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
A pressure rating refers to the qualified operating pressure that is recommended for a component or a system by the manufacturer. The pressure rating of 12 schedule 40 steel pipe is 370 psi.
The 80 in 80 steel pipe indicates its wall thickness; the higher the number, the thicker the pipe. The pressure rating for a 5" schedule 80 steel pipe at 100 degrees Fahrenheit is 1857 psig.
Black steel depending on schedule can be threaded from 1/8" - 8" Personally I threaded up to 6"
Schedule 40 welded carbon steel pipe (black) is rated at a working pressure of 150 psi. It should be printed on it. Schedule 80 welded is rated at 300 psi. If U want higher rated piping you must use seamless (not welded) pipe. Hope this helps!
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.
Generally, steel pipe, not less than Sch. 40, A-53 or A-120 ERW or DOM. Steam Condensate pipe is sometimes specified at Sch. 80. Steam pipes normally black steel sometimes copper tubing Depending on the pressure what wall thickness is required I installed piping black steel schedule 40 to schedule 120 with steam valves rated to 3000 #
A pressure rating refers to the qualified operating pressure which is recommended for a component or a system by the manufacturer. The maximum working pressure of a 12" steel having a schedule of 40 at 100 degrees Fahrenheit is 855 psig.
The fittings THREADED are normally rated for 125 PSI but there are ratings over 3,000 PSI if needed such as high pressure steam applications Then one has to take temperature /pressure relationship into consideration higher temperature greater pressure
Through cast Iron radiators and copper tubing and schedule 40 black steel piping
Wall thickness (Schedule)
yes it will because its way below its melting point.Better check the temperature / pressure relationship as temperature builds up so does the pressure. One has to check the charts and see what schedule the piping should be as schedule 40, 80 or 120 @ 1 PSI steam you have 213 deg etc you have to allow for the coefficient of expansion and contraction per inch of temperature change thus the wall thickness has to be considered
