石油提炼中管道电伴热带保温选型原则

信息来源:皖缆集团股份有限公司 浏览次数:177 发布时间:2018-08-01

       在石油化工提炼生产中,石油的提炼中需要使用大量的管道,管道主要起到了很大的运输作用,在冬季受到气温的降低,为保证正常的石油输送,需要使用保温防冻,在普通的场合没有防爆防腐要求用普通型的电伴热带就可以了,如果用于石油生产厂区有防爆防腐工业场合的话再加上环境的要求较高,这种要求下,我们需要用防爆或防腐、阻燃型电伴热带产品。

       在正常的石油生产中根据不同的要求,一般会用到自限温电伴热带、恒功率电伴热带这2种伴热产品,具体的使用上,同时我们需要考虑经济的节省和技术要求等个因素方面考虑,建议参照以下选型原则:

       1.在石油提炼中,安装熔点的不同,会提炼出各种石油分炼产品,其中在初次开采中,石油中含有各种杂质和气体,需要进行油气分离提炼,油气分离缓冲罐及天然气分离器组成的油气分离区,地面油管道等这些操作对温度的要求比较高,需要考虑高温型电伴热带如恒功率电伴热带,再配合使用一套防爆配电箱、温控器进行操控,可以很精确的进行温度控制。

       2.给水箱、给水管道一般远离防爆区,这类只是用于水管伴热的,且温度要求不高,只要使水温一直维持在设定范围内即可,选用自限温伴热带,就能够满足要求。

       3.在阀门弯头较多区域,可能呈现穿插重叠式布线,因此不适宜恒功率电伴热带,易选用自限温伴热带。

       4.恒功率电伴热带不能随便剪切,一般用于短距离的安装中,而自限温电伴热带可随意切开,能够满足各种不同场合的使用。
