Description

一种新型耐腐蚀输送管
技术领域
本发明涉及一种管道技术领域,尤其涉及一种新型耐腐蚀输送管。
背景技术
管道是用管子、管子联接件和阀门等联接成的用于输送气体、液体或带固体颗粒的流体的装置。通常,流体经鼓风机、压缩机、泵和锅炉等增压后,从管道的高压处流向低压处,也可利用流体自身的压力或重力输送。管道的用途很广泛,主要用在给水、输送、供热、供煤气、长距离输送石油和天然气、农业灌溉、水力工程和各种工业装置中。
目前为了考虑管道的使用寿命,达到数厂家对管道的质量要求非常严格,特别是在给水、输送、供热、供煤气等用途上,但是现有的管道长时间的使用很容易腐蚀,并且保温效果不佳,影响管道的正常使用,增加维修成本。
发明内容
本发明为了解决以上问题提供了一种结构简单、使用寿命长、耐腐蚀、输送速度快、生产成本低的新型耐腐蚀输送管。
本发明的技术方案是:所述的输送管包括输送管主体、内耐腐蚀层、外耐腐蚀层,所述的输送管主体为中空的圆柱体,所述的外耐腐蚀层紧密复合在输送管主体的外表面,所述的内耐腐蚀层紧密复合在输送管主体的内表面,所述的内耐腐蚀层和外耐腐蚀层均为纳米陶瓷复合层,所述的内耐腐蚀层和外耐腐蚀层的热传导率都比输送管主体低,所述的内耐腐蚀层的热传导率比外耐腐蚀层的热传导率低,所述的内耐腐蚀层和外耐腐蚀层由沥青层和聚乙烯防腐涂层,所述的聚乙烯防腐涂层复合在沥青层正反两面, 所述的输送管主体内壁光滑,所述的内耐腐蚀层通过复合胶粘连在输送管主体内壁上,所述的内耐腐蚀层表面设有螺旋引流道,加快水流通过速度。
所述的输送管主体为PVE或PPR管。
所述的输送管主体的直径为20-40mm。
所述的内耐腐蚀层和外耐腐蚀层的厚度不同。
所述的螺旋引流道由若干非连续的螺旋弯道构成。
所述的若干非连续的螺旋弯道由若干正螺旋弯道和反螺旋弯道构成,所述的正螺旋弯道和反螺旋弯道依次交替设置,所述的正螺旋弯道和反螺旋弯道之间为光滑的内耐腐蚀层。
本发明结构简单、使用寿命长、耐腐蚀、输送速度快、生产成本低。
附图说明
图1是本发明的结构示意图。
图中1是输送管主体,2是外耐腐蚀层,3是内耐腐蚀层。
