841-XX-002-A would be the tag for the thermal oil exhaust gas heater. Here is a more detailed pic. The more i look at it, the more it looks like an air release trap. Thoughts?
Guys kindly help me with this symbol (the one w/ red markings). I want to be sure if i'm correct on this one. Other drawings in our company uses other standards and its f*cked up.
I'm currently updating a P&ID and a person from the rig added an equipment. He says it's a pressure absorber but I can't find any pressure absorber in the P&ID symbology. I'll attach some of the pics he gave me and hopefully some of you can help me with this.
