FlexSleeve Wins Innovation Award for Water Pipeline

Prior to LPS becoming involved, the contractor was having personnel enter the pipe to apply an epoxy paste over the uncoated steel surface on the interior of the joint. Quality issues were a risk due to poor surface preparation and human error, and the slow process of hand-coating and inspecting the joint patches caused the project to fall far behind schedule.

The contractor and water agency became aware of FlexSleeve part way through construction, and qualified it for use by performing weld and hydrostatic pressure tests. Construction productivity increased 28% after FlexSleeve was introduced to the project and FlexSleeves were used for every 4th joint from that point on.

LPS’ client, OEC, received a prestigious award for “Innovation in Engineering & Infrastructure” for using FlexSleeve on this project. The INOVAINFRA award is voted on by independent jurors from engineering and construction associations and sponsored by the widely read  “O Empreiteiro” construction magazine in Brazil.
