  1. Requirement on a CIPP-System

  2. Advantages in general Excellent stretching behavior Low loss of diameter Short installatoin time Good mechanical qualities 50 years service life Ready to install Low shrinkage Smooth inner surface Chemical resistance Installations length as long as possible Long storage time Quality controlled production

  3. Advantages of elements Inner film, outer film, rope, impreg- nation Ready to install Should be done in factory Short installation time Thickener Long storage time Viscosity, curing system, resin Chemical resistance UV-light Length of liner as long as possible Polyester, Vinylester Low shrinkage Reinforce- ment Glass fiber Low loss of diameter Overlapping zone Good mechanical qualities Layer construction Excellent stretching behavior

  4. Advantages Viscosity of resin Thickener Long storage time Viscosity change with different dosages • During impregnation low viscosity • After impregnation an optimal level If level will become to high expansion is handicapped. If level is to low resin starts flowing.

  5. Curing System Curing system UV-light Short installation time • Fast curing speed up to 600 mm/min • (depends on wall thickness and light source). • Liner installation without overtime possible. • No unnecessary hindrance to traffic in towns, • air traffic at airports, material flow in industrial • plants.

  6. Curing System Reinforcement UV-light Long storage time • Curing is independent of temperature (exclusively • started by UV radiation). • Changes of the time shedule have no influence of • quality (within 6 month after manufacturing). • Simple logistic. • No cooling transport required.

  7. Reinforcement by glass fiber Diameter 300 mm, wall thickness 5 mm, max. pulling force: 234 kN (4,643 m) Length of liner as long as possible Low shrinkage 0,5 % E.g. diameter of 600 mm, SN 10.000: Wall thickness - glass fiber reinf. 13,5 mm, Wall thickness – Polyester Felt ~ 20 mm Low loss of diameter Ring modulus > 10.000 N/mm2 (for comparison purpose: Polyester Felt < 3.000 N/mm2) Good mechanical qualities

  8. Properties Excellent stretching behavoir Overlapping zone Layer construction Woven roving Chopped strand mat

  9. Properties Good mechanical qualities Overlapping zone Layer construction Diameter change from 450 mm to 500 mm
