API PUBL 4716, 2002 Edition, April 2002 - Buried Pressurized Piping Systems Leak Detection Guide

INTRODUCTION

Background

Because of the complex physical configuration and unique operational characteristics of buried pressurized piping systems found in petroleum product terminals and airport hydrant fueling systems, proven leak detection technologies have not previously been available. However, within the last few years, several technology vendors and companies have worked to develop and improve leak detection technologies for these unique piping systems. The purpose of this Study was to assess the success of their efforts to date.

In 1997, the American Petroleum Institute (API) and the Air Transport Association of America (ATA) formed a joint Leak Detection Committee to review the new generation of leak detection technologies for potential application to petroleum product terminal piping as well as the hydrant fueling systems at airports. The Leak Detection Committee defined its goals as follows: "Identify and evaluate reliable leak detection technologies that are currently commercially available and cost-effective for buried piping associated with airport hydrant fueling systems and petroleum product terminals."
