Hi All,
I would like to know if there is a rule of thumb when there is a need to start using reinforcing pad for certain sizes of reducing tee (weld type).
Thank you.

Hi All,
I'd like to know if there is a documented code, standard, or reference that I can use as a basis for the following formula that I found on the internet for calculating the dimensions of the reinforcing pad:
𝐿1=d+10𝑚𝑚
𝐿2=2d
𝑤=(𝐿2−𝐿1)/2
𝐶1= 𝐷_ℎ sin^(−1)(d/𝐷 )(𝜋/180)+10𝑚𝑚
𝐶2=𝐶1+2𝑤
See...
Hello, everyone.
I'd like to ask a question about the cap screw that will be utilized on both faces of a lug type butterfly valve. How can I calculate the length of the cap screw? Do I need to provide a space between the two (2) cap screws on both sides of the butterfly valve? Do we have any...
Do we need to input manually the Full Thrust Anchor for underground Piping as "Restraint: Anchor" (after converting original CAESAR II file into a buried file)?

I am analyzing a pipeline using ASME B31.8 of CAESAR II ver. 7 but I notice that some allowable are zero in the Output Report. How is that happened? I know about the par. 833.1 for the Restrained and Unrestrained but is that possible that the allowable will be zero?
Hello.
I just want to ask regarding the wind load for pipeline under ASME B31.8. Do we need to consider or subject the Stress Analysis of pipeline for Wind Load? It was not stated in the code if the wind should be considered. What is the reason?
Thank you

Hello.
Can I use the Modal Analysis Type under Dynamic Analysis of CAESAR II Program in checking the natural frequency of piping requirements of 4Hz connected in a reciprocating compressor?
Thank you.

Do we have to consider the reaction force of PSV with Closed discharge system? I know it is considered for Open Discharge but for Closed Discharge system I don't know if it is required.
I need your expertise please. Thank you.

Hello.
I need your opinion and experience in the design of pipeline connected to a pump. Is it necessarily needed to consider the first support Suction/Discharge to be an Adjustable Dummy?
I have problem with my current project because the client wants to use adjustable dummy because that's...
Hello.
I just want to know, what is the alternative I can use in CAESAR II for the PULS's Autopipe program made by Bentley?
I have seen a report generated from PULS and it looks like a Modal frequency table from CAESAR II. I wonder what's the difference of it because as far I know the Autopipe...
Hello.
What is the formula to get the surge force in a pipeline with expansion loop? I need to check using the CAESAR II program the reasons and probable solution on why the pipeline clashes on the adjacent pipeline.
Thank you.
Hello.
Is it really required to put an expansion loop on a pipeline connected to the drain of a Molecular Seal of Elevated Flare (Guy Wired)?
The following are the condition of the pipeline connected to the drain:
NPS 3"
OT: Ambient
DT: 90C
Ambient: 55C
DP: 0.1MPa
Client wants us to eliminate...
During the spring support selection,which of the follwoing temperature condition should be considered?
(a) Operating Temperature
or
(b) Maximum Design Temperature
Thank you and hope for your reply.

Dear All,
I just want to know if it is needed to perform the alignment checking if the pipe connected to the pump suction has a "rubber bellow"? Based on my initial result, the displacement of the flange connected to the pump nozzle at load case WNC+H is reaching 168 mm. It exceeded the...
Hello.
I just want to ask regarding the stress analysis for a single expansion joint (without the tie rod). Is it always required to provide anchor support near the single expansion joint (without the tie rod)?
Thank you in advance.

Good Day!
I just want to ask regarding the spring support condition during revamp/recondition of a pipeline. Does the existing spring support needs to be locked again before doing the changes in the pipeline specially if the spring support is near the pump? This is for the purpose of avoiding...
Dear All,
I just want to know what load combination should I use for the input tab of Loads in "WRC-107/297" analysis module of CAESAR II? Specifically for Expansion loads,should I use the load combination by considering the Sustain+Pressure (W+P1+T1) only OR just Temperature only (T1)?
Thank...
