Starline Express - Model 200 -Utility Gas Pipelines
starline® 2000 and starline EXPRESS for utility pipelines. This technology uses a flexible fabric hose for the sustainable rehabilitation of grey cast iron, steel and ductile cast iron supply pipelines up to DN 600 with an operating pressure up to 4 bar. Mobile equipment is used for working in confined inner city spaces, which is unbeatable in terms of speed, economy, reliability and environmental friendliness.
Used in conjunction with our unique, state-of-the-art starline®EXPRESS fast curing technology, the interruption of the gas supply to customers is reduced to an absolute minimum. This technology is useful in particular for ordinary supply pipeline cross sections and where there is a high density of mains connections.
The sections to be rehabilitated are separated, inspected, cleaned, reconditioned and tested within one working day, outlets are opened trenchlessly and the pipeline is put back into operation. This avoids having to provide an expensive replacement supply and the necessary operating safety is permanently restored within just one day.
As the hardening of the special adhesive system occurs without the entire pipe heating up, damaging thermal residual stress in the pipe body is avoided.
