Abstract
An integrity monitoring system for a lined pipeline is provided for monitoring the integrity of a polymer liner in a host pipe. Methods and apparatus are described by which a lined pipeline is provided with such an integrity monitoring system. Sensor cable is able to bridge a joint between sections of lined pipe, for example by routing the sensor cable across the joint via a channel in an electrofusion fitting or by connecting successive lengths of sensor cable via pass-throughs in an electrofusion fitting. Advantageously, the sensor cable is disposed within a continuous annulus between linings and host pipes, and the continuous annulus is maintained across pipe joints using electrofusion fittings.
Claims15
An electrofusion fitting for joining a first internal pipe lining of a first section of lined pipe to a second internal pipe lining of a second section of lined pipe, the electrofusion fitting being configured to be received in respective ends of the first and second sections of lined pipe, and to enable a first sensor cable portion disposed between the first internal pipe lining and a first host pipe in the first section of lined pipe to communicate with a second sensor cable portion disposed between the second internal pipe lining and a second host pipe in the second section of lined pipe, the first and second host pipes each being of metal.
