Hydraulics of Corrosive Gas Pockets in Force Mains

Abstract

Hydrogen sulfide corrosion can occur in sewage force mains in places where the sewage does not continuously contact the top of the pipe. This situation can occur because air is drawn into the pipe when the hydraulic grade line is below the pipe, or a gas pocket cannot be dragged down a downward slope because of the buoyancy of the pocket. This paper presents and verifiers methods for predicting when each of these situations can occur and applies the results to an existing force main.
