Appendix E – Problem 8
E.8 Consider a pipeline system that is protected by large compressor surge tanks (Figure 5.25) that do not allow pressures anywhere along the pipeline to drop below +10m even during extreme surge events.
As air valves were not considered to be part of the surge protection system, the utility was debating whether to slash the air valves maintenance budget and sought your input.
Provide your recommendation along with a detailed description of the necessity (or otherwise) of the air valve maintenance program.
