标准范围

本文件规定了用于在压力下输送流体的热塑性管道系统中的热塑性法兰适配器和相应的松散背衬法兰的配合尺寸。它适用于公称外径（dn）为16 mm至2 500 mm、公称压力高达25 bar[1]（PN 25）的管道的法兰适配器和松背法兰。本文件规定了用于以下用途的法兰适配器的尺寸:-对接熔合管道系统；-承插熔融管道系统；-胶接管道系统。注1对于本文件未涉及的尺寸（如dn450或dn630）的特定连接，或特定设备（蝶阀），市场上有特定的解决方案。本文件适用于由金属、热塑性塑料或金属和热塑性塑料组合制成的松散背衬法兰。本文件还提供了有关垫圈的信息，并给出了正确组装实践的一般建议。注2工业应用不包括在本文档中。ISO 15493[1]、ISO 15494或ISO 10931[2]涵盖了工业应用的产品。[1]1 bar=0.1 MPa=105 N/m2。

This document specifies the mating dimensions for thermoplastic flange adapters and corresponding loose backing flanges intended to be used in thermoplastic piping systems for the conveyance of fluids under pressure.It applies to flange adapters and loose backing flanges for use with pipes with nominal outside diameters (d_n) from 16 mm to 2 500 mm and nominal pressures up to 25 bar[1] (PN 25).This document specifies the dimensions of the flange adapters intended to be used for:— butt fusion piping systems;— socket fusion piping systems;— adhesive jointed piping systems.NOTE 1 For specific connections with dimensions (e.g. d_n450 or d_n630) not covered in this document, or specific equipment (butterfly valves), specific solutions are available on the market.This document is applicable to loose backing flanges made from metal, thermoplastics, or a combination of metal and thermoplastics.This document also provides information on gaskets and gives general recommendations on correct assembling practices.NOTE 2 Industrial applications are not covered by this document. Products intended for industrial application are covered by ISO 15493^[1], ISO 15494 or ISO 10931^[2].[1] 1 bar = 0,1 MPa = 10⁵ N/m².
