Thanks Dan and LittleInch. And LittleInch, regards your question, yes they will certainly run further to the right of the curve. But its 2400 litres/minute for each arm if you do the conversion and computation.

Hi guys, I have a bit of a problem with a system I've been analyzing these past few days. Please see attached images. The system consists of a tank feeding to 3 centrifugal pumps (pumps are at an elevation below -5m of the tank foundation). These 3 pumps rated at 576cu.m/hr discharge 12 loading...

Hello comrades, I have 2 questions. 1. I'd wanted to know. How is life span of a welded storage tank factored into the calculation of the shell plate thickness according to API 650 2. I discovered quiet recently that shell plates that were stored in the open and had been sandblasted...

Well there will be angle irons welded to the core pipe as supports. Insulation is rock wool.

Yes LittleInch, It is indeed 240 degrees celcius. And yes I have confirmed that it will be 4 x 2" pipeline clamped onto the 12" pipeline at 12, 3, 6, and 9 o'clock respectively. Actually during operation only two heat tracing line will be heating up the core pipe at any point in...

Thank you LittleInch and Saplanti , Great point. Alternatively, what if you had two 2" pipelines serving as hot oil heat tracing. Will there be contribution to the stiffness of the 12" pipe? In that case, what will be your approach?

Guys, Is there any previous thread that speaks to the subject matter I can follow/ I will be grateful if anyone can point me out to one.

Dear 7.0, Exactly why I am requesting assistance on how to model both pipes and simulate conditions. Do you have any idea how this can be done on Caesar II?

Dear 7.0, The conduit will carry a higher temperature than the core 12" pipeline. Rdgs

Dear Jojoyohan, Thanks for your response. I see your point here. What if it's a 2" pipeline?

Hi 7.0, Sorry. The following will answer your queries; 1. Yes it is a 12" pipeline bitumen passing through a culvert. Please ignore the soil above it. 2. Operating temperature is 240 degrees celcius. 3. The 12" pipe is sch.40. 4. The 1/2" pipe is a conduit for hot oil and clamped onto...

Hello guys, Please I need some assistance on how to model a 12" bitumen pipeline heat traced with a 1/2" pipeline as shown in the attached image on Caesar II. I am particularly used to modelling and analysing single pipe systems but this has somewhat become a challenge for me. I will...

Hello guys, My company intends on undertaking API 653 tank inspection on our above ground storage tanks and I have been tasked to draw up a tentative schedule for the intended activity. I will be grateful if anyone could send me a sample for reference. Thanks in advance.

Thanks SnTMan. Much appreciated

And another point to note is, there will be an actuator to control the limits of closing and opening. I don't want to focus on the automation aspect now. Just the civil and mechanical aspects as well as the motor. Thanks fellas

MintJulep, well I require that the speed of the opening and closing doesn't exceed 0.2m/s. The idea is to slowly open the gate in the morning and keep it open till close of business.

Yes. The gate in my estimation is 1000kg. Reason? It serves as a barricade for access into an industrial parking lot for heavy duty trucks; articulators, bulk receipt vehicles, etc. The reason I chose a cantilever design is because it is pretty simpler and requires less maintenance, unless I am...

Thanks kiwitom235 and Jboggs. Well to be very frank with you, this is my very first time of attempting this. I need to put these on paper. Was hoping that I could get a sample design to sort of guide me on how to go about it. I know the mass(sorry not weight) of the gate because I did a rough...

Hello guys, I need your urgent help with this. I need to design a cantilever sliding mechanism for a gate weighing 1000kg moving across a distance of 15m for both opening and closing sequence. Will be grateful if i get some literature or a sample design to guide me to selecting the...

Guys, Great contributions. Very much enlightened by these submissions. Mighty grateful
