Issues regarding the drainage at the inlet of the control valve
Thread Content
I’m a beginner. Not long ago, I worked on an acrylic pressure pipeline project (only drawing work was done, no actual construction). The drawings were signed off and handed over to the client, but today I realized that the drain pipes for two control valve assemblies were placed in the wrong locations – one was accidentally placed behind the valve, and the other in front of the inlet shut-off valve. What carelessness on my part. Although it’s a supplementary image, I’m still worried that something might go wrong if it isn’t cleaned thoroughly during future maintenance. I would like to ask the experienced colleagues: if the position of such a drain valve is incorrect, could it pose serious safety hazards? (The medium is gaseous propylene, with a maximum temperature of 50 and an operating pressure of 0.3 MPa)
Generally, we don’t construct according to the design drawings, because that would lead to mistakes
