The possibility for permanent monitoring opens the road for plastic pipes in new high sensible and demanding applications.

Therefore new applications are conquered by intelligent pipe structures and establish new markets.

In the light of the findings – and subsequent analysis and evaluation of the observed data – this report has reached the following key conclusions about the relative merits of the different sewer pipe types currently available: In service, flexible pipes perform better than rigid pipes, Buried pipelines need flexibility, Fittings for flexible pipeline systems ensure more reliable connections, Installation of flexible pipeline systems reduces risk to the environment, Flexible sewer pipelines are the sound, long-service option.

The comparison of the R-curves obtained from the two types of specimens (with and without a protective layer) indicates that both are practically identical.

To improve the interfacial interaction between the reinforcement and the pipe, polyethylene yarns were fabricated by a micro-braiding technique for use as the reinforcement.

This pipe showed excellent long-term creep strength compared with the PE80 gas pipe or pipes reinforced with other kinds of resin.

Organic pigments broaden possible application areas for rework and reduce disposal issues as well.

We have developed an inorganic material based on synthetic amorphous silicon dioxide withan average primary particle size of 150 nm and a specific surface area of 20 m2/g, called SIDISTAR Every one knows that plastic is a fantastic material in a fault and rain water application field.

There are lots of advantages in use of plastics: very good hydraulics (low material roughness), no incrustation (no sediment / sludge influence on a pipe surface), tightness of connections, durable materials / long life of a system, chemical resistance, light weight, ease of installation.

The results of the technology development satisfied the development targets.

But because the devices and joints are prototypes, it will be necessary to re-evaluate the reliability, dependability, durability, environmental and site applicability of each technology using final products intended for sale.
