Description

双层FBE外缠聚乙烯复合带结构
技术领域
本发明属于热煨弯管领域，具体涉及一种双层FBE外缠聚乙烯复合带结构。
技术背景
由于热煨弯管形状特殊，天然气管道敷设施工现场使用多集中在地形起伏相对较大、道路状况较差的区域内，运输过程中易受到磕碰撞击。因此，要求热煨弯管应格外具有良好的防腐、耐磨和抗冲击性能。
发明内容
为了解决上述问题，本发明的目的在于提供一种双层FBE外缠聚乙烯复合带结构，本发明的目的采用以下技术方案实现：
一种双层FBE外缠聚乙烯复合带结构，包括双层FBE、聚乙烯复合带，所述聚乙烯复合带缠绕在双层FBE外面。
优选地，聚乙烯复合带厚度为2.15mm。
优选地，聚乙烯复合带宽度为150mm。
优选地，聚乙烯复合带拉伸强度大于20Mpa。
优选地，聚乙烯复合带维卡软化点大于110摄氏度。
优选地，聚乙烯复合带断裂伸长率小于600％。
相比现有技术，本发明的有益效果在于：本发明的涂层结构简单，施工容易，复合带采用作业线机械缠绕，其剥离程度、抗冲击等性能都很可靠，双层FBE和聚乙烯复合带的结合提高了弯管防腐的质量和可靠性。
附图说明
图1为本发明双层FBE外缠聚乙烯复合带结构示意图。
具体实施方式
下面结合附图以及具体实施方式，对本发明做进一步描述：
如图1所示，本发明公开了一种双层FBE外缠聚乙烯复合带结构，包括双层FBE1、聚乙烯复合带2，聚乙烯复合带2缠绕在双层FBE1的外面。
聚乙烯复合带防腐采用冷带热缠聚乙烯复合带的方式，将聚乙烯专用料和胶粘剂热合而成复合带，在作业线上集中预制，采用缠绕机把复合带缠绕在沿弯曲曲率半径旋转的弯管表面。双层熔结环氧粉末(双层FBE)外缠的聚乙烯复合带由熔结环氧粉末内层、改性熔结环氧粉末外层及聚乙烯胶黏带组成。内层环氧粉末与一般的单层FBE相同，外层的环氧粉末经过改性，提高防腐层的抗机械损伤性能。聚乙烯复合带厚度为2.15mm，宽度为150mm，拉伸强度大于20Mpa，维卡软化点大于110摄氏度，断裂伸长率小于600％。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下还可以作出若干改进，这些改进也应视为本发明的保护范围。
