Fabric reinforced petrolatum coated tapes represent one of the oldest established protective coatings for buried pipe and other metallic structures which are in use all over the world at the present time. They originated from the widespread concern that arose during 1925/1926 over cases of severe corrosion of gas mains caused by stray electric currents from street car lines. At that time there were a number of resulting fatal gas explosions. Existing asphaltic protective systems were not regarded as adequate and the idea was conceived of applying a permanently plastic waterproof bandage to the metal surface. Since that time tapes consisting of a petrolatum coating on a textile reinforcement have become widely used by public utilities and others in the British Isles, Europe and other parts of the world. A pipe coating survey conducted in 1959 by the Canadian Gas Association showed more companies reporting the use of this type of wrapping than any other material for underground field applications such as the protection of joints, couplings and valves.
