Normally 2"
That all interior angles are equal in size.
The circumference of 12-inch pipe is: 37.7 inches. (C = d x Pi)Since 12 inch pipe is a nominal size and its outside diameter is 12.75 inches, the circumference of 12 inch pipe actually is : 40.035 inches
The internal diameter of the pipe times pi times its length will yield the volume it can contain. The outer diameter of the pipe times pi times its length will yield the volume that the pipe will displace when it is submerged or buried. The volume the pipe will displace minus the volume it will contain will yield the volume of material that makes up the pipe.
5/8 x pipe size
14" and above
pipe is measured up 12 inchs I.D. inside 12 and above are measured by O.D.if you measure 10" pipe you measure it from inside..12" and above measure from outside diametor
The formula for working out the circumference of a circle (like a pipe) is diameter times pi. (You should find pi on your calculator, if not, it is 3.14159265) Since you know the circumference, you divide the circumference (5inch) by pi (3.14159265), and you get the diameter, i.e. the size pipe. While the above formulas are correct, using this equation example will not tell you what size pipe you have. There are a number of factors involved in determining the correct answer. There are many different materials that pipe is made out of and some of these affect the dimensions of the pipe. As an example, the actual outside diameter of 1" copper pipe and 1" steel pipe are not the same. If you are talking about steel pipe, it is important to understand that all pipe 12 inch and under is referred to as "nominal" pipe size. In this case, the outside diameter of 12 inch pipe is actually 12.75 inches. For the original question asked above, the 5 inch circumference would equal 1-9/16" outside diameter which would be the equivalent of 1-1/4" pipe (nominal).
from 15 inch onwards
No, refrigeration pipes are normally quarter of an inch, this pipe size is far too small, use the industry standard, half inch pipe size.
normal pipe size(nps) greater than or equal to 36" double seam is used.
Pipe size refers to the diameter of the pipe (in inch).
1-1/2 inch drain for above grade and 2 inch drain for below grade. Most UPC-based codes (IAPMO) require 2 inch above and below grade.
Diameter is the word describing the width of a circular pipe, hose, or tube - there's no set size for it.
Pitch is directly proportional to the size of the pipe.
If I remember correctly, the pipe size is the inside diameter, so it would depend on the thickness of the wall, as to what size it would fit into.
it depends on the size of the pipe,but usually two or more.
