管材尺寸(壁厚允许偏差)不符合，可能会影响安装的适配性，壁厚偏薄的管材承压能力可能偏弱，在输水等相同承压工况下更易出现破裂、渗漏问题;熔融温 度不合格的管材，其原料配方或生产工艺存在缺陷，会导致管材的热稳定性和结构均匀性变差，在高温环境下易出现软化、变形，低温环境下则会变脆、开 裂，无法适应正常的使用温度区间;氧化诱导时间偏低，说明管材的抗氧化能力不足，在加工、存储或长期使用过程中，易受氧气、紫外线等因素影响发生 老化降解，表现为表面龟裂、材质变脆、力学性能下降，不仅会缩短管材的使用寿命，还可能因管材突然破裂引发介质泄漏、炸裂等。 本次抽查发现的不合格产品将移交被检主体及产品标称的生产企业所在地市场监管部门依法进行处理。 2025年海南省流通领域塑料管材产品质量监督抽查不合格产品 中国质量新闻网讯 据海南省市场监督管理局网站消息，2025年第4季度，海南省市场监督管理局对全省流通领域塑料管材产品进行了监督抽查。本次抽查了 28批次产品，经检验，不合格2批次。 本次监督抽查依据GB/T10002.1-2023、GB/T18742.2-2017、JG/T3050-1998、GB/T5836.1-2018、GB/T ...
