(CIP) pipe liners are intended to rehabilitate structurally sound
pipelines having localized defects such as localized corrosion,
welds that are weaker than required for service, or loose joints
(cast-iron pipe), where leaks might occur. In the starline®
technology, a seamless circular-woven fabric hose made of polyester
fabric with a plastic coating is inserted into the pipe to be lined
by the inversion process, and is uniformly glued to the interior
wall of the pipe with a solvent-free two-component adhesive.
primary benefits of the technology are:
- The flexible
liner can be installed even in pipes with bends to seal against
- Even if the
pipe is broken by third party damage or ground movement, the starline
fabric hose remains gas-tight, i.e. safe operation is insured.
- CIP Lining
does not significantly reduce pipe capacity.
of pipe requires minimal excavation and restoration.
- The gas
cannot migrate due to the fact that the liner uniformly bonds
to the pipe.
pipeline maintenance procedures, including installation of new
services, can be performed after starline® has
been installed in the pipeline. All pipeline works required on
rehabilitated pipes can be performed using conventional pipeline
construction methods, i.e. no special tooling or fittings are
- CIP liners
have been proven to be a long-term solution to leaking pipes with
an operating lifetime that exceeds many decades, provided that
the statics of the host pipe is not weakened.
