Abstract

本发明公开了一种石油管道，由从外至内的加强层和内层构成，该内层的内壁沿管道轴线为波浪形凹凸设置。本发明采用双层结构构成石油管道的管体，保温性能强，强度高，输送石油方便，耐压性好，不易发生破损，提高了安全性；并将内壁设成波浪形，使得管道内的石油流动存在波动性，增强了湍流性，降低了粘连性。

Description

石油管道
技术领域
本发明涉及石油输送装置技术领域，尤其是一种用于石油输送的石油管道。
背景技术
石油开采后必须运输到相应的加工部门，才能得到更佳地利用，其中输送石油的石油管道则是必不可少的设备。现有的石油管道为直管结构，由于石油本身粘性，很容易粘连在管壁上，造成堵塞，给输送石油带来不便。
发明内容
本发明针对现有技术的不足，提出一种石油管道，输送石油方便，不易堵塞。
为了实现上述发明目的，本发明提供以下技术方案：一种石油管道，由从外至内的加强层和内层构成，该内层的内壁沿管道轴线为波浪形凹凸设置。
进一步地，该凹凸设置的周期长度为管道外径的2～5倍。
与现有技术相比，本发明具有以下优点：采用双层结构构成石油管道的管体，保温性能强，强度高，输送石油方便，耐压性好，不易发生破损，提高了安全性；并将内壁设成波浪形，使得管道内的石油流动存在波动性，增强了湍流性，降低了粘连性。
附图说明
图1为本发明石油管道的结构示意图。
具体实施方式
下面结合附图对本发明进行详细描述，本部分的描述仅是示范性和解释性，不应对本发明的保护范围有任何的限制作用。
如图1所示的一种石油管道，由从外至内的加强层1和内层2构成，该内层2的内壁沿管道轴线为波浪形凹凸设置。
采用双层结构构成石油管道的管体，保温性能强，强度高，输送石油方便，耐压性好，不易发生破损，提高了安全性；并将内壁设成波浪形，使得管道内的石油流动存在波动性，增强了湍流性，降低了粘连性。
将波浪形的凹凸周期长度设为管道外径的2～5倍，使得流动的石油不断经过增速和减速过程，在增速的管道里正是内径最小时，此时出现文丘里管的喷射现象，减小了石油的粘连性，提高了流动性，，从而避免出现堵塞；适合各种石油输送。
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，还可以做出若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。

Claims (2)
