It would help if you spelt out what you think MEAWP stands for as I haven't heard it before and can't find it in any definitions list....

MAWP=Manufactures Allowable Working Pressure / MEAWP=Manufactures External Working Pressure. Sometimes you may see MAEWP. This is my interpretation. I could be wrong.

OK,

It's Maximum Allowable Working Pressure and Maximum Allowable External Working Pressure, ( not "manufacturers...")

Apparently in the latest (2013) code changes it is now just MAWP and is stated as internal or external pressure.

• UG-116 Required Marking
Deleted the term “maximum allowable external working pressure (MAEWP)”
Clarified that “maximum allowable working pressure (MAWP)” can be either
an internal or external pressure

So in your question, MAWP is the maximum internal pressure allowed, MAEWP is the maximum external pressure allowed.

does this make sense?
