Abstract The authors present a method for the numerical computation of the end forces and couples in a three-dimensional pipe line. The method takes care of a pipe line with any number of straight parts connected by bends. A procedure of computation is also shown when parts of the pipe line are skewed. The ends of the line may be partially or completely constrained against rotation and translation. A construction for the analysis of stresses in the pipe bends is given. The method is illustrated by a sample computation of the end forces and couples in a steam main which is restrained against thermal expansion.

A long rising pipe line should be protected against the damage due to shock (or “water hammer”) which might ensue if the pumps suddenly failed. The most satisfactory method is to fit an air vessel on the delivery side of the pumps. The connexion between the air vessel and the pipe line should be constricted so that the oscillations of the water-level in the air vessel are damped. An approximate method is described in the paper for calculating the maximum expansion and pressure of the air, and its predictions are shown to be in satisfactory accord with experiment. The onset of water hammer, observed when damping was carried too far, was found to occur at velocities somewhat greater than theory suggests.

The transporting of liquids and gases is a basic need of civilization. Many methods have been and are used, ranging from the Egyptian water jar to the modern pipe line. The method used in today’s economy depends on the kind and amount of fluid to be transported. Martinis are delivered in 2 ounce glasses by a waiter, whereas oil is transported by 6 to 16 inch pipe lines. For purposes of discussion in this paper we will assume that the requirements are such that the fluid must be delivered to a particular location at a uniform rate. Thus, with this assumption, the most economical method of transporting would be by pipe. If the pipe and valve circuit is to be designed for most economical installation and operation, there are several things that should be known at the outset. Paper published with permission.
