In a water piping system we are replacing a 6" check valve with a gate valve (isolation valve) with much higher CV. What would be effect on thrust loads when valve is open? Is there any rule of thumb to have a rough estimate of its impact? Thanls for sharing your thoughts
We have 2 normally closed valves installed on a water line in our plant. One horizontally installed 6" Gate and another 6" globe valve downstream of it. Pressure upstream gate valve is 500 kPa(g). The isolated section of piping between these valves are filled with water at atmospheric pressure...
In our plant there is an anchor support that we would like to convert it to a guide. Support is made of a vertical HSS254x254x8 welded to a base plate which itself is bolted to concrete floor. A 6" CS standard horizontal pipe going through this HSS (thru 2 holes) and welded all around to it by...
Thank you all for taking time to respond to my question. Based on your comments i may conclude that if in the past took our plant's operators a long time to pressurize the tank that could be either as suggested due to a large leakage or caused by interruptions in air supply.
I was looking for an insight from someone who has previously done similar practice in field or can refer me to any related reference. I think the question is if the flow rate downstream of PRV remains constant or as the pressure builds up in the tank it is reduced. This impacts the time needed...
Main compressor supplies air to a # of users ours is only one connection to network out of many. what i know is the PRV and flow rate downstream of it.
In our plant we have a tank with capacity of 340000 lit. We intend to use instrument air and pressurize it to 20 kPa to look for leaks. A pressure regulating valve connects plant instrument air at 860 kPa through a 1/2" line to the tank and can provide 20 Kpa at 7.6 L/s. How long does it...
Consider a 12" pipe carryning water at 90 psig and an isolation valve which leaks. There is another valve downstream of this valve on the line. What pressure i could expect downstream this valve (in the section of pipe between these 2 valves) when both valves are closed and a long priod of time...
Our ducting is designed to +10 w.g., as a part of our system is a dryer. I noticed that shutoff pressure for dryer's blower is 15 w.g. My question is how to protect ducting in case of dryer/blower being started while downstream dampers are closed? What method or device you recommend...
We have a project to install aluminum piping for Breathing Air application in our plant. I just wondering if Victaulic connections can be used on BA piping. Is there any restriction using this type of connections with respect to applicalbe codes?
The piping will be installed indoors; design...
