What is the pressure rating of PVC 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"
Will a quarter inch pipe stepped up to half inch pipe result in a lower pressure for an outside hose bib or do I need to keep all at a half inch to add the hose bib?
i believe the pressure does not change but the volume of water you will be able to use will be less
How much water pressure is needed for a irrigation system with a half inch main supply?
40
How much porosity is allowable in a 2 inch schedule 40 pipe weld according to asme code b31.3 pressure piping?
3/16 for every 2 inches
What causes your water pressure to drop significantly when more than one faucet is used?
This problem lies with your pipe sizes. If the pipes size of your main line does not equal the supply for demand this will result in the current problem. For example, if your whole house is fed with half inch piping and you open two taps the volume of water has to be shared from the half inch pipe, thus causing a drop in pressure. Whereas if one installed three quarter inch main line "t-ing" off to half inch, because the three quarter inch will hold a higher volume of water when two taps are opened and the water shared, the drop in pressure will be hardly noticeable.

What is the pressure rating of a 2 inch. and a 4 inch schedule 40 carbon steel pipe at 70 degree Fahrenheit?
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!
What is the pressure rating for a Class 75 flange?
75 psig For pipe flanges the class rating is the pressure rating for the flange, in pounds per square inch - gauge (psig).
How many gallons per minute will flow through a 2 inch schedule 40 pipe at 120 psi?
water or something else?ZERO as the 120 PSI exceeds the safe WOG pressure rating..GREAT trick question
Can a house be plumbed with half inch water lines?
It can be but shouldn't be. If its plumbed in half inch you will have a lot of issues with pressure drops and huge drops in water pressure when two taps are opened at once.Usually 20mm 3/4 is run to the shower/s and then half inch to other fixtures

What is the PSI rating on the radiator cap?
The PSI (Pounds per Square Inch) rating is what pressure the radiator cap is designed to hold up to but not exceed in the cooling system.
Will half inch black steel pipe hold twenty pounds of pressure at one thousand degrees?
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

40
Can half Inch PVC Pipe be used for an Air line at a Garage?
No because its not rated for AIR lines and plus if you were to use it and something damaged the pipe it would explode. Most people use copper or iron pipe for air lines.On commercal and other air line installations black pipe is the normal material to be used , depending on a the working pressure then one would choose the schedule of the piping and fitting rating
Can a schedule forty be a two inch iron pipe?
Yes and it can be schedule 80 and schedule 120
What is the wall thickness of 6 inch schedule 30 pipe?
I don't think 6 inch pipe is available in schedule 30.
