7 Tips for Hydrostatic Pressure Testing


So from the references that I am using for hydrostatic pressure testing, the test itself can be used up to 15,000 PSIG (AKA 1034 barg for conversions via pressure). This is up to ASME standards.

Letś get to Business.

First, make sure everyone involved can mutually agree. The absolute most simple tip I can recommend. Once that has been accomplished, the test takes roughly five minutes for completion. This is with no leakage at all and no deformation that will permanently stay. Good products will result in no deformation. Once this has been accomplished you can proceed to the next step in the pressure test. They will all vary depending on the process in which you are using.

Tip number two. Just as a car pick the proper fluids. I wouldn´t suggest using your standard 10W 30 motor oil if you were testing the pressure for compressed air in an AC unit. Not only would you lead to some contamination period as itś a completely different area of fluid in two different areas, but certain things that get contaminated can not be decontaminated completely. You will end up having to start completely over or with a really pissed off boss. So make sure you check your fluids. Does it meet the manufacturer’s standard or recommendation? Is it up to ASME specs? Most important, is it the correct one? Measure twice, cut once. It goes in any area.

Tip number three. Make sure your gauge of choice is working properly. If you are more old school and you know its broken, for instance, letś say you have been checking pressures on various items or fluids for years. You have that one gauge you just go to as your main choice, it always reads twenty or thirty and you have known for as long as you can recall. Make sure you subtract that twenty or thirty to you from the total reading or your reading is going to come off way off the chart standards. This will save you time and prevent overboard measures.

Tip number four. Be sure to have the proper hoses and fittings. Do not get’s something because the guy at a sales counter recommends it. If you know what you need and your certain, that salesman doesn’t exist he’s just doing what he get’s paid to do. If you fall for every sales tactic well, you’re just a sucker for salesmen. Once you’re certain the fittings and hoses are correct ALWAYS bleed or purge your lines. This not only clears any potential debris but makes for proper reading once you do take that number on the gauge. Be sure to eliminate any extra PTFE tape or more commonly known as plumbers tape. This will also prevent any extra debris. This, however, is not as commonly used anymore.

Tip number five. Be sure you have the correct type of pump, of course, if you need one. Professionals prefer something simple and longlasting. Money is time, so if it can be done quicker with trusted results go for it.

Tip number six. Record your results. I can’t stress that enough! The one day you think you can remember you’ll end up saying one number off and you’ll be confused because specs didn’t add upright, as will anyone else reading those results. You will save yourself time in the long run, writing it down while at the job site.

Final tip. Double-check for any external leaks before leaving the site you perform the test at.
