标准范围

本文件介绍了建筑外埋地管道系统用聚乙烯（PE）管道和配件的实施规范，符合ISO 4437系列，设计用于在温度范围-20？°C到+40？°C。该文件还给出了适当的温度相关要求。业务守则涵盖其组件准备熔合或机械连接的电源和服务线路。它还对PE管道和管件的设计、储存、搬运、运输、铺设条件和熔融质量控制以及随后的接头测试、回填、管道系统测试和调试给出了说明。笔记？对于翻新操作规范，参考ISO 11299？系列和ISO 11295的分类，以及ISO 21225系列的非开挖更换的更多信息。连接方法的最低要求见:—？附件？A(对接融合)；—？附件？B(电融合)；和—？附件？C（机械连接）。在一些国家，允许使用加热工具插座和鞍座熔合；附件中给出了加热工具熔接技术的信息？D.在地面移动或震动（如地震等）的情况下，可能有必要按照权威机构提供的指南（如欧洲规范8，[7]EN？12007-1:20 12，附录A，[8]等）实施本文件中提到的预防措施，工人的健康和安全问题超出了本文件的范围。

This document presents a code of practice dealing with polyethylene (PE) pipes and fittings for buried pipeline systems outside buildings, conforming to the ISO 4437 series, and designed to transport gaseous fuels [as defined in ISO 4437-1, e.g. methane, liquified petroleum gas (LPG), manufactured gas and hydrogen] within the temperature range –20 °C to +40 °C. This document also gives appropriate temperature-related requirements.The code of practice covers mains and service lines whose components are prepared for fusion or mechanical jointing. It also gives instructions for the design, storage, handling, transportation, laying conditions and fusion quality control of PE pipes and fittings as well as subsequent joint testing, backfilling, pipe system testing and commissioning.NOTE      For the renovation code of practice, reference is made to the ISO 11299 series and to ISO 11295 for classification and to the ISO 21225 series for further information for trenchless replacement.The minimal requirements for the jointing methods are given in:—    Annex A (butt fusion);—    Annex B (electrofusion); and—    Annex C (mechanical jointing).In some countries the use of heated-tools socket and saddle fusion is permitted; information on heated-tools fusion jointing techniques is given in Annex D.In the case of ground movement or shaking (e.g. earthquakes, etc.) it can be necessary to implement precautions mentioned in this document following guidelines provided by authorities (e.g. Eurocode 8,^[7] EN 12007-1:2012, Annex A,^[8] etc.),Workers' health and safety issues are outside the scope of this document.
