The Mathematical Analysis and Review of Water Hammering in Check Valves in Offshore Industry

Abstract

In a piping system, water hammer occurs when pressure rapidly varies. As a result of these conditions, undesirable and damaging outcomes can occur, such as noise, excessive wear and fatigue, and collapse of the piping system and valves. This paper provides a review and mathematically analysis of the water hammering in check valves. The purpose of this paper is to review and mathematically analyze water hammering in check valves. Various approaches to selecting the best check valve or to modifying the design of the check valve are discussed in this paper. In addition, various equations and mathematical models are presented to evaluate and analyze water hammering in piping and check valves. There are also case studies of water hammering analysis of swing and dual plate check valves. These case studies provide examples of how water hammering can be calculated and analyzed for swing and dual plate check valves in the oil and gas industry.
