1.1本规程涵盖了制造和安装刚性管道吊架的可接受方法，用于支持温度为650℃的船上管道系统 ° F（343 ° C） 或更少。 1.2本规程为吊架盖、吊带和支架的设计、吊架和吊架衬里材料的选择、吊架螺栓连接和吊架间距提供了指导。 1.3可以使用其他吊架设计，前提是它们能够充分支撑无振动的管道系统，并且与预期的系统服务和温度限制兼容。 1.4以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 This practice covers acceptable methods of fabricating and installing rigid pipe hangers used to support shipboard piping systems with temperatures of 650 ° F (343 ° C) or less. 1.2 This practice provides guidance for the design of hanger caps, straps and standoffs, selection of hanger and hanger liner materials, hanger bolting, and hanger spacing. 1.3 Other hanger designs may be used provided they result in an adequately supported vibration-free piping system and are compatible with the intended system service and temperature limitations. 1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
