焦化装置内部的低瓦放火炬管线有必要保温吗?
Reply #42017-10-14
今天突然发现我们焦化装置内部的低瓦放火炬管线保温了的,而其它装置低瓦管线是未保温的,不知道是设计就是这样,还是当初保温时弄错了。

无需保温,一般瓦斯含水很少,只是有些凝液凝点也极低,一般不会发生冻凝现象,没必要保温,我们全场低瓦管线都没有。

没有必要保温,沿途低瓦罐保证畅通就好,你们装置区内低瓦管线都保温了?

一般不保温,除非是酸性气等降温会冷凝结晶的管道,这种情况下不仅要保温还要伴热

可以问一下设计单位设计时是如何考虑的,保温的目的是什么? 一般低压放火炬管线都没有保温,催化和焦化都是不保温的。除非设计时,要什么什么要求或特殊考虑,要说清楚。

其他的同类管线没有保温,看来这个保温是多余的

保温的多余了吧?想多赚点工程量。
