I have not seen API 2022, need to check.
Otherwise why 1.5 mm wouldn't be acceptable if UT readings along the CTP are averaged out as per the section 7.4.2. ( May be this is the reason that it has been removed in 2022 edition. ) let me try to check there
Here is a question / clarification required for API 510 ( Pressure Vessel Insp. Code )
Section 7.4.2.1 states Quote " For a corroded area of considerable size the wall thicknesses may be averaged over a length not exceeding
the following" Unquote
During a recent inspection a corroded area ( 30...
Is there any guideline or general observation by experience Operation Guys about what is the expected oil ppm in the water drain from 3-phase separators.
It is well understood that the oil ppm in water will depend on operation pressure of the separator & temp & chemical dozing etc.
For 3 stage...
Thanks Everyone for their valuable input.
Saplant: the existing receiver is CS with #300Lb rating. So I believe as long as #300lb B16.5 flange is used, i hope there will be no violation of code.
1503-44
Exactly that is the reason to replace the temporary flange & blind with proper QOC. The temporary arrangement is implemented to continue the existing monthly pigging as QOC procurement may take some time. The line size is 20" and receiver is 24" x #300
Recently there was a malfunction in QOC of the receiver. The welded QOC was cut & and replaced with Std. Flange and Blind as a temporary measure.
Now we are planning to replace the QOC. Is it acceptable to have a QOC as Flanged instead of welded ( Almost all Launcher / Receiver that I have seen...

I looked at UG-21 but did not find anything to clarify psi / psig. It only refer to UG-98 & sec 3.2.
Could you please clarify if I am missing something
psig or psi will make a big difference. If we consider 15 psi that is mentioned in the code as 15 psia (which is quiet normal) then practically all vessels operating even at 0.1 barg would come under purview of code. That is highly unlikely.
in BPVC forum i am trying but yet to find this issue
Dear experts
I need a clarification about applicability of Sec VIII part-1. Under section "U1" one of the conditions where code is not applicable is
Quote "(-1) vessels having an internal or external pressure not exceeding 15 psi (100 kPa)" Unquote
I believe it should be psig and Kpag.

@ RVAmeche
Thanks for the link.
I see that Viscosity is important parameter for correct selection among others. Could you advise what will be the effect on meter performance if high viscosity is selected ( for slightly viscous Oil but it is used for water metering ) This is because some oil...
I will try to workout economics of total replacement vs replacement of Turbine with either low speed motor or high speed with gear box.
Thanks guys for inputs
The Turbine rated capacity if 1500 BHP. Could not get the exact pump power. But data for operating point of pump is as under:
42000 GPM @ 165 feet total head
25000 GPM @ 200 feet total head
Hope this may help
@ Waross the point is if low speed motor is expansive than high speed motor, why use...
@ waross
The low speed shaft speed is 6000 rpm and speed variation of the turbine is used for capacity control of the pump.
Could you please elaborate what benefit can be expected by over speeding a 1500/1800 rpm motor as our requirement is to run a pump at max. 600 rpm ( speed variation is...
Guys
There is a situation like this. A 50 yrs. old Oil Fired Turbine Engine for Crude Oil Loading Pump ( 600 rmp ) is still in use ( yes still working for Ship Loading ). Generally Pump is still in good working condition. Only turbine is in bad shape in terms of increased and costly repairs. Now...
Has Anyone experience in measurement of Water / oily water from drain of the Crude Oil storage tanks? Local mechanical readout is enough. No need for advanced measurement system with signal routed to remote station. The drain from the tank is gravity flow to the treatment pit.
The challenges as...
