As projects get more complex and space is a limitation, piping engineers face a chal- lenging task to fulfill all requirements of safety and functionality of piping under given constraints. In this project, there were eight tanks with eight pumps in an area of 24.5 m x 50.5 m. Each tank size was 8.5m, which left limited space to plan pumps and piping connected between pumps and tanks. All these tanks were enclosed in a dyke wall to satisfy safety norms of industry to avoid spillage in case of leakage of tanks. Lines running from tank to pump have to cross dyke walls. To meet the requirement of a spill proof dyke wall and provision of sufficient flexibility to piping, we used the concept of Dyke Bellows.
