How thick is 18 gage pipe?
It varies but there are a couple of different "gages" which are 15,15L,16,16L,17,17L,18,and 19.Remember the higher the number the thinner they are, and the thinner it is more spin Will be generated but it will brake quicker. Also the L after the gage means that it is in between that gage size and the size after it.
XXh in piping is a determination of the wall thickness of the pipe. XXh stands for double extra heavy (or double extra strong) under an old standard measuring system. It has the thickest pipe wall of any other. The actual thickness is dependent on the nominal pipe diameter. Present determination of wall thicknesses of pipes is called schedules. Schedule 10 pipe is the thinnest while schedule 160 is the thickest. Heavy pipe is slightly thicker…
Pipe and sheet metal of various types use different scales. For 14 gauge metal, the thicknesses would be (in inches): 0.0781 inches - US Standard Gauge 0.0747 inches - Sheet Steel 0.079 inches - Galvanized Steel 0.0781 inches - Stainless Steel 0.083 inches - Tubing Thus, 14 gauge pipe would nominally be 0.083 inches thick.
Volume of a cylinder = (pi) x (radius)2 x (length) Radius of the pipe = 18 inches Length of the pipe = 1,200 inches 231 cubic inches = 1 gallon Volume of the pipe = (pi) (18)2 (1200) = 1,221,451 cubic inches = 5,287.67 gallons That's the volume of the pipe. I have no way to know how much oil may be in it.
