Abstract

一种石油开采传输用预应力隔热油管保温装置，主要由外管、内管、接箍、隔热层、保温氩气所组成，其特征在于外管内装有衬管，两端焊有带螺纹密封接箍，中间有隔热层，并注有保温氩气。使之在石油钻井传输高温蒸汽中达到最佳效果。它可提高整体工作效率，组装方便，传输无泄漏，整体简洁美观，成本低廉，损耗系数大大提高，降低了传输费用。

Description

预应力隔热油管保温装置
所属技术领域
本实用新型涉及一种石油输送管道，特别是适用于油汽田开采用保温输送用管道密封保温装置。
背景技术
目前预应力隔热油管保温全部都是由双层抽真空来实现，加工精度高，难度大，如果密封不好，就会出现泄漏，将会造成保温性能大大下降，经济损失巨大。
发明内容
本实用新型的目的在于提供一种在预应力油管密封装置，就是在保温层内注入氩气，经过改进加工，节约了成本、组装方便快捷，每年可节省成本，彻底解决了隔热油管保温加工设计、制造的难题，该工艺安装后，解决了以前隔热油管保温不稳定的因素。
本实用新型的技术解决方案是：其主要由外管、内管、密封材料等所组成，通过向密封层注入氩气保温，来达到最佳效果。
本实用新型与现有技术相比具有：提高整体加工工作效率，组装方便，传输无失误，整体简洁美观，成本低廉，损耗系数大大提高，降低了传输费用。
附图说明：
图1为本实用新型实施例的结构示意图：
图中：1、外管，2、内管，3、接箍，4、衬管，5、隔热层，6、氩气
具体实施方式
结合附图对本实用新型作进一步详述：本实用新型主要由外管1，内管2，接箍3，衬管4，隔热层5，氩气6等所组成，隔热油管的主体管柱内、外管采用夹壁式封闭型焊接结构，加工时一端内管、衬管与外管、带有螺纹的接箍焊接，中间填放隔热层，焊接另一端接箍，结束后抽出气体，最后向夹层注入氩气保温。
