High Performance Fabric In Old Piping: Quick, Durable Restoration Of Operational Safety
In consideration of all general conditions and with respect to the available financial means, it is suggested that the pipe be restored with woven fabric relining. In this process, a woven fabric liner coated in plastic is soaked at first. Reversion by means of compressed air then takes place within the pipe being restored. At the same time, the wetted adhesive side of the woven fabric liner is upside down and holohedrally stuck on to the inside of the pipe that was cleaned earlier (Fig 1 + 2). Reliable connections or outlets will be opened from the inside in advance by robots. As a result, heavy costs for underground work will be kept to a minimum. New connections can be connected without problems and sealed against exfiltration in a conventional manner.
Existing and future occurrences of corrosion which represent a potentially enormous hygiene and technical safety risk in conveyor pipelines can be efficiently, quickly and sustainably repaired. Thereby, the required safety standard is permanently restored and additionally, a minimization in the risk of weld seam breaks is achieved. Woven fabric relining enables the target state of the available pipe to be restored. This is achieved with the following features:
- Sealing of all present and future leaks therefore increasing or restoring necessary operational safety;
- Restoration of necessary hygiene;
- Precautionary corrosion protection against inner corrosion;
- Retaining the dimension of the available pipe and prevention of future incrustations;
- Preventive sealing of vulnerable weld seams;
- Application on places that are difficult to reach, on crossings, in ecologically sensitive areas, on stony grounds etc.;
- Reduction of problems with access rights and reduction of work in confined cramped conditions; and
- Economy through sustainability because woven fabric relining is classed as being a depreciable service due to a material life span of at least 50 years.
