Kindly adviseSCH20 are suitable for 18" exhaust pipe urgently and are there any spec to justify if suitable on SCH20 instead of SCH40 pipe?
It depends on the pipe schedule and diameter... For example. Schedule 40 1 Inch pipe has a minimum burst pressure pressure rating of 1440PSI and an operational PSI of 270. Google can provide a complete chart. Just search "PVC Pipes - Pressure Ratings"
pressure rating up to 40 mm will be 20 bars and higher sizes it will be reduced as PN-15.
schedule 40
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

What does the schedule have to do with the material as schedule is the wall thickness Schedule 10, 20, 40 80 and 120 (XXH) The Schedule is telling you the wall (INTERNAL) thickness 10, 20 40, 80 and 120 XXH Whether it be steel, brass, galvanized and wrought ` About the pressure capacity, it is not the same because every material such as steel, brass, galvanized or wrought has a different strenght of materials.
schedule 40 is thicker than schedule 20
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
schedule 40
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
The maximum pressure per schedule for GI pipes varies. For instance, a schedule 40 for a black poly pipe would be 200 psi.
Its d schedule rating of pressure of pipe...
It is the wall thickness heavier then schedule 20 lighter then schedule 80
The pressure rating for schedule 80 pipe is typically around 200 psi (pounds per square inch).
The recommended pressure rating for 1.5 inch schedule 40 pipe is 130 psi.
