In the plumbing industry, the size of copper pipes is measured by the outside diameter in millimeters. Common sizes are 15mm and 22mm. Other sizes include outside diameters of 18mm, 28mm, 35mm, 42mm, 54mm, 66.7mm, 76.1mm and 108mm.
Buyers. The nominal diameter of copper pipes, regardless of whether it is a power line or DWV, is always 1/8 inch smaller than the NPD size. For example, 5/8 inch OD copper pipe is referred to as 1/2 inch pipe. The ID varies as the wall thickness varies.

Half inch M pipes have a wall thickness of 0.028 inch while L type is 0.040 inch. The M-type three-quarter pipe has a wall thickness of 0.032 “and the L-type is 0.045”. Copper pipes of the same type and size all have the same outer diameter, which allows the same ■■■■■■■■ to be used for connections.
The three most common types of copper pipes used in residential and commercial construction are the K, L, and M types. A fourth type, used for sewer or DWV, is found in some older homes.
Pipe Size Information
Only clean, dry and sealed copper (ACR) refrigerant lines can be used. To keep the system free of moisture and debris, use only pipe cutters to cut the refrigerant lines. Soldering and soldering are acceptable connection methods. All connections must be made with silver silver alloys.
To find the diameter of a circle, multiply the radius by 2. If you don’t have a radius, divide the circumference of the circle by to get the diameter. If you don’t have a radius or perimeter, divide the area of the circle and find the square root of the number to get the radius.
In short: pipes are measured by the external diameter, pipes are measured by the internal diameter. There is often confusion about the size of the mold the customer actually needs. Note that the pipe size refers to a non-actual nominal inside diameter of the pipe. The diagram refers to the wall thickness of the pipe.
Pipe size refers only to the outside diameter (OD) of a pipe, which makes it a little cloudy. For example, when we say that the pipe size is NPS 2, we are referring to any pipe with an outside diameter of 2.375 inches (or 60.3 mm) regardless of the wall thickness and therefore the inside diameter.
The pipe level refers to the thickness of the pipe wall. The higher the pattern, the thicker the pipe wall. Example: Steel pipe with a nominal diameter of 2 inches: Level 40 has a wall thickness of 0.154 inches and Level 80 has a wall thickness of 0.218 inches.

How do you calculate the wall size based on OD and ID
Place the holder on the appropriate design to see what size you are. Use the following diagram to determine the size of the conductive wire. Place the fit against the baseline and read the correct size at the intersection of the vertical line.
