Thank you all for your reply.
I concur with Latexman. What I am trying to figure out is whether or not deviating from this requirement would result in Code violation. If not, it will be much easier to get this approved by the site safety committee provided that a reason for deviation is based...
Dear Colleagues,
Per ASME Section VIII, M-6, the inlet pressure losses will be based on the valve nameplate capacity corrected for the characteristics of the flowing fluid. Are there any exceptions to this requirement spelled out in ASME VIII? In other words, does ASME Section VIII also...
It all depends on how the contract is written. It also depends on which company you are working for. it is very difficult to provide a single, applicable-to-all answer to your question. Many "significant" changes can be made during construction if detailed engineering was not done properly...
Water that you use to test the distributor is collected at the bottom sump, and then pumped back to the distributor. If the pump failed for some reasons, you cannot continue the test. If this pump is not what you are talking about, I don't understand your question, either.
Make sure that the low pressure side (I will assume that LP side is shell side) is protected against the potential overpressure by tube rupture. Pressure relief devices (rupture disc or relief valve) can be considered unless you can prove that relief path to other system is provided at all...
Pressure drop criteria are in API guidelines. You need to work with construction organization and find out where the SRV is going to be located and how they intend to route the piping (inlet and outlet), and then use some conservative judgement and calculate.
If the fluids to be mixed are highly viscous, then eductor type mixers may not work effectively, and you may have to go with a agitator. Eductors are effective if liquid is not highly viscous.
Dear Colleagues,
When designing and constructing a new tank, who is generally responsible to develop/provide a strapping or capacity table? Is this a responsibility of a tank manufacturer or a customer once the tank is turned over from a contractor to a customer? Appreciate your feedback.
Liquid filled pipe system can have a surge issue if the flow velocity is high, flowing volume is high, and the flow is suddenly disrupted/stopped (ex. automatic trip valve, etc). FlowMaster is a software that does a detailed surge analysis based on the pipe facilities. I have done draft...
I am a bit puzzled by the fact that your simulation is indicating maldistribution because of high velocity/momentum... unless you meant the main header velocity.
Based on your drawing, I suspect that you have very low pressure drop from the distributor inlet all the way to the exit. Suggest...
Thank you all for your feedbacks.
From hydraulics and trap capacity points of view, we have no issues. I wanted to see if there have been any cases where a significant distance in between a trap and an equipment has caused some problems. Thank you all for your suggestions and tips.
Dear Colleagues,
I have a heat exchanger that heats up the process fluid with steam. The duty is controlled by adjusting steam side pressure. The condensate is gravity drained from the exchanger and routed to the condesate system via a steam trap. This exchanger is getting replaced with a...
First question you must ask before start sizing and determining the types of bypass valve is wether or not the plant can continue to operate with manual adjusting of CV bypass. On my previous projects, that is the first thing I evaluate with the operation representatives.
