Abstract
The integrity of corrosion prevention sheaths of corrosive-resistant metal employed to prevent member corrosion on off-shore platforms is monitored by incorporation of a pressure sensing line sealed into the zone between the sheath and the member. This apparatus allows monitoring members in the splash zone as well as stressed areas such as weld joints which are subject to corrosive environments.
