标准摘要
[中文适用范围]: 本文件规定了两种用于输送液化石油气和液化天然气的热塑性多层(非硫化)输送软管和软管组件的要求。 每种类型又分为两类,一类用于陆上任务,另一类用于海上任务。 — A 级软管适用于陆上。 — B 级软管用于海上。 根据类别,本文件适用于 25 mm 至 250 mm 的软管尺寸、10.5 bar 至 25 bar 的工作压力以及 −196 °C 至 +45 °C 的工作温度。 注 EN 1474-2 中还规定了海上液化天然气 (LNG) 软管组件。 EN 1474-2 不仅规定了海上使用,还规定了船到岸和其他液化天然气传输应用。 [外文原描述]: This document specifies requirements for two types of thermoplastic multi-layer (non-vulcanized) transfer hoses and hose assemblies for carrying liquefied petroleum gas and liquefied natural gas. Each type is subdivided into two classes, one for onshore duties, and the other for offshore. — Class A hose is for use onshore. — Class B hose is for use offshore. This document is applicable for hose sizes from 25 mm to 250 mm, working pressures from 10,5 bar to 25 bar and operating temperatures from −196 °C to +45 °C, according to class. NOTE Offshore liquefied natural gas (LNG) hose assemblies are also specified in EN 1474-2. EN 1474-2 does not only specify offshore use, but also ship to shore and other LNG transfer applications.
