COATING AND THERMAL INSULATION OF SUBSEA OR BURIED PIPELINES

Subsea or buried pipelines are routinely protected by anticorrosion coatings in conjunction with cathodic protection. The coating provides the primary defense barrier, isolating the steel pipeline from its corrosive environment, while cathodic protection provides a backup if the coating is breached. In addition to corrosion protection, many pipelines require thermal insulation to prevent the crude oil or natural gas from producing waxes or hydrates. This article presents information about both anticorrosion coating systems and thermal insulation for oil and gas pipelines. Various types of pipeline coating systems are presented along with some of their key characteristics. These include asphalt and coal tar, tape wrap, two-layer extruded polyethylene, fusion-bonded epoxy, three-layer polyolefin, and multicomponent composite coatings. For insulation systems, particular emphasis is given to selection criteria, and three types of insulation systems available today are described: low, medium, and high insulation systems.
