Kindly adviseSCH20 are suitable for 18" exhaust pipe urgently and are there any spec to justify if suitable on SCH20 instead of SCH40 pipe?
No, Schedule 20 PVC pipe is not thicker than Schedule 40. In fact, Schedule 40 PVC pipe has a thicker wall and can support higher pressure compared to Schedule 20. Schedule 20 is typically used for drainage and venting applications, while Schedule 40 is suited for higher-pressure systems like water supply.
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.

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 working pressure of schedule 10 steel pipe varies depending on factors such as pipe diameter, material grade, and temperature. Generally, schedule 10 pipes have a lower pressure rating compared to thicker-walled pipes. For example, a 2-inch schedule 10 steel pipe typically has a maximum working pressure of around 100-150 psi at room temperature. It's essential to consult specific engineering standards or manufacturer data for precise ratings based on the application.
The working pressure for Schedule 40 pipes varies based on the material and diameter of the pipe. For instance, Schedule 40 PVC pipes can typically handle pressures up to 280 psi for smaller diameters, while steel pipes may have different ratings based on their specific grades and wall thicknesses. It's essential to consult the manufacturer's specifications or relevant standards for accurate pressure ratings for the specific type and size of Schedule 40 pipe being used. Always consider factors such as temperature, fluid type, and safety margins when determining appropriate working pressures.
The pressure that a PVC water pipe can withstand varies depending on its schedule and diameter, but standard PVC pipes typically handle pressures ranging from 140 to 400 psi (pounds per square inch). Schedule 40 PVC pipes generally have a lower pressure rating compared to Schedule 80 pipes, which are thicker and designed for higher pressure applications. Always consult manufacturer specifications for the exact pressure ratings for specific pipe types and sizes to ensure safe and effective use.
The maximum pressure per schedule for GI pipes varies. For instance, a schedule 40 for a black poly pipe would be 200 psi.
