Planning Guide - New Technologies in Pipe Joint Fabrication (The National Shipbuilding Research Program).

摘要

In the past few years. methods of joining pipe together have been introduced to supplement and. in some cases replace, both the traditional welded and the brazed pipe fitting. It is necessary to examine what is available. and to justify its place and application in the marine market. This paper intends to examine the Swage Marine Fitting (SMF) and the Heat Recoverable Coupling (HRC) and, briefly. the Compression and the bite type fit- tings. we will look at them from economic, performance, and environment all standpoints. In the case of the SMF and HRC fittings, technical papers on the usage of each fitting and its constraints have been presented. The purpose of this paper is to evaluate them together and incorporate them into an overall piping system. In addition. the two primary guides for piping on military ships will be examined. These will be used to place the SMF and HRC into correct perspective, and to make recommendations for further applications. Comments will also be offered on the testing method and the results gained. Graphs are provided to illustrate the economic advantage of the SMF application.
