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?

If instead of a mechanical pig signaller a magnetic one is required: Is it necessary to install it in an...
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...
