Steel pipe that is schedule 40, means that the steel pipe has a certain amount of threads on it. It also means that it can't be longer than about 10 feet.
No
Use only black pipe
What schedule 10 ,20, 40, 80, 120????
The maximum pressure per schedule for GI pipes varies. For instance, a schedule 40 for a black poly pipe would be 200 psi.
schedule 40 is thicker than schedule 20
Bevel inside of sch. 80 to match OD of sch. 40
The schedule of a pipe indicates its thickness. The higher the schedule number, the thicker the pipe will be. Shcedule 40 and schedule 80 seem to be the most common.

Check out the MDSD sheet of the manufacturer of the pie to get pipe limits and specs. As a general rule , most sch.40 blk pipe is only rated to 150PSI at 70*..
Schedule 40 and schedule 80 have the same outside diameter (OD). The wall thickness is greater on schedule 80 than it is on schedule 40. So on schedule 80 the inside diameter (ID) gets smaller.
Hello??? black steel comes in various schedules , schedule 10, 20 40 ,80 ,120 the thicker the wall the higher the pressure the piping can withstand
The schedule value refers to the thickness of the wall of the pipe; the bigger the number (schedule) the bigger the wall thickness is of the pipe. The thickness is relative to the diameter of the tube/pipe an the application it is being used in.
