Scope

(a) This Standard covers manually operated thermoplastic valves in nominal valve sizes 1∕2 through 12. These valves are intended for use below ground in thermoplastic fuel gas distribution mains and service lines. The maximum operating pressure (MOP) at which such distribution piping systems may be operated is in accordance with Transportation of Natural and Other Gas by Pipeline; Minimum Safety Standards [49 C.F.R., §192 (2017)] for temperature ranges of −20°F to 140°F (−29°C to 60°C). (b) This Standard sets qualification requirements for each basic valve design as a necessary condition for demonstrating conformance to this Standard. (c) This Standard sets requirements for newly manufactured valves for use in below-ground piping systems for fuel gas [includes synthetic natural gas (SNG)] and liquefied petroleum (LP) gases (distributed as a vapor, with or without the admixture of air) or mixtures thereof. （a） 本标准涵盖标称阀门尺寸为1∕2至12的手动热塑性阀门。这些阀门旨在用于热塑性燃气分配干管和服务管线的地下。此类分配管道系统可操作的最大工作压力 （MOP） 符合管道输送天然气和其他气体;最低安全标准 [49 C.F.R.， §192 （2017）] 适用于 −20°F 至 140°F（−29°C 至 60°C）温度范围。 （b）本标准规定了每种基本阀门设计的资格要求，作为证明符合本标准的必要条件。 （c）本标准规定了用于燃气[包括合成天然气（SNG）]和液化石油（LP）气体（以蒸汽形式分布，有或没有空气混合物）或其混合物的地下管道系统中使用的新制造的阀门的要求。
