Currently there are thousands of miles of underground pipes and associated infrastructure, much of it in the chemical and nuclear sectors.
When pipes are originally laid they are, by definition, theoretically perfect. Such pipes are usually made of some kind of DISSIPATIVE earthenware material, which means if flammable liquids such as solvents, for instance, pass down them, any build-up of static is dissipated through the pipe, thus preventing the threat of explosion.
When a pipe is in need of repair, be it a hole, a crack or a displaced joint, other substances are, by definition, introduced into the pipe to facilitate that repair.
Up to now such materials have always been fibre glass patches, polyester liners and epoxy coating systems, which are insulators, meaning they break the continuity of the static flow and allow it to build-up, causing the potential for spark, explosion and possible chain reaction.
Such products do NOT CONFORM WITH the BS60079-32 standard for electro-static hazards in potentially explosive atmospheres.
Effectively current repair methods introduce the potential for explosion and spark, because they are NOT dissipative! The environmental risk may be negated, however, by definition, an explosion risk is introduced.
CONDUCTORLINER is the first product in the world that conforms with HSE legislation and that is EN/BS60079-32 compliant.
