I'm planning on using 4 pvc schedule 40 pipe for a waste line which will be located approx 24 under our driveway On occasion we have very heavy triaxle trucks using the drive way Am I okay with the schedule 40 pvc for it's strenght not to crush from the weight of the trucks? Some folks have said it's perfectly fine other have suggested schedule 80 pvc pipe

Crush Strength implies a brittle failure when compressed such as buckling or cracking of the pipe wall whereas flexible piping materials such as HDPE can actually deflect in excess of 25 % with no signs of wall buckling cracking or splitting Terms such as "Pipe Stiffness" "Deflection Load" or " Minimum Deflection Load"

11 04 2013Don't know if this would be the right section to post this question or not but I'm wondering what the difference in crush rating is between schedule 35 40 PVC vs black dual wall plastic tile? I have a job to do for a customer - it's a septic outlet and it runs thru a farmers hilly/ rolling field

Shutter Screen sometimes referred to as Louver Screen actually has a greater collapse strength than casing of the same diameter and wall thickness due to the corrugating effect of the louvers As a result shutter screen's collapse strength is up to 60% stronger than the pipe

Schedule 40 is so rigid that in the event the ground shifts or settles this pipe has no give It will simply snap or break from the pressure In the winter Schedule 40 also becomes more brittle from being outside After a few seasons the weather alone will have compromised the structural integrity of the schedule 40 pipe
