标准范围

ISO 9349:2004规定了适用于预绝缘球墨铸铁管、配件、附件及其接头的要求和试验方法，用于建造管道（或其部件），以输送水（如饮用水）、废水和其他液体，在有压力或无压力的情况下运行，安装在地下或地上，限制输送流体的温度变化。ISO 9349:2004除了提供了现有ISO标准中有关输送球墨铸铁管和配件的规范外，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 9349:2004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，其制造带有套筒、法兰或插口端，用于通过各种类型的垫圈进行连接，这些垫圈不在本国际标准的范围内；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。

ISO 9349:2004 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.ISO 9349:2004 gives, in addition to the specifications of the existing ISO 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 9349:2004 covers preinsulated ductile iron pipes, fittings and accessories of a size range extending from DN 60 to DN 600 inclusive, which are manufactured with socketed, flanged or spigot ends for jointing by means of various types of gaskets which are not within the scope of this International Standard; 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.
