plastics pipe/tube pipe fittings quality how to? cationic 市2019 year 抽检结果 new 鲜出炉
随 plastics technology 进步 步伐不断 add fast, new technology, new material, new process 不断涌现, plastics pipe/tube versus for 传统材 material advantages 愈发突出. currently, plastics pipe/tube as is chemical building materials important formed separation, its 卫生, environmental protection, low consumption and other features is large use 户 广泛接受, main/primary type type has UPVC排 water tube/pipe, UPVC to water tube/pipe, aluminum composite/compounding tube/pipe, polyethylene (PE) (PE) to water pipe/tube and other.
2019 year, cationic market tube/pipe 理局组织 for full plastics pipe/tube pipe fittings production enterprise product quality 进行 监督抽查. 抽查涉 and cationic 市11家 enterprise production pipe/tube product 21 batch.
day front, for 抽检结果进行 announcement: 11家 enterprise 21 batch product 均检验 combined 格, issues product rate is 0%, issues enterprise rate is 0%.
此次抽查 based on GB/T 13663.2-2018《 to water use polyethylene (PE) (PE) pipeline system 第2部 separation: pipe/tube 》, GB/T 18742.2-2017《 cold hot water use polypropylene (PP) pipeline system 第2部 separation: pipe/tube 》, GB/T 5836.2-2018《 construction water use hard polyvinyl chloride (PVC) (PVC-U) pipe fittings 》, GB/T 5836.1-2018《 construction water use hard polyvinyl chloride (PVC) (PVC-U) pipe/tube 》, Q/SN001-2012《 construction water use hard polyvinyl chloride (PVC) (PVC-U) pipe/tube 》, CJ/T 225-2011《埋 排 water use belt/tape reinforcement polyethylene (PE) (PE)螺旋波纹 tube/pipe 》, GB/T 19472.1-2004《埋 use polyethylene (PE) structure pipeline system 第1部 separation polyethylene (PE) di 壁波纹 pipe/tube 》, YD/T 841.5-2016《 lower pipeline use plastics tube/pipe 第5部 separation: tube/pipe 》, JG 3050-1998《 construction use insulation electrical sleeve/set tube/pipe and parts 》 standards requirements, for plastics pipe/tube pipe fittings product specifications dimensions, toward shrink rate, fracture elongation, oxidation time, liquid pressure experiment/testing, property can, 简支梁 impact, density, Vicat softening temperature, tensile 屈服应 force, impact experiment/testing, experiment/testing, experiment/testing, ring rigid degree, ring flexible, resistant pressure property can, bending property can, resistant thermal properties, flame retardant property can, electrical properties, pipe/tube rigid degree, rate and other project 进行 检验.
