ISO 28017:2018规定了标称尺寸在100到1200之间的两种类型、七个等级和三个等级的钢丝或织物增强疏浚软管的要求。在每个等级中，所有等级和尺寸都有相同的最大工作压力。此类软管适用于在环境温度为-10°C至+40°C的情况下，输送或吸入比重在1.0至2.3之间的海水或淡水，其中混合有淤泥、沙子、珊瑚和小石头。 ISO 28017:2018涵盖了两种类型的软管，如下所示: -类型1:浮动式，仅用于交付，包括提供软管浮力的浮动材料； -类型2:用于输送和吸入的潜艇型。 ISO 28017:2018未规定有关软管或软管组件使用寿命的要求。 客户有责任与软管制造商协商，规定此类要求。

ISO 28017:2018 specifies requirements for two types, seven classes and three grades of wire- or textile-reinforced dredging hoses with nominal sizes ranging from 100 to 1 200. Within each class, all grades and sizes have the same maximum working pressure. Such hoses are suitable for the delivery or suction of seawater or freshwater mixed with silt, sand, coral and small stones with a specific gravity in the range from 1,0 to 2,3 at ambient temperatures ranging from？10 °C to +40 °C. ISO 28017:2018 covers two types of hose, as follows: - type 1: floating type, for delivery only, which includes flotation material to give the hose buoyancy; - type 2: submarine type for delivery and suction. ISO 28017:2018 does not specify requirements concerning the service life of hoses or hose assemblies. Specifying such requirements is the responsibility of the customer, in consultation with the hose manufacturer.
