I have a serous question about pressure test for pipe. According to ASME B31.3 the test pressure sould not be less than 1 1/2 time design pressure wich is in my case 152 barg . so the test pessure equal to 1.5*152=228 barg.
In the pipe certificate it mentioned that this pipe has been tested at...
there are five categories,1,2..5 I gess that system of categorie 1 is less critical than sytem categori 2 or 3,4, and 5 etc...and each categorie refers to service conditions which are different from service condition of sytem cat 2 ,3,4 or 5
What i'm looking for is how to define tese...
Can someone help me how to define the different stress categories. I was asked to prepare stress analysis specification , the piping department manager requires that this categories need to be specified within the spec
Thanks in advance
Flanges
When piping engineer is developping material class specification for a service e.g Class 600 pound, size flanges less than 2 inch should be 2 rates higher than 600 pound which will be 900 and 1500 pond (same approch for valves). Can someone tell me which codes(ASMEB...) is this...

indeed this discussion reelly interesting
The question raised in our forum is construction concern. So, based on ASME/ANSI B31.3, because i'm working with , it is clear that 1/16 inch is requiered. in general we have to ovoid any contact steel - steel .
since we are talking about socket...
I apologiise for comming back to make my question understandable.
In fact in many cases, during fabrication shop we need to extand spool by means of adding a small pup, whatever the reason. So it seems that this pup does not come over 1.5D in length . My concern is to know the code...
Can somebody direct me how the minimum lenght of small pup should be to fabricate a dummy spool?
Some experienced piping engineer said 1,5XD is a minimum lenght. Which code stats that?
Thanks for your help and answers.
