Abstract
A self-propelled pipe lining system adapted to create an internal liner member on a pipe or other tubular structure, the system being the combination of a sprayer apparatus, an umbilical member connected to the sprayer apparatus and supplying the lining material, electrical power and communication, a plurality of propulsion devices mounted onto the umbilical member, and an accumulator reel for retaining the umbilical member. The spraying apparatus and propulsion devices are independently powered and controlled such that each may be accelerated or decelerated as required to maintain the sprayer apparatus at a constant speed during the application process. The propulsion devices are detachable from the umbilical member.
