标准范围

ISO 9349:2017规定了适用于管道（或其零件）施工用预绝缘球墨铸铁管、配件、附件及其接头的要求和试验方法:-输送水（如饮用水）、废水和其他液体；-有压力或无压力操作；-安装在地下或地上；-限制输送流体的温度变化。这些管道主要用于通过提供外部绝缘防止输送的水结冰。注1:在本文件中，所有压力均为相对压力，单位为巴[1]）。ISO 9349:2017除了提供了现有的球墨铸铁管和配件国际标准的规范外，还提供了预绝缘球墨铸铁管、配件和附件的保温层和外壳的材料、尺寸和公差、机械和热性能规范。ISO 9349:2017涵盖了尺寸范围从DN 60到DN 600（含）的预绝缘球墨铸铁管、配件和附件，如下所示:-采用不在本文件范围内的各种类型的垫片进行连接的承插端、法兰端或插口端制造；-在工程中预绝缘（不包括现场应用绝缘层和/或套管）；-通常提供内部和外部涂层；-适用于0°C至50°C的流体温度，不包括霜冻。注2:制造商和买方之间的协议允许其他应用。[1] 100千帕=1巴。

ISO 9349:2017 specifies the requirements and test methods applicable to preinsulated ductile iron pipes, fittings, accessories and their joints for the construction of pipelines (or parts thereof):- to convey water (e.g. potable water), wastewater and other liquids;- to be operated with or without pressure;- to be installed below or above ground;- to limit temperature variations of the conveyed fluids. These pipelines are mainly used to prevent the water to be conveyed from freezing by providing external insulation.NOTE 1 In this document, all pressures are relative pressures expressed in bars[1]).ISO 9349:2017 gives, in addition to the specifications of the existing International Standards for the conveying ductile iron pipes and fittings, specifications for materials, dimensions and tolerances, mechanical and thermal properties of the thermal insulation layer and external casing of preinsulated ductile iron pipes, fittings and accessories.ISO 9349:2017 covers preinsulated ductile iron pipes, fittings and accessories of a size range extending from DN 60 to DN 600 inclusive, which are as follows:- manufactured with socketed, flanged or spigot ends for jointing by means of various types of gaskets which are not within the scope of this document;- preinsulated in the works (excluding on site application of the insulation layer and/or the casing);- normally delivered internally and externally coated;- intended for fluid temperatures from 0 °C to 50 °C, excluding frost.NOTE 2 Other applications are possible by agreement between manufacturer and purchaser.[1]) 100 kPa = 1 bar.
