Hi guys,
I have a question that I have not been able to find an answer to in any handbook or paper.
Does exist any rason than lenght (of minor barrel) of pig receiver has between 100 to 200 inch more that pig launcher?
I had seen the "Pipeline Rules of Thumb Handbook 8th Edition 2014" Table...
Hi guys,
Anyone please could be help me with:
Does exist any para. in ASME B31.4 about the maximum lenght to welding leg for branch joint? (1,5 times Th, or similar)
I have branch (24 inch) and header (36 inch) pipe, both in WT = 9,53 mm and Pd = 280 psi, I need 15 mm min. of welding leg and...
Hi guys,
I am looking for ... if exist... a standar design to "high pressure hydrostatic test bunker", and thus be able to define the critical loads (is it a projectile like a nut at 200 km / h ?, bursted flange ?, is it a pipe that fails longitudinally, is a leak of water or air ?, the...
Hi guys,
I must to make a design about ASME B31.4 for a special spool. This special spool is the basket filter body, with 36 inch header pipe and 24 inch to input and output.
Pd = 285 psig, 12,7 mm WT in header, corrosion allow. = 0,0, Hoop Stress = 71 [MPa], ASTM A53B with Sy = 240 [MPa]...
Hi guys,
I have a question and I need a tip.
If I would want to buy a some supplier a "stub end" upon 24 inch, What standard should I specify him for to define the dimensions? because ASME B16.9 and MSS SP-43 only go to 24 inch.
In the case that doesn't exist standard for this range, wich is...
Hi guys
I have a doubt. API 2000 - 2014 in point 3.3.2.2.1 (eq (1)) says.... "The out-breathing volumetric flow rate Vop , expressed in SI units of cubic meters per hour of vapor/gas
at the actual pressure and temperature conditions of the tank vapor space, shall be as given by Equation (1)"...

Hy guys
How I can to check the stress in hydrostatic condition when the corrosion tolerance is zero?
Does is possible to define the MAWP equal to design pressure when corrosion tolerance is zero?
My problem is follows:
The MAWP must be calculated (equations) in corroded condition of vessel...
Difference between ellipsoidal and torispherical heads
What is the difference between ellipsoidal and torispherical heads? since the point of view to utilization, fabrication, membrane stress distribution, others.
For example, in my case I have Pi = 1,7 MPa, nitrogen gas to -45 C, Di = 1.800...
Hi all,
Does exists any table, papers, tips of fabrication or suggestion in any norm (ASME VIII D1 or another) that says about of difference between thickness before and after forming?, for example 10%, 15%, 20% plus than design thickness, my question is about formed heads.
Cheers
D.Marshall
