The material withdamaged markshouldbeforbidden.Ifitisdiscoveredthat there is problem in the pipeline quality, recheck itbefore using.管材的端面应垂直于管材的轴线。管件应完整、无缺损、无变形。End face of pipe should be upright to the axes of pipe.Thepipefittingsshouldbeintact,withoutlackanddistortion.管件和管材不应长期置于阳光下照射，为避免管子在储运时弯曲，堆放应平整。搬运管材和管件时，应小心轻放，避免油污，严禁剧烈撞击，与尖锐物触碰和抛、摔、拖。管材开口处应及时封堵，以免管道堵塞造成不必要的浪费。Pipefittingandpipeshouldnotbeplacedinthesunshineforalongtimetoavoidthepipecurvein42020 年 4 月 19 日文档仅供参考storage and transportation, and piling up them should be level. When conveying pipe and pipe fittings, they should handled with care and avoid oil stain. Strong bump, cast,throw and draw is forbidden. Pipe hatch should be immediately plugged to avoid pipe jam and unnecessary waste.施工现场与材料存放处温差较大时，应于安装前将管件和管材在现场放置一定时间，使其温度接近施工现场环境温度。When there is large difference in construction field and storage temperature, should place pipe fitting at the field before installation for certain make its temperature closure to environmentand pipetimeandtemperatureof construction field.本项目PPR 管道采用热熔连接，施工前应仔细检查所使用的热熔机具、割刀是否符合要求和正常使用，使用的电源及电线是否正常和安全。如下图：This project pipe-PPR pipe adopts heat fusion. Before construction, should carefully examine whether the usinghot melt equipment and cutter knife accord with requirements and normal service, the using power supplyand wire are normal and security. as the following drawings.52020 年 4 月 19 日文档仅供参考材料进货检验：Material-stocking test为确保安装质量，材料进货时应严格检验，其管径椭圆率应10%，管材同一截面的壁厚偏差应14%，内外壁应光滑、平整，无气泡、裂口、裂纹、凹陷、脱皮和严重的冷斑及明显的痕迹。Forinsuringtheinstallationquality,shouldstrictlytest the material when it is stocked.
