Abstract
Abstract A pipeline system is provided for a pumping system for fluid products, such as gasoline, diesel fuel and chemicals, and including a pump for pumping such products from a storage tank through through the primary pipeline of the pipeline system to a product dispenser. The pipeline system includes a secondary containment system for the primary pipeline between the tank and dispenser which includes telescoping pipe sections of different diameters. The telescoping piping is installed around the primary pipeline and the pipe sections are, prior to final installation, movable between intermediate and final positions, for enabling completion, testing and inspection of the primary pipeline prior to final completion of the secondary containment system. One section of the telescoping piping is a flexible corrugated pipe which is able to bend around elbows. Compression seals and ring clamps are used to connect the components together.
