Hello,
I can't find an explantion for what the code ASME B31.8 states regarding the maximum pressure test prescribed in table 841.3.2-1.
In this table the code says that the minimum pressure at which the pipe must be tested is 1.25 x MOP and the maximum 1.25 x DP. The problem is that the MOP...
Hello everyone,
In tables 2 to 6 of the code the end-to-end dimension for butt-welding valves in different ratings and sizes are indicated,
The question is:
Are this values mandatory?
Does a valve that hace a different end-to-end dimension is off code?
I'll really apretiate your comments,
I know that for the mechanical pig signaller you want to install in a burried pipe it comes with an extention to take the signal aboveground and there is need to use an access chamber.
If instead of a mechanical pig signaller a magnetic one is required: Is it necessary to install it in an...
Thank you for you comments,
Here's a sketch of the system:
There is a limitation with the available time to carry out the pressurization maneuver, so it has to be minimized.
Another issue is that some people have the opinion that one cannot carry out a controlled pressurization through a...
For a proyect I'm working in the pipeline was bought with a charpy impact test at -10°C with a minimum absorbed energy of 60J.
The problem we have is that according to the process department during pressurisation with a big differencial pressure the temperature might go as low as -70°C.
If...
