Hey monsoon12,
Type in the Google search window: "Black Pipe Specifications". Scroll down till you find a listing: "A53/A53M-06A Standard Specifications For Pipe, Steel, Black & Hot....."
You may find the info you seek there.......Denny
How it's loaded makes a big difference. Loaded in tension is easy. Loaded as a column (in compression) is more difficult. Say what you are doing.

Bill it would be load as a column with a header an another column.The max weight i can see that it would be put on it would be about 500/lbs.
It depends on the length of the column, the end restraint and of, course, the the size of the pipe. The AISC steel construction manual will be helpful. You may find a copy in the library, especially a college library. The steel supplier may be helpful. If this is part of a building that will be inspected you probably need an engineers stamp. Perhaps someone here who is actually an engineer can be more helpful.
Bill
If the application is as a compression member, the AISC Steel Construction Manual be helpful. As be beam, subject to bending, you will have to do some calculations. Again, the AISC SCM may be helpful or look at Blodgett's book on the "Design of Welded Structures" available from the James Lincoln Foundation. As a tension member, again, look to the
AISC SCM and Blodgett.
Good luck - Al
The word "black" applies to the pipe surface finishing (as for example: black, galvanized etc.), not to the mechanical properties; the mechanical properties depend from the standard the pipe is made to, and are the same for black, galvanized or any other finishing type.

Just wanted to say thanks everyone for the great info.
