Intelligent Pigging for Coated pipeline
Intelligent Pigging for Coated pipeline
(OP)
I am designing a 9 KM pipeline for oil and water services, this line will then be converted into an oil service only, it is a 24 inch in diameter, TK 236 material.
for maintenance purposes, sphere pigging is not recommended with coated pipe. is the intelligent pigging suitable for such pipes?
or should we plan to flush the line periodically ?

I would put connections for temporary launchers and receivers.
Permanent launchers and receivers for intel on a 9 km pipeline seems like a waste of money. Just MO.

For smart pigging, it is possible to use these on internally coated pipelines, but you have to be very careful and work with your ILI vendor. I would assume you would be running an MFL pig, these pigs have metal brushes which will scrape the coating, and also the sensors themselves will scrape the coating. The tool can be modified to remove the brushes, or use poly brushes, and also they will adjust the sensor stand off distance. If you don't let them know it is internally coated you will most likely damage your coating. An MFL pig would be more agressive to coating than a softer polyurethane maintenance pig.
