Abstract
Since the early 1960's heatshrinkable sleeves have been used for the corrosion protection of girthwelds on buried, factory coated steel pipelines. With the increasing use of high performance, line coatings such as fusion bonded epoxy and three layer polyethylene, the need arises for an equivalent performance, field applied, girthweld coating. This paper details the development, testing and field application of a new three layer, hotmelt-epoxy shrinksleeve system.
A brief description of the new sleeve’s simple installation procedure is given together with details of a long term hot water immersion test. Several project installations are reviewed including both new construction and refurbishment of existing deteriorated coatings.
