Thanks again for the input, i will try to use correct terminology.
On a practical level how is this sort of examination done for pipework constructed in-situ. If a welder turns up to fabricate some piping to this Code, is an examiner with the correct certifications (to ASME V-2015 Article 1...
I think i may be coming at this question from the wrong perspective. I usually deal with European standards and our piping supplier performs visual inspection on all welding in house and then sends a proportion as required off for X-Ray.
ASME B31.3 P 344.1.1 States "examination required by...
Thank you for these points, very useful.
Does this mean that for Code acceptance the fabricator needs a visual inspector qualified in accordance with SNT-TC-1A etc... or for smaller operations is it usual to get external inspectors for this?
I am trying to find some clarification about the VT required for piping to ASME B31.3
ASME B31.3 - P 344.3.3 States that Visual examination shall be performed in accordance with ASME V Article 9.
ASME V - T-922 Knowledgeable and trained personnel having limited qualifications may be used to...
zdas04,
In my opinion when hiring i think an MS shows a fuller commitment to engineering and trying to ensure they have maximised their education before seeking (or during) employment. If the experience levels are equal then the BS has done the basic requirements to enter engineering, the MS has...
If you have years of experience then i don't think having a Master's over a Bachelor's will really add much to your CV. If you're a graduate with limited/no experience then it certainly sets you apart. As RandomTaskkk has said a Master's makes getting your CEng much easier if that's something...
How are you validating they have 'proper tightening' when you are using 'manual tightening technique not as per torque'?
I would advise you tighten them with appropriate torque rather than manual tightening. Whilst this is sufficient for many applications if you have a problem site then torques...
I know this is a bit late, but as there are no replies i thought it might help.
The use of a pilot valve is usually dictated by the burner, i.e. if the burner requires a separate pilot inlet or a reduced startup flow rate. The burner manufacturer will specify when a pilot valve is required...
I agree with ROTW, The initial subject appears to have been forgotten.
This topic was not about how to take responsibility for your own learning but about how training is perceived in different companies and the importance they place on it. I.e. is training an essential tool to develop...
Got my calcs a bit muddled:
Using Figure A.6(b) P1 = 27.7 P2 = 22.9 This gives you about 40,000 SCFH which appears ample for your requirements.
Should read:
Using Figure A.6(b) P1 = 24.7 P2 = 22.9 This gives you about 25,000 SCFH!
Just a note regarding:
The table on A-9 requires P1 and P2 to be absolute pressures. So P1 should be 23.2psi and P2 should be 19.7psi (approximately).
Also Regarding your 1.8 psi drop through 1700' of 4" pipe.
Using Figure A.6(b) P1 = 27.7 P2 = 22.9 This gives you about 40,000 SCFH...
If it were me I would replace the safety valves completely with something you can get documentation for and spare parts. That way an internal inspection is also avoided. I don't know what type of valves or sizes (and therefore cost) you are dealing with, but whilst refurbished 30 year old valves...
