Our products
- Diameter Ø150 mm to Ø1800 mm
- Ring stiffness up to SN7
- Standard Liner, adapted for the most common dimensions and SN classes
- Flex Liner, adapts itself to variations in diameter
- Special Liner, which we specially design for your challenging needs.
- UV light curing saves energy and the environment
- Two effective installation methods: inversion or winching. Read more about The installation methods.
Inpipe’s liners are constructed in several layers. On the inside and outside are foils surrounding a number of layers of corrosion resistant fibreglass-reinforced polyester.
Common areas of use
- Wastewater pipelines
- Gravity pipes
- Pressure lines
- Road and railway culverts
For pipes with an aggressive chemical environment or at abnormally high temperatures, we can offer vinyl esters.
We continuously test our liners to ensure that they fulfil the requirements set for the area of use.
All Inpipe liners are manufactured to order and completed as far as possible for installation. Everything to make it easier for you, fulfil your design requirements and reduce waste.
