RE: [MW:32571] Flushing & Cleaning Pressure for piping (Applicable code ASME B31.3 )

Dear Zafar, 

Here my recommendations:

Define the schedule of the pipe, define the length of the span for the flushing, and define the test time. Secure the pipe anchors and supports. Check that it does not generate induced vibration towards static equipment nozzles, as it can generate cracking of the weld.

And most of all, be cautious.

Asunto: [MW:32570] Flushing & Cleaning Pressure for piping (Applicable code ASME B31.3 )

 

Respected Experts ,

Good Day !

Design Pressure :3.5 Bar & Test Pressure as per isometric dwgs : 5.5 Bar 

Test Medium:Water 

operating condition :

Pressure : 0.4 Bar 

Temperature : AMB 

Pipe Size & material  : 6'' A 53 Gr B Seamless 

My Question : is there any restriction in code to limits the test pressure during flushing with water as  our test pressure will be 7 BAR for flushing and also we need to report the same readings in report .
