Regarding the insulation setup for the vent valves on the tower
Thread Content
I have a question: since the tower is insulated, does the vent valve at the top of the tower also need to be insulated? The towers are dry gas desulfurization towers and liquefied gas desulfurization towers. Thank you for the reply~
Is it necessary to insulate the safety valve? Since safety valves are usually installed in locations where no fluid flows, especially at the very top, where no liquid vaporizes, insulation is not required. If there is liquid in certain sections of this conduit where it exchanges heat with the atmosphere and vaporizes, insulation is required, for reference.
I’ve never seen insulation on the vent valve pipelines at the top of towers or tanks
Under normal conditions, the pump body of this safety valve needs to be insulated
Thank you for the answer. Here it refers to a vent valve, not a safety valve.
Our vent valve also lacks insulation
It provides little insulation; what is the purpose of insulation anyway?
Is the vent valve at the top of the tower connected directly to the atmosphere? Heat retention is not necessary. The pipelines leading to the flare after the safety valve can be either insulated or not. The advantage of not insulating them is that internal leaks in the safety valve can be detected: lol
It generally does not provide insulation; if insulation is needed, it is only required before the valve (including the valve itself), and not after it.
