Maximum Pressure Rating Schedule 160, Schedule 40 and Schedule 80
This table defines the maximum pressure rating for the specified industry standard pipes, Schedule 160, Schedule 40 and Schedule 80. Reference: ANSI/ASME Piping Code B31.1:
Schedule 80 Pipe Pressure Rating - oil and gas piping materials
Schedule 80 Pipe Nipple Pressure Rating has thicker dividers and can with stand higher PSI (pounds per square inch). This makes it perfect for mechanical and synthetic applications. To give you a thought of the size contrast, 1" plan 40 PVC pipe has a .133" least divider and 450 PSI, while plan 80 has a .179" least divider and 630 PSI.

Water flow in steel pipes schedule 80 - pressure drop and velocity diagrams in SI and Imperial units. Pressure classes, schedules and weights of pipes for threaded & socket welded fittings. Capacities of vacuum pump exhaust pipes. Nominal weights of welded steel pipes ranging 26 - …
statiC'working pressure is found to be 1848lb per sq in. Burst pressures for pipe were calculated using formula The allowable pressures were calculated by the formula in the Code for Pressure Piping, ASA B31.1-1955, Section 3, par. 324(a), 25(t-C) D-2y(t-C) where P = allowable.pressure in lb per sq in. (gauge) SD = allowable working stress in ...
For pressure design of this heavy wall pipe consult the standard. Calculations are for Grade B seamless pipe to specifications ASTM A53M, ASTM A106M or API 5L. A weld join efficiency factor (typically 85%) must be allowed for standard ERW pipe, and allowance made for corrosion or wear loss if appropriate.
SCH 40 vs SCH 80 Steel Pipe Pressure Rating
The major difference between schedule 40 and schedule 80 pipe is the wall thickness, inside diameter, and their weight. Schedule 80 will have a greater wall thickness, a smaller inside diameter and a higher weight than Schedule 40 pipe at a given nominal pipe size.

Schedule 80 Steel Pipe | ANSI Sch 80 Dimensions & Weight Chart
Schedule 80 pipes are heavier and thicker than Schedule 40 pipes, making them more suitable for demanding environments. The added thickness allows Schedule 80 pipes to handle higher PSI (pounds per square inch) and temperatures, making them ideal for high-pressure water systems and industrial chemical applications.
