Extruded TPU Lay Flat Hose for Pipe Rehabilitation

  • Specially Designed for Drinking Water Transfer in Trenchless Pipe Network Repair
  • Premium & Flexible Leak Free Hose Adaptable to the Pipe Nominal Diameter
  • Total Corrosion Resistance Ease of Transportation and Handling
  • Fully Approved for Potable Water - NSF/ANSI/CAN Standard 61 Certified - BS 6920:2014 Compliant


Blue cover is the standard. Other colours are available upon request.


Designed for water pipe network rehabilitation. This thermoplastic polyurethane (TPU) coated hose is manufactured in diameters ranging from 4” (DN125) to 20” (DN500). Its ease of expansion helps to adapt perfectly to the internal walls of the pipe to be repaired, providing an excellent wear resistance and an outstanding resistance to hydrolysis and microbiological attack.


Made from circularly woven 100% high tenacity synthetic yarn, completely protected and locked- in by a tough, highly resistant thermoplastic polyurethane extruded through the weave, forming a single homogenous construction without the use of glues or adhesives. Its construction does not permit corrosion or scaling, while giving a high resistance against abrasion and cutting. Easy handling, storage & transport, which allows for fast installation. 2% maximum hose elongation and 10% maximum hose expansion.

Abrasion Resistance:

The OROFLEX RELINE hose will extend the life- time of your application when under extreme conditions, where abrasion is the main concern. Under practical conditions, thermoplastic polyurethane is considered to be the most abrasion resistant elastomeric material.

Lining Properties:

a. Ultimate Tensile Strength of the lining: Mini- mum guaranteed value of 5,800 psi (40 MPa).
b. Ultimate Elongation: 500% minimum

Service Temperature Range:

From -58°F (-50°C) to 150°F (65°C), with peaks of up to 175°F (80°C). Special versions for higher and lower temperatures available upon request.

Structural Strength:

The OROFLEX RELINE hose ensures continuous water supply even if the main pipe breaks.

Chemical Resistance:

Exposure to seawater and contamination by most chemical substances, hydrocarbons, oils and greases has no effect on the short or long term performance of the hose. A chemical resis- tance chart is available and TIPSA will supply spe- cific chemical resistance data when requested for unique applications.

Recommended Operating PH Range:

4 to 9 below 86°F (30°C) and 5 to 9 from 86°F to 122°F (from 30°C to 50°C).


Standard lengths in 660ft (200m). Longer lengths may be available according to project needs.
