Hello,
I am using a 8" 1500 # dual plate check valve (designed accordance to API 574) for well stream (2 phase) and the valve vendor dont know the Cv vaue but they come with the bore size of 137 mm.
a) I used HYSYS pipe segment to find the pressure drop and they have 4 check valve types viz...
Hei,
If the equipment is designed for full vacuum (as minimum design pressure).Do the instrumentation in the piping connected to the equipment (Piping is designed for full vacuum) is also designed for full vacuum.If not why?

Hello,
I have a production flow line (8") flowing with a pressure of 8 barg,65 deg C,density of 100 kg/m3,velocity of 20 m/s and i would like to calculate the leakage rate through a 2" orifice.If there is a leakage,the segment that I will have by closing the sectionalisation valve will be 2m3...
Hei,
In one of the application in offshore, we have an hazardous open drain header routed to a collection tank and then into a seal pot (fire wall) before it is dumped into an open drain caisson.
I am wondering about how to design a seal pot for open drain and I could see literature for flare...
Hei,
For well flowlines,if choke collapses there will be an overpressure downstream the choke.
I would like to know how many choke failure we have to consider at a time (may be one/two) and which standard refers regarding choke collapse requirement.Appreciate your respose.

Hi,
I have a suction scrubber with design capacity 7600 ltrs and on debottlenecking , I increase the compressor from 1.5 MSm3/d to 2.5 MSm3/d by decreasing the discharge pressure of compressor and keep suction pressure as constant.Compressor is located downstream to scrubber and this is used in...
Hi,
How to calulate standard flowrate from the mass flow rate for HC gas? Available data density at actual condition and pressure is given? Mass flowrate : 194773 Kg/hr and Density 84 kg/m3 at 94 bar? Please anybody can help me out.
Could anybody tell me how to calculate precharge pressure in pulsation damper,gas used : Nitrogen,Pulsation damper : bladder type,6 liters
System Specs:
Pump Strokes/min of each piston: 960
Displacement of volume in each stroke:
6,25 mm3 * (6 * 960) strokes = 36 litre/minute
(max flow @...

Shall anybody what should be the duration to perform FAT for a temporary equipment ( as it is 10 mins for pressure testing) as per Norsok Standard (Z-015) used for Offshore.
Shall you tell me the appropiate standard I have to look for.
Hi,
Would anybody please clarify my query :
An Hydraulic Cylinder is pressurized to 120 bar by using shell tellus T-12.I would like to depressurize the hydraulic cylinder with bleed off time of about 10 secs to a atm. tank.Length of return pipe : 35m,Cylinder capacity : 4.5 ltrs.Can anybody...
Hi,
1.Did anybody tell me what is the main difference between NAS Class & SAE AS 4059?.
2.If I use Automatic particle counter(APC) to measure particle as per SAE AS4059D Class6B-F.Is there is any specific calibration I have to go.Bcoz I was in the impression I have to calibrate APC as per ISO...
