Scope

This Code covers the design, fabrication, installation, inspection, and testing of pipeline facilities used for the transportation of gas. This Code also covers safety aspects of the operation and maintenance of those facilities. (See Mandatory Appendix Q for scope diagrams.) This Code is concerned only with certain safety aspects of liquefied petroleum gases when they are vaporized and used as gaseous fuels. All of the requirements of NFPA 58 and NFPA 59 and of this Code concerning design, construction, and operation and maintenance of piping facilities shall apply to piping systems handling butane, propane, or mixtures of these gases. 本规范涵盖用于天然气运输的管道设施的设计、制造、安装、检查和测试。本守则还涵盖这些设施的运营和维护的安全方面。（有关范围图，请参阅强制性附录 Q。 本规则仅涉及液化石油气汽化并用作气体燃料时的某些安全方面。NFPA 58 和 NFPA 59 以及本规范中有关管道设施的设计、建造、操作和维护的所有要求均适用于处理丁烷、丙烷或这些气体混合物的管道系统。
