ISO 7314给出了适用于在-55°C至+400°C的液体和气动系统中连续运行的中压、高温、柔性金属软管组件的规范，短时间的偏移可达+650°C。 本国际标准涵盖的软管组件拟用于航空航天应用中，用于在气动系统、排气系统、加热和通风系统以及仪表空气系统中输送空气和其他气体。ISO 7314不包括流速超过54 m/s的组件；更高的速度需要特殊的减振装置。 按照本国际标准规定的规格供应的软管组件可分为两种类型: 类型1:卷曲内管-焊接，中等质量和中等柔韧性。 类型2:卷曲内管-无缝或对接- 焊接和重绘，质量低，灵活性高。

ISO 7314 gives specifications for medium pressure, high temperature, flexible metal hose assemblies suitable for continuous operation in liquid and pneumatic systems from - 55 °C to + 400 °C, with short duration excursions up to + 650 °C. The hose assemblies covered by this International Standard are intended for use in aerospace applications for conveying air and other gases in pneumatic systems, bleed air systems, heating and ventilating systems and instrument air systems. ISO 7314 does not cover flow velocity in such assemblies exceeding 54 m/s; higher velocities require special vibration-dampening devices. Hose assemblies supplied to the specifications laid down in this International Standard may be of two types: Type 1: Convoluted inner tube - welded, of moderate mass and moderate flexibility. Type 2: Convoluted inner tube - seamless or butt-welded and redrawn, of low mass and high flexibility.
