This study presents the fundamental principles and mechanical design analyses of oil and gas piping systems with the objective of investigating the basis for hydrostatic and pneumatic pressure integrity tests of the systems. Piping systems investigated are the pipes, pipe components (like pipe flanges and pipe bends) and pressure vessels. They constitute the static equipment for the transportation, transmission, production, processing and storage of hydrocarbon gases and liquids, and the associated fluid systems. They also provide means for process monitoring and control; as well as guide against environmental pollution, and ensure the safety of personnel and other equipment in the facility within which they are installed and operated. The study utilized the secondary data available in the accessed related literature and presented the formulations accordingly.
