Double Containment Fuel Piping - UL 1369 - 123

Double containment pipe was invented for the chemical and petroleum industries and was incorporated in the design of a system over single-wall pipe to provide an additional barrier from any potential leaks in the primary pipe. The secondary containment addressed the concerns of potential hazards of possible leaks entering ground soil or waterways. Regulations changed, and it was dictated that all underground fuel piping be double containment and be in compliance with UL 971 A due to the environmental concerns. The function and use of double containment pipe has evolved and now additionally allows for secondary or interstitial monitoring as a measure of safety and environmentally sound practice. With the safety of plant/facility personnel and environmental concerns for aboveground fuel piping, UL 1369 was released to provide a benchmark for aboveground fuel piping. This presentation will address the properties and practical benefits of double containment fuel pipe as well as the new UL 1369 aboveground fuel pipe listing.
