This publication provides guidance on the design of systems that use flexible connections for high-pressure gas. The publication includes flexible connections for the charging and discharging of compressed, liquefied and dissolved gases. Cryogenic fluids are excluded.
Doc 42 was originally published in 1986 and revisions have reflected technical and operational progress as well as the publication of new standards. This edition reflects this and in particular the publication of new ISO standards.
The publication is intended for those who specify and operate systems that have high pressure connections.
