背景技术
石油加热保温管是一种用于开采石油的管材，但是目前市场上的是有保温管为钢管，这种钢管为双层管，中间为真空管，这种管的保温效果不好，而且不耐腐蚀，使用寿命短，对石油的加热主要是采用对石油管路进行加热，但该方法成本高，有污染，且不能使石油管路中的石油均匀受热，进而加热效果不理想，甚至有的石油加热管是将电电热丝直接安装在加热管的内腔，这样虽然解决了加热问题，但是石油是有多种易燃物质组成，而电电热丝可能会引燃石油，造成事故。
另外，石油管道一般铺设在偏僻的地方，如果采用电能加热保温，会受到很大的空间限制，架设供电也会增加成本。

所述外钢质管道外侧设置有保温层。保温层采用复合硅酸盐材质。
本发明与现有技术相比，具有如下的优点和有益效果：
1、通过设置内钢质管道和外钢质管道两层管道可以有效增强输油管道的强度，防止漏油，还有利于保温，同时在管道上设置有依靠石油流动发电的发电装置以及加热装置，在有效保温的前提下，可以通过管道内的石油流动发电为加热装置提供电能，再对管道内的石油 安全加热，避免了普通管道加热受电源要求的限制；
2、加热装置采用加热管，同时在加热管周围填充加热介质水，可以有效对管道内的石油进行热传导或热交换，在不受电源限制的情况下，可以安全加热；
