DUALTEC pipes
Double-layer pipe with protective casing | Pricelist
DUALTEC is a pipe made of high-density polyethylene HDPE 100+ with protective casing of polypropylene. It is resistant to abrasion, scratches and other types of mechanical damage. The casing
thickness is fully sufficient for perfect protection of the pipe. The pipe ends do not need to be cleaned for welding, only the required part of the protective casing is to be peeled off right before welding.
We currently make the pipes at the size of 32 - 110 mm, however, we assume that we will expand our assortment with 160 and 225 mm as from the second half of 2007.
Products are approved for use in Czech Republic (certificate).
Possible aplications
- water pipes (blue protective casing)
- water pipes (blue protective casing)
- pressure sewage pipes (brown protective casing)
Use
- for laying in trench (the trench can be covered up with the excavated soil with the grain size up to 63 mm, it should not be frozen and should not contain sharp-edged materials)
- for trenchless laying (especially where the pipes can be damaged by unfavorable conditions = no need of special protectors, etc.)
- controlled micro-tunneling method
- pipebursting
- relining
- plowing

Advantages
- permanent protection of inner tube against damage during the pipe transportation, storage, handling and laying
- more efficient and rational pipe laying with the use of the trenchless technology
- no more costs of the excavated soil disposition and testing (to be re-used), no need of delivering special filling materials
- no need of time-consuming cleaning for welding and scraping the oxidized layer when the protective casing is peeled off right before welding
- it is an environment-friendly product, recyclable and harmless to health (for drinking water distribution systems, etc.)
- the pipes feature low specific weight, chemical resistance and resistance to corrosion
- the minimum lifecycle of this pipe is 50 years
