Patent ID: 7940297

Claim:
An inspection system for inspecting a pressurized gas pipeline, the inspection system comprising: an elongate flexible guide member; a first conduit having first and second ends and configured for insertion into the pipeline, the first conduit being further configured to receive the guide member therein, thereby facilitating entry of the guide member into the pipeline, the first conduit further having a cross section defining an outer width dimension; a transition member adjacent the second end of the first conduit for facilitating a change in direction of the guide member as the guide member enters the pipeline from within the first conduit, the transition member being attached to the first conduit and configured to not extend beyond the outer width dimension of the first conduit, thereby allowing the first conduit to be inserted vertically into an entry hole in the pipeline having a diameter approximately the same size as the outer width dimension of the first conduit without interference from the transition member; and a camera attached to the guide member and configured to pass through the first conduit and into the pipeline.
