The Economics of Computer Modeled Central Ammonia Systems vs. the Use of Impact Tested Pipe and Fittings

摘要

This paper documents the requirements of the 2006 ASME B31.5 Code for Pressure Piping, "Refrigeration Piping and Heat Transfer Components," related to piping and fittings. The selection by the owner of: 1) the currently followed industry practices, or 2) the alternative design guidelines set forth in the ASME B31.5 piping code, will have a financial impact on the cost of each project In this paper we examine these alternatives, review impact testing implications, examine several money saving concepts that can be implemented in the design and construction of refrigeration piping systems and, finally, review the procedures required to comply with the B31.5 piping code requirements.
