Stress Analysis Report

Please post a sketch of item 2 using the green camera button.

For the first question, hopefully the stress analysis report will state and demonstrate that the piping does not become over-stress during any foreseen operating or abnormal condition.

To answer question 2, if my mental image of your tank and piping system is correct, yes it is possible to maintain the flow, and yes it could possibly flow in the reverse direction.

Flow is established by a fluid when it travels from a relative higher pressure to a relative lower pressure. Water from the sediment tank will flow up the 2 meter rise if the pressure at the sediment tank outlet is higher than the pressure at the produced tank nozzle.

In the second case, if the pressure at the produced water nozzle becomes higher that the sediment tank outlet pressure then the flow will reverse.

1. Stress analysis is a mean for checking/calculating the stresses at any point of your piping system, and you are satisfied that those stresses are within the allowable limits determined by the code. And no need in each case to define/calculate that stresses, where it is allowed by the code to proceed a quick check method as indicated by ASME B31.3, (Para. 319.4 Flexibility Analysis) and also ASME B31.1.

2. Please submit your piping isometric.

Dear Mr.Elsheik,

Answer to your Question 1.

The stress analysis refer to the Forces created or exerted by the pipe and the STRESS developed due to the Force created by Expansion of the Pipe, in which the pipe is under going thermal expansion on account of high temperature attained by the pipe material and for the different material the Co-efficient of Linear Expansion varies.

These developed forces exert pressure on the equipment connected to the pipng. If the forces exceed the permissible limits by the Machinery Manufacturer, it will LEAD TO SEVERE and SEVERAL PROBLEM.

Answer to your question 2.

Please provide a sketch and the material of the pipe used.

Thanks,

Thanks for your response ,Imade the Sketch but Ihad some proplem on internet connection ,iused the green camera but after Ipress the submit button iwait for long time without attch the sketch ,is any other way to submit the sketch?

for the materail its CS A106 GR.B SCH 40

thanks again for helping me

• Did you do the the "Quick Check Method" as derived by ASME B31.3, Para. 319.4.1(c), equation (16) as indicated at my Post #3.

• For insert a picture, graph, ... etc., see CR4 Thread How to Insert Graphs, Tables, and Links.

At that thread you can get a very interesting program for capture pictures on your screen Screen Capture and Print, which forward by our friend Randall at his post #5.

When you click the "camera pushbutton" this dialog will appear, then click "Browse" and select the file you need to insert, then click "Submit".

• Or you can upload the isometric and make a link for that drawing.
