THE WORLD'S LONGEST SULPHUR SUBMARINE PIPELINE

The world's longest sulphur submarine pipeline is made of steel, extends 9 mi from the $25 million Caminada offshore mine of Freeport Sulphur Co. to a mainland base at Grand Isle, La., and is protected by a coating system consisting of a primer and Bitumastic high temperature enamel incorporated with a single ply of 15 lb coal tar-saturated pipeline felt. The 14 in. dia steel casing encloses a 7 in. dia urethane foam insulated line carrying the molten sulfur, inside of which a 2.5 in. dia pipe carries superheated water to keep the sulfur at a flow temperature. The same coating system was also used on two 5 in. dia water lines strapped on opposite sides of the casing.
