Pipeline isolation for the 21st century

摘要

Angus Bowie, Regional Director for the Middle East & Asia Pacific at STATS Group, explains how the pipeline industry has turned a corner when it comes to utilising hot tap isolation. When STATS first investigated hot tap isolation back in 2005, it was discovered that the existing technology was based on equipment which had not changed since the 1950s and did not meet current standards. There was a single high-pressure lip seal with an acceptable leak-rate, an open vent and a low pressure gas bag to hopefully divert the lip-seal leak to the open vent.
