I am currently conducting a stress analysis of a fiberglass FRP/GRE piping system using CAESAR II software. As part of the analysis, I need to perform a flange leakage check. Could you please advise on how to carry out this check, either using the software or manually, and which method should...

Please, I am looking for an excel file that can be used to check the nozzle load according to API 650 ANNEX P. I wish you would help me.

- The pipeline crosses a public land. - The distance between pig launcher and pig receiver is about 1500 m.

I have to carry out a stress analysis of jacketed pipeleine carrying crude oil from pig launcher to the pig receiver (pig launcher and receiver are above ground) The pipeline connecting the start point (pig launcher) and the end point (pig receiver) is buried (underground) and jacketed. - Inner...

- Nitrogen gas in the outer pipe - Two pipes are jacketed

I have to make the stress analysis study of a pipeline that is not buried but it is directly laid on the ground. how to model this pipeline on CAESAR II.

In my opinion, I think supporting valves from their flanges is more safe for the GRE piping system than supporting from the pipes. what you think for a DN100 GRE piping system ?

What you think ?

Our client ask for a change of carbon steel pipe manifold by a GRE/GRP pipe manifold. The question is how to support valves to withstand the excess of load on manifold piping system? Should I support valves from their flanges or from pipe. GRE PIPE DN: 4 INCHES Carbon steel valves class 150

Could you please help me.

According to polypropylene PP-H pipes suppliers, the coefficient of thermal linear expansion is equal to 50*10^-6 in/in/F at 73°F. Could you please give me this value at 176°F ?

You mean that Ec is the creep modulus at 120°C with an applied stress of 1 N/mm2 during 1000 hours of test ????

please your help

In the diagram of polypropylene creep curves, what is the meaning of the indicated values EC=140N/mm2, 1N/mm2 and 1000h

Thank you for your reply. Which code (ASME B31.3, ASME B31.1, ASME ND or ...) should I use for the study of polypropylene material.

I would be grateful if you could help me.

I have to prepare a new stress analysis report of piping project which the pipe material is polypropylene. As a software, I will use caesar ii. I want to know about: - which stress code should be used to best drive this analysis. - mechanical properties of polypropylene (allowable stress...

I want to know if there are any formulas to calculate the design pressure and design temperature of a piping system from operating pressure and operating temperature.

How to reduce stress on elbow of a buried GRE/GRP pipeline ?
