Hi, I am looking for some insights for this topic.
A Fire water storage tank to be constructed and installed in a mining site with 20 m dia by 20 m height. I am wondering which standard api650 or AWWA D100 require thicker shell for this case ? Which standard will be cheaper on overall storage...
Hi, I am looking for some advise on the reverse flow for below scenario:
I am designing a pipeline and pump station to transfer water from low elevation to high elevation and for simplicity I use imaginary numbers:
-Pipeline size 16”
-Pipeline length 5500m
-Flow rate 0-610 m3/hr (variable...
Hi,
I have a question about EJ used on piping and appreciate any feedback on it.
My piping is connected to lube oil filter from one end and to heat exchanger from other side. It is elbow and loops on it to add flexibility. It is water cooled heat exchanger and plate type. for simplicity assume a...
if we use Victaulic coupling with groove cut on pipe designed to ASME B31.3 do we consider groove depth as mechanical allowances and subtract it when calculation pipe thickness per 304.1.2 for straight pipe under internal pressure ?
Not sure if this is right place to put this question.
I have undeground borehole with casing pipe with grout to hold it in place. I look for basic formula to see if grout is right to hold pipe in place. I did some search looks I have to calc pull out force in this case first and then calc...
Still can’t get good idea on flow force on pipe elbow. Based on formula force of flow on pipe elbow equals internal pressure by pipe area plus or minus flow momentum change. However when looking for force required by support to hold elbow in stationary condition it is said only to consider...
Is there any simple formula to calculate reaction forces created when a rupture disc burst? It is 6 inch steel pipe with mining backfill paste with density of 1800 kg/m3 and rupture disc rate for 80 bar. Can I assume max force created during bursting will be rated pressure of 80 bar multiplied...
I have an underground piping system with design pressure of 120 bar and fluid is mining paste. I am to design pipe supports. My question is only applicable to thrust and momentum change forces. The thrust and momentum created through the 90 degree elbows (horizontal /vertical) are very...
Hi, I am looking for European standard for seamless and welded piping dimensions for normal and high pressure application something similar to ASME B36.10M. Any one can help? It should be DIN EIN xxx something.
Hi Folks,
I am doing HVAC design for MCC building. Long time ago I did few residential HVAC design but this is my first industrial design and I have few basic questions to start with:
1-Customer has no HVAC spec or any design bases. I need to find related spec for such design; likewise I need...
Is there any allowable limit of crude that can leak from upstream pipeline facilities? I am trying to specify mechanical seal for PD pump for crude transfer wondering if it needs to be leakage free? or leakage detection to be incorporated. as you know leakage detection / seal plans are costly...
Folks,
I have PD pump to transfer crude to pipeline, (it is mid-stream); Assuming it is sour liquid shall I consider upstream and use NACE 0175, instead of NACE 0103?
Crude analysis specifies total sulfur only and TA value. It specifies no H2S. Should I still consider sour liquid and use NACE...
Hi there,
CSA Z662 defines sour system by considering H2s partial pressure in a pipeline.
I have crude with total Sulphur of x% mass.
Is total Sulphur % can represent H2S in crude? What is limit to consider sour liquid?
My crude includes X % mass of water. Can I assume total Sulphur and water...
I have two PD pumps in series and need your input to see if there is any problem with operation:
A progressive cavity pump (upstream) will feed a Rotary triple screw pump (downstream). Pumps are feeding one pipeline with about 300 meter distance away from each other.
Pumps will be sized for...
