Aggressive Produced Water Service

LPS first approached the client while they were in the middle of testing competitor sleeves due to joint failures related to the epoxy caulk that is required to help seal each side of the sleeve.

In side by side tests on 12 inch pipe, it was decided that FlexSleeve was the superior product due to the ease of insertion, better heat resistance, and a better sealing system that did not require epoxy caulking.

The client contracted LPS to provide FlexSleeves for trial in a produced water pipeline. One FlexSleeve was welded into a pipe spool immediately after a 90 deg. elbow that is connected to a pump. The water flow at this location is highly turbulent. The turbulence, corrosive water at elevated temperature, and relatively high pressure are all putting FlexSleeve to the test.

The sleeve was video inspected after 4.5 months of service, showing the seals and coating intact. No adverse issues reported and the spool was returned to service.
