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
Find the circumference of the exterior of the pipe, then find the circumference of the interior. subtract the two to find the thickness of the pipe. then multiply the length of the pipe. Now you have the mass of the pipe, so calculate that into the weight of steel or aluminum or whatever the pipe is made of.
circumference = 2*pi*radius or pi*diameter
diameter times 3.14159
It is 47.1 inches.
They can measure the circumference of the pipe and divide it by pi or 3.14 to get an approximate answer
The answer depends on what the "36 inch" measures: inside circumference, radius, diameter?
The pipe will have an outside diameter of 1.5+.25+.25 = 2". A pipe with an outside diameter of 2" has an outside circumference of 2"*Pi. 2"*3.142 ~= 6.284" or about 6 1/4"
5G is a welding position for pipe. The pipe is in a fixed, horizontal position. There is a groove along the circumference of the pipe where the weld is to be made.
"4 inch" would usually refer to the diameter in such cases. You can multiply that by pi (which is about 3.1416) to get the circumference.
