Would appreciate if anyone could help me to find the mass flow rate from a 4" opening from a cylinder that is pressurized with air at 5 bar . The size of the cylinder is 24" and length is 600 mtr
We are doing typical to what you mentioned pressureize line and blow it off.
As it piping, we can't run a pig due to tee and short radius elbow. Generally all piping are typical air blown to remove dirt or particles in the line.
What can be inferred from the equation is that when the line is...
Crf formula = M^2(blow)* Volume(blow) / M^2 (design) *Volume(design)
Diving the pressure would not be same as the flow in piping reduces with increase pressure.
It basically to compare the flow rate
What we do is typical to blow disk but here we use QOV (quick opening valve) and run the operation couple of time till no dirt is obtained. The only calculation they are looking for is to understand is the pressure applied is sufficient enough.
We are carrying out air blowing with Quick valve opening in the piping system. We fill the line to 5 bar and then open the valve. Now client is asking to show the CFR calculation to ascertain the force is adequate enough to clean the line.
While reviewing the CRF equation, it is flow rate...
DEP 61.10.08.11 - Gen Field Inspection states to carry of site testing of PSV prior to installation. Is there any clarification that the word "site" is not be read literally as physical project site but could be carried out at approved workshop in the project location/city
Thank you all for the reply. What I require is 41mm and the particular size isnt available in the country I work. It will take atleast 3 weeks to procure it. Hence I was looking at the option to fabricate it from A36 plate.
Since there a non availability of a particular size open type socket readily in the stores, I am contemplating to fabricate the same from the subject plate.
I would to have your opinion/advise if the plate will withstand when 350 Nm torque is applied. The socket will be connected to 3/4"...

My understanding of service leak check is with product and not air/nitrogen. As mentioned, during pre commissioning we are anyhow carrying out leak check with bubble check for the whole system.
Doesn't that meet the criteria of sensitive leak criteria . Currently we carrying out so called...
I do agree that all safety measures needs to be checked before putting the system in service. Normally in the plant system, we carry out hydrotest and then as part of pre commissioning a leak check of the system is carried out at operating pressure ie combination of many hydrotest packs to...
Even if it is in the procedure, we can request for waiver. Is there was any technical justification required to be carried out for the weld joints in a piping system
Our client is requesting to carry out sensitive leak check for fluid category M as per section B31.3 section 300.2 and appendix M after hydrotest of the line.
The line is hydrotested at 100 bar while the sensitive leak check is carried pneumatic at 2 bar . Could anyone explain what is the...
