Pressure drum |
Since
1991, the starline®2000 technology developed by Karl
Weiss in 1990, has been successfully used to rehabilitate more than
250 miles of natural gas distribution mains with diameters of 4" to
24" in Europe. By using a mobile pressure drum, pipelines can be rehabilitated
which are not easily accessible to rehabilitation vehicles. After
the lining process has been completed, which takes approximately 1
hour for sections up to 1,000 feet, |
| |
|
|
the pressure drum can be disconnected from the line so that additional sections
can be rehabilitated with a single set of installation equipement in one
working day. The specially developed cleaning technique allows the fabric
hose to be uniformly bonded to the interior wall of the pipe, insuring the
high quality of the rehabiliation. For linings in operating pressures of
up to 90 psi, a cold-hardening and a warm-hardening adhesive system are
available. |
|
| Cold-hardening
system: |
The
lines are cured overnight so that the pipeline can be put into operation
again within 1½ working days. |
| Warm-hardening
system: |
Only
a few hours are required for warm-hardening so that the customer can
be resupplied with gas within 12 - 16 hours. |
|
|
| The
high quality of the starline®2000 technology, its cost-effectiveness,
long operating life, absolutely high reliability and safety as well as its
easy handling make it perhaps the most efficient rehabilitation technology
available on the market. |
