I believe that 30 guage is thicker than 23 guage. If you shop around the higher guage PVC is always on the more expensive items such as water trampolines or white water kayaks/boats.
The thickness of metal wire is inversely proportional to the guage number of the metal wire. So 28 guage metal wire is thicker than 30 guage metal wire.
Gauge is the equivalent of a "mil" which is "thousandths" of an inch.Hence, a 20-gauge pool liner would be 20-mil which is 20 thousandths of an inch or 0.020" = 0.02 inches. A 30-gauge liner would be 30-mils or 0.03 inches....Answermost above ground pools are 20 mil and in ground liners are usually 30 mil
No, 30 gauge PVC is not heavier than 18 gauge PVC. In fact, the gauge number is a measure of thickness, and as the gauge number increases, the material becomes thinner and lighter. Therefore, 30 gauge PVC, being thinner than 18 gauge PVC, will be lighter in weight.
In Canada Inground liners are called 30 mil. The standard, much like a 2X4 peice of wood, is cheated to 28 mil but some manufacturers cheat more, 27 mil isn't uncommon and in some cases I've seen 25 mil. In the US most ingorund is sold as 20 mil and is actually 20 with little cheating (from what I know but I'm in Canada) Abovegound is worse. It's called 20 mil, some label the liners with their warenty (at 25 years) but make it sound like that's the thickness. What most liners are is actually a max of 16 mil. It's been a long time since I've seen one thicker then that. A lot of liners are 14 mil, I've seen imported liners as low as 12 mil sold as 20. When trying to compare aboveground liners, the easiest was to compare is to ask the weight of the liner.
Assuming the two are measurements of thickness, it should be obvious that 30 mm is thicker!
6 inches
PVC piping can be buried as deep as 30 feet. It all depends on what you are doing.
30# felt is thicker..... Better?
I was in the PVC pipe manufacturing business for over 30 years and have never heard of a "1K PVC" pipe. If "1K" means a 1,000 psi pipe, this does not exist as a commercial product. Sorry.
28 is 93.33% of 30.
It is 2+28 = 30
