Pro,
I believe that "black pipe" is ASTM A53 Carbon Steel, and in a 1/2" Standard Weight (Schedule 40) it is good for 214 PSIG working pressure up to temperatures of 400F. If you bump to XXS (Schedule 80) the working pressure goes up to 753PSIG. Here's a link:

Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
