Rehabilitation of gas pipelines
starline® technology is used for the rehabilitation of gas pipelines up to DN 600 (DN 1200 with special equipment) and operating pressures of up to 30 bars, to sustainably restore the necessary operating safety. The rehabilitated pipeline can then be considered as a new pipe and can be commercially fully activated, i.e. the value can be depreciated over its useful life.
For the following applications of gas pipe renovation we have developed special fabric hoses, adhesives and specially designed technical equipment:
- starline®HPL-G: for the rehabilitation of high pressure pipelines
- starline®2000: for the rehabilitation of utilities pipelines
- starline®200: for the rehabilitation of mains connections
The key stages of pipe rehabilitation using this process are the inspection of the pipeline with a camera, thorough cleaning, lining with the starline® fabric hose, pressure testing of the reconditioned pipeline and if necessary using a robot to open outlets and connections from inside the pipeline.
Incidentally: future maintenance and repair work can be carried out using everyday tools and requires no special parts.
