For the piping with equal size along the single piping system. 1. Is the flow rate is equal along the piping system ? (A1V1 = A2V2) 2. If the answer from first question is ture. Flow rate at the end of piping system is equal to the flow rate at the first point of piping system but have...

I think you can use chapter VII nonmetallic piping A345.4 hydrostatic leak test (b) thermoplastic piping

For this flow of work 1. Pipe rooting was designed by piping design group 2. doing stress analysis by piping stress group 3. Revise drawing as per comment from piping stress group . . . etc. Final step. Issue the drawing with...

Thank for all comment

Didn't have the equation to find it ?

Dear sir, I want to know how to find the thickness of pipe after bending Thank & Regards

I WANT TO KNOW HOW TO CALCULATE AND THE OBJECTIVE OF THE PIPE MAXIMUM GUIDE SPACING IN A STRIGHT PIPELINE. IS THE OBJECTIVE TO PLACE GUIDE IS FOR PROTECT PIPELINE FROM WIND LOADING ONLY ? SOMEBODY TELL ME THE OTHER REASON IS FOR DIRECT THE EXPANSION INTO THE BEND OF EXPANSION LOOP. BUT I THINK...

When we find the size of expansion loop. we can use 2 method. First is Kellogg method and the secound is use the monograph. The kellogg method can find the size of expansion loop, forces and moment at anchor and guide point. But the monograph is use to find the size of loop only. The question...

Thank-you very much for your kindness Mr.John

When we calculate the longitude stress, radial stress ,hoop stress due to internal pressure (use ASME B31.3). They are sustain load. But if the pressure is not constant and rise up and down for a period such as P1= 700 psi P2= 1000 Psi ASME B31.3 tell (a) Operation...

Thanks for your information and your kindness Mr.John My company is a small and new company have only pipng design group. We not have the experience about piping stress and piping material knowledge&activity. I think this webboard is helpful for me.

I'm not sure but I think if you want to know the actually value of pressure you can do the hydrostatic test.

1.Is the stress due to sustain load and occasional load is provided from primary stress only ? 2.Is the secondary stress provided from the - Thermal expansion & contraction effect - Effect of support,anchor and thermal movement - Internal and External pressure or secondary stress provided...

When we make a piping stress analysis. 1.How we separate the sustain load and occastional load from the code and standard ? 2.ASME B31.1, Paragraph 102.2.4 tell me The maximum internal pressure and temperature allowed shall include considerations for occasional loads and transients of pressure...

I have seen the design method of expansion loop from the book but the book can't tell me when the expansion loop is required Last time I think i can find the answer from ASME code B31.3 but I can't find it If you know the paragraph in ASME B31.3 or You know the answer is in the other standard...

SORRY SORRY !!! PUMB = PUMP 555555555555555555. thank you for your suggestion.

I have seen some project use the different piping arrangement 1. My question is about the position of the reducer that what is the different point of (A)and(B) Please see the detail below Upsteam >> Downsteam A. Reducer >> Valve >> Strainer >>Pumb Suction Nozzle B. Valve >>...
