The fuel line was closed down and a decision was made to replace the length of pipeline with a new line. The new line was to primarily run above ground for ease of maintenance but needed to accommodate three below ground sections to facilitate road crossings. Following design approval and receipt of development approval from KPA the works commenced on site and took 6 weeks for Melchor Contracting to complete.
The new pipe was 200mm diameter supplied in 12m lengths and joints welded on site. The pipe was supported on steel brackets cast into insitu concrete footings with Teflon spacers to provide cathodic protection. Below ground pipes were protected with two layers of denso tape. Armco barriers were installed in front of the pipe where it was vulnerable to potential traffic impact. The completed pipe was commissioned following a successful pressure testing witnessed by an independent testing authority.
