低压玻璃纤维管线管件规范（第七版

[中文适用范围]： 范围 本规范涵盖纤维缠绕 (FW) 和离心铸造 (CC) 玻璃纤维管线管以及直径不超过 24 英寸且循环工作压力不超过 1000 psig 的管道配件。此外，根据制造商的选择，管道的额定静态工作压力也可高达 1000 psig。建议按循环压力等级购买管道及管件。标准压力额定值范围为 150 psig 至 300 psig，增量为 50 psig，300 psig 至 1000 psig，增量为 100 psig，基于循环压力（参考 5.5.1）或静态压力（参考 5.5.2） 。包括质量控制测试、静压磨机测试、尺寸、重量、材料特性、物理特性和最低性能要求。 [外文原描述]： Covers filament wound (FW) and centrifugally cast (CC) fiberglass line pipe and fittings for pipe in diameters up to and including 24 in. in diameter and up to and including 1000 psig cyclic operating pressures. In addition, at the manufacturer’s option, the pipe may also be rated for static operating pressures up to 1000 psig. It is recommended that the pipe and fittings be purchased by cyclic pressure rating. The standard pressure ratings range from 150 psig to 300 psig in 50 psig increments, and from 300 psig to 1000 psig in 100 psig increments, based on either cyclic pressure or static pressure.
