Abstract

Straight cross-country pipelines are supported throughout the length of pipeline on different forms of supports at more or less regular spans. Maximizing the distance between supports will minimize the number of supports required, which in turn reduce the total cost of erecting these pipe supports. ASME has suggested the standards for support span, but the bending stress considered in its calculation is very low (15.9 Mpa). There are other references also who have listed the maximum support span. In this paper equations for calculating the maximum span using maximum bending stress are given. Safety of the design is checked using maximum deflection. A sample problem is considered for evaluation and the results thus obtained are compared with standards like ASME B31.1, U S Army Engineer’s Manual and other references. The problem is also modeled in ANSYS and analyzed for deflection. A method of optimizing the distance between supports using ANSYS© optimization technique is also discussed.
