As an API 570 Piping Inspector, I enjoyed this video.
Could somebody address if it's SOP to actuate the relief valve manually by lifting up on the handle on the valve head. I was trained, by a very senior boiler tech., to test the relief valve this way every time I came on shift. However, the boss at my last job had a fit and stated that the valve was only tested when it was sent away for inspection. If this is true, then why does the relief valve have an actuating handle. The shift key went out on my computer, so I cannot type question marks-please excuse-John in Texas
This is the question that lead me here. Can someone provide any insights on the topic?
As recommended by the ASME, a try lever test should be performed every 30 days, or after any period of inactivity. - Low Pressure Boilers fifth edition. Fredrick M. Steingress
Hi Guys, Does the inspector witness an accumulation test of the safety valve on the boiler ? In my experience I have yet to see an inspector know what the firing rate on the boiler is. Without knowing, its not a proper test. They dont even ask.

That 1511 test was wet lol
Hey Where Heat Recovery for Steam Train locomotive!?
Most steam engines used waste steam as a feed water preheater before being sent up the stack to help induce a draft
@@Quakefire Excellent. Why draft is needed in stack? Thanks for your time.
@@cck1496 the draft helps pull hot gases through the length of the boiler to help heat the water
What does VR stands for?
Valve Repair
@@gprimeofx thanks
“Verified Repair”. only the shop Certified for VR can VR a valve, or else it will be None Coded
Our underwriter began to demand replacement of the safety valves on our 800HP JB boilers every year. Six practically new year-old safety valves thrown in the scrap bin each and every year. What a waste.
I work at a VR shop that fixes relief valves. That's hilarious.. I'll sell yall new valves and buy back the old ones as a credit lol.
