations for house connections and in building services.

• DN100 – DN600 / NPS 4” – 24”
• High coating elasticity
• Suitable for bends up to 45°
• Excellent impregnation properties
• Available with different end wall thicknesses
• Suitable for ambient, hot and steam curing

Thermoliner Stretch is the perfect product for rehabilitating sections with up to two dimensional changes and several bends. The special, multi-layer substrate material allows the liner to be overfilled with resin, ensuring that a final wall thickness of > 3 mm can be reliably achieved even at the maximum dimension (150% of the initial diameter).

• DN70–DN250/NPS 2,75”–10”
• ≥ 3.5 – 8.0 mm final wall thickness
• PU-Coating
• Suitable for all known curing methods

Thermoliner Stretch SL is the perfect product for rehabilitating sections with up to two dimensional changes and several bends of up to 90°. The special substrate also allows the liner to be overfilled with resin, which means that excellent final wall thicknesses can be achieved in the dimensional changes if required.

• DN70 – DN150 / NPS 2,75” – 6”
• ≥ 3.5 – 5.0 mm final wall thickness
• PU-Coating
• Suitable for all known curing methods

Thermoliner Plus is the product for the renovation of straight sections with a maximum of one dimension change and bends up to 45°. Its PES felt carrier material has good longitudinal tensile strength, which favors precise installation when installed with an open end.

• DN70 – DN300 / NPS 2,75”– 12”
• ≥ 3.5 mm final wall thickness
• PU-Coating
• Suitable for all known curing methods
• UV-HG / LED-curing only with butt seam

Glassfiber reinforced liner

If you are looking for a competitive liner which ensures high mechanical properties for both gravity and pressure pipe renovation, the Trelleborg HybridLiner is the best solution.

The composite of woven chemically resistant (ECR) glass fiber layers and polyester needle fleece, with a PP-coating on one side, provides this liner with outstanding stability. Yet with the flexibility to handle bends up to 45 degrees.

• For gravity and pressure pipes
• Available diameters DN 150 – 600 mm (6 – 24 inches)
• Other dimensions can be manufactured upon request.
• Appropriate for hot water or steam cure up to 110 °C /230 °F

Cost-efficient liner for project business

Trelleborg MainLiner is the best choice when you need a customized solution. It is coated with an elastic polypropylene-coating, which varies from flexible to robust, in correlation to the tube diameter. This gives the liner optimal processing properties adapted to the respective area of application.

• For longer, straight CIPP lining
• Available diameters DN 150 - 1600 (6" - 63")
• Appropriate for ambient, hot water and steam cure and many resin type
