PE缠绕结构壁管B型-克拉管

所属分类：

排水排污管系列

产品特点

统塑牌高密度聚乙烯缠绕增强管B型（克拉管）是一种内壁光滑，外壁为螺旋形状加强肋，经螺旋缠绕工艺制成的结构壁管材，属柔性管材。管材采用高密度聚乙烯（HDPE）树脂为主要原材料，在热熔状态下通过热态缠绕成型工艺，并以聚丙烯（PP）单壁波纹管为支撑结构支撑，并在热态未脱模前，通过滚动风方式冷却，管道逐步散热，壁厚均匀的具有高抗外压能力的特殊结构壁管材。

产品详情

管材采用承插式电熔连接和橡胶圈柔性连接。承插式电熔连接的管道两槎在生产时被加工成承口和插口，并在承口端嵌入电熔丝，在管道连接时，只需接入电源即可完成焊接，并且可以使管系统实现零渗漏。该产品被广泛应用城市排水、市政排水、电力、石化、煤矿、通风等领域，是钢筋混凝土、铸铁管的理想换代产品。该产品2018年被广东省高新技术企业协会认定为“广东省高新技术产品”。

性能特点

热态缠绕成型熔缝质量高

从挤塑机口模挤出的处于熔融状态的平料带和O型料带包裹的PP单壁管，按预定的位置均匀的缠绕在加热的滚筒模具上，保证了结构壁管熔接缝质量。特别是结构设计中平料带的熔接缝被聚乙烯包覆支撑管所覆盖，提高了制品整体的抗外压能力

安装性能优异

管道连接采用在承口预埋电熔丝同材质承插电熔连接技术，连接质量高。可做到100%无泄露，保证了管道系统寿命的相同性和运行的安全性。同时，由于该产品在同等应用条件下比其它管材重量轻，便于运输，施工方便快捷，可降低施工费用，在应用范围，不需混凝土垫层和混凝土管基沟槽合格后即可直接敷管，基本上做到边开挖、边下管、边回填，简化了施工程序，缩短了工期

较好的柔韧性

管材在宏观上具有很好的柔韧性，而局部管段又有很强的刚性和整体抗外压能力，在有超重荷载路面下使用时，可保证通行安全。由于管材的柔韧性，发生地震、在面不均匀沉降等地质活动时，也能将管道破坏损失降为最小，从而提高了公用设施抗震减灾的能力

HDPE可循环回收使用

属绿色环保型产品，管的主要原材料高密度聚乙烯，无任何毒性，在生产过程中也无任何染物产生，废管道可100%回收再利用。确属环保安全型绿色产品

抗腐蚀、耐老化、使用寿命确保50年

高密度聚乙烯具有极强的耐化学药品腐蚀和侵蚀的能力。因此管在输送腐蚀性流体或在腐蚀性地土壤中敷设时，不须防腐处理，性能大大优于其它管材。该产品在设计过程中，选择合理的产品结构形式，确保塑管的使用寿命在50年以上，并在寿命期内免维护

管内壁糙率低，输水量大

产品内壁糙率N约为0.010，因此输送流体时比摩阻小，相对同内径其它管道，在同等使用条件下输水量较水泥管可大幅度提高。特别是在施工场地狭窄、建筑密集、地下管线复杂和交通繁忙路段以及在酸碱性土壤铺设时，更具优越性
