翠妹兒：杰哥，給水管大概就是上幾期說的內容了，排水管呢。杰哥：排水管主要用的多的就是PVC-U這種管材。一定義：PVC-U管道:是以聚氯乙烯樹脂為主要原料，加入適量的穩(wěn)定劑、潤滑劑、填充劑、增色劑等經塑料擠出機擠出成型和注塑機注塑成型，通過冷卻、固化、定型、檢驗、包裝等工序以完成管材、管件的生產。二性能特點：1.物化性能優(yōu)良，耐化學腐蝕，抗沖強度高，流體阻力小，較同口徑鑄鐵管流量提高30%，耐老化，使用壽命長，使用年限不低于50年，是建筑給排水的理想材料。2.質輕耐用，安裝方便，有力的加快了工程進度。3.節(jié)約建筑費用，相對于相同規(guī)格的鑄鐵管，可較大降低施工費用。三PVC-U排水管的連接：連接方式主要有密封膠圈、粘接以及法蘭連接3種：；；與管道的連接也都是采用法蘭連接。四PVC-U排水管的安裝：。、割刀和割管機等工具.斷口應平整,斷面處不得有任何變形?！闫驴?坡口長度一般不小于3mm,坡口厚度宜為管壁厚度的1/3~1/2.坡口完成后,應將殘屑清理干凈。清潔劑擦洗干凈.根據膠粘劑的性能和氣候條件靜至接口固化為止。。翠妹兒：噢，杰哥。室內采用PVC-U作為排水管，性價比很高嘛。杰哥：嗯。這期就是PVC-U排水管的一些內容了。我有說得不對的地方。</p><p>

DN200PVC-U雙壁波紋管產品介紹PVC-U雙壁波紋管于二十世紀九十年代初在西方發(fā)達國家被開發(fā)成功并得到大量應用。隨著我國城市文化的迅速發(fā)展及國家對環(huán)境保護工作的進一步重視，PVC-U雙壁波紋管將有很大的應用空間。其合理的中空環(huán)形結構設計，具有質輕、強度高、韌性好的特點，同時，還具有易敷設、阻力小、成本低、耐腐蝕性強等優(yōu)點，其使用性能和經濟效益遠遠超過傳統的鐵管和水泥管，是工程材料的更新換代產品，被大范圍地應用在地下埋設的各種管道。產品特點1、環(huán)剛度大：管壁采用合理的中空環(huán)形結構設計，較大提高了管材的環(huán)剛度，在相同用料的情況下，可承受更大的環(huán)境壓力。2、流體阻力?。簝缺诠饣?，摩擦阻力明顯小于混凝土管。實踐證明，在相同的坡度下，采用直徑較小的雙壁波紋管就可以達到相同的流量，在相同的管徑下，采用雙壁波紋管可以減小坡度，有效地減少開挖的工程量。3、連接密封性好：采用彈性密封圈承插連接，連接密封性明顯優(yōu)于金屬管和混凝土管。4、耐腐蝕性優(yōu)良：具有優(yōu)異的耐酸堿鹽等介質的腐蝕，耐腐蝕性明顯優(yōu)于金屬管和混凝土管。5、施工簡易：質量輕、長度大（接頭少），對于管溝和基礎的要求低，連接方便，施工快捷，綜合造價低。北京聚氯乙烯排水管規(guī)格</p></p><br
