摘要

A fundamental concern of members of the shipbuilding community is the escalating cost of repairing and fabricating piping systems. These shipbuilders are searching for ways to reduce installation costs and to improve the quality and timeliness of shipyard output. The primary cost in attaching segments of a piping system is directly related to installation man-hours for welding or brazing, flushing, hydro-static testing, quality assurance and potential rework. The more labor intensive the piping installation, the greater the need for an alternative method. New technologies have provided more cost effective methods for permanently joining piping. One viable alternative is the Swage Marine Fitting. Swage Marine Fittings (SMF) are mechanically applied connections that significantly reduce installation man-hours by eliminating hot- work and conventional N.D.T. This paper will discuss the history of welding and brazing, the development of mechanically applied pipe connections and the potential impact that this technology will have on the future of piping fabrication and repair.
