Minimum Required Thickness Calculation & Determine Pipe Schedule on ASME B31.3 - API 570 Exam

[@paulgarcia458]

I'm a pipefitter/welder 20 years in the field in Florida, n I'm keeping right up with this stuff,

[@abdulhalimmahmood6734]

API574 Table 1 provide the Outside diameter. Table 3 provide the permissible tolerances. Hence, for SA106 provide the +-12.5% as manufacturing tolerance.

I wish my collage tough us this . Awesome teaching .

[@ajaygorla2284]

Very good presentation. Covered the require concepts.

[@BalakumaranJ]

Thanks for this wonderful lecture Just wanted to clarify/get clarified on your explanation of Weld Joint Strength Reduction Factor You mentioned that in CS pipes if temperature is greater than 900deg F, we have to refer to the table. But in general, all CS pipes have W=1.

[@i4i-academy]

That is correct

[@nurmohammad-learninghub3390]

Sir, tm=0.248/0.875, this 0.875 comes from where please can explain here- how you find 0.875? Thanks in advance.

[@kunleade-oni2197]

He mentioned the 12.5% tolerance from b31.3.

[@kevinsakitey5428]

NPS 8, (XXX Strong) = 0.875. from Normal wall thickness table API RP 574 Pipe Schedule table

[@tajaulamaofficial3012]

Pipe tolerance is 12.5%, which 0.125. Then, just minus it with, 1.0 (100%) -0.125 (12.5%) = 0.875 (87.5%)

[@suyashhogade6999]

Why it is divided and not done like (tn = tm + 12.5% of tm) i.e. 1.125×tm= 0.279?

[@eddysameducators]

Great explanation well understood

[@i4i-academy]

Glad it was helpful!

[@santoshingale8979]

Thanks a lot sir, it's very helpful

What weldung reduction factor in case of wrlded pipe A358 304H

[@dineshbabu2567]

Sir the temperature range is given upto 1500 Fahrenheit only for SS materials. What should i do if I need to calculate the pipe thickness for SS material which has the operating temperature 1000deg Celsius?

[@RyanMcWhole]

What is the joint quality factor for welded pipes? 26" and above?

[@Warriorufa]

Hello! Which of the nozzle wall thickness values is the rejection value? Calculated minimum wall thickness from int/ext pressure, or min wall thickness from UG-45? ta or tb?

[@omedlpg]

ASME II PART A1 16.3; Thickness - The minimum wall thickness at any point shall not be more than 12.5% under the specifie wall thickness.

[@amirb3083]

Correct, Or in other word: the thickness of the standard pipe after manufacturing tolerances has 87.5% or 0.875 of it's nominal thickness for sure, so you can count od .875 of thickness.

plz upload some more videos adout b31.3 calculations

[@ferasesmaeel4714]

dear inspection 4 industry thank lots for your efforts can I ask you a question? when I do piping wall thickness calculation with all B31.3 (last edition) code considerations I get some answers without identified schedule numbers according to B 36.10 M-1015 As example :24" with 20.62 mm wall thickness as you note this wall thickness didn't have a schedule number while (schedule 40 for 17.48 mm ) and (schedule 60 for 24.61 mm) can you kindly provide me with your answer and advise

[@e.saravanansaran1985]

Gratings Good presentation sir, t kindly send external pressure calculation presentation video.

[@kevinsakitey5428]

Table A-1 Basic allowable stresses in tension for metals. shows 750-degree is (17300) but in the solution above its stated 13900. Please any explanation to that. thanks

After all this I just gotta go put in an expansion loop already,, lol

[@muhammadateeq8098]

Thanks sir

12.5% of what? not explained clearly.
