The Basics of Pipe Thermal Expansion. Materials expand when heated and contract when cooled. Pipes are not immune to these laws of nature, so they will also expand and contract with varying temperature. This article will introduce the basics of stresses and anchor loads induced by thermal expansion. Visa mer We will start with some definitions of commonly used flexibility terms. Stress is defined as force per unit area in a material: S = F/A (Equation 1) S = Stress (psi-can be negative or positive) F = Force (lbf-can be negative or positive) A … Visa mer Now that we have an idea of the magnitude of the stresses and anchor loads in a pipe system, there are several ways to help the situation. The simplest method is to take … Visa mer The geometry of the pipe system will usually determine the anchor loads; however, not every piping arrangement will permit the pipe to naturally flex. A confined space or … Visa mer Pipes bend, even under their own weight. The longer the pipe, the easier it is to bend.

The piping system must have enough flexibility to handle the expansion. Two horizontal pipe loops between fixed anchors. These pipes are subject to high temperature expansion. Deflection of the piping system caused by thermal expansion.

WebbExpansion loops are one of the most effective ways to increase the flexibility in the piping system. The stress is generated in the pipelines due to thermal expansion or contraction and it can be damped by the arms of the loops mounted vertically to the mainline. Section 319.7 of ASME B31.3 tells that the expansion loops or expansion joints are ...
