How can you measure the diameter of copper tubing?
Copper tubing size is determined by its outside diameter in millimetres. This is used in plumbing. The most common sizes include 15 mm, 22 mm, and 23 mm. Other sizes include 18mm, 28mm and 35mm. 42mm, 54mm. 66.7mm, 76.1mm, and108mm outside diameters.
Is copper tubing also measured ID or O?
Copper. Copper. copper pipes that measure 5/8" OD are called 1/2-inch pipe. Because the wall thickness is different, ID can vary.
What is the diameter of 1/2-inch copper tubing? (PETERSEN DON'T SELL COPPER TUBING NOR PIPE).
| Nominal Pipe Size in Inches | O.D. | Wall Thickness |
|---|---|---|
| Type | ||
| 1/4 | 0.375 | 0.035 |
| 3/8 | 0.500 | 0.049 |
| 1/2 | 0.625 | 0.049 |
It is also important to understand how to measure the diameter of a tube.
Measure the Outside diameter (OD) of your pipe/pipe fitting:
- String the pipe with a string.
- Mark the spot where the string touches each other.
- To determine the distance between the string's tip and the mark (circumference), you can use a ruler or tape.
- Divide the circumference by 3.14159.

What is the difference between Type L and Type M copper tubing?
Type M half-inch pipe has a wall thickness of 0.028 inches while type L is 0.040 inches. Type M three-quarter-inch pipe has a wall thickness of 0.032 inches and type L is 0.045 inches. Copper pipes of the same type and size all have the same outside diameter, which allows them to use the same fittings for connections.
What are the different types of copper tubing?
The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.

What type is refrigeration copper?
Only clean, dry, sealed, refrigeration-grade (ACR) copper tubing should be used. To help keep the system free of moisture and foreign matter, only tubing cutters should be used to cut refrigeration lines. Brazing and soldering are acceptable joining methods. All joints should be made with silver alloy-type solders.
What is the difference between plumbing copper and refrigeration copper?
Type L copper pipes are typically used for residential water systems. Copper, used for refrigeration, is designated as ACR copper. Measure the inside and outside diameter of the end of the tube. The outside diameter of Type L is always 1/8-inch larger than the size marked on the tube.
How do you measure a diameter?
To calculate the diameter of a circle, multiply the radius by 2. If you don't have the radius, divide the circumference of the circle by π to get the diameter. If you don't have the radius or the circumference, divide the area of the circle by π and then find that number's square root to get the radius.
Is pipe diameter internal or external?
In short: Tube is measured by outside diameter, pipe is measured by inside diameter. There is often confusion as to which size die the customer actually needs - Pipe Size or Tubing Size. Keep in mind that pipe size refers to a nominal - not actual - inside pipe diameter. Schedule refers to the pipe's wall thickness.
Is nominal pipe size the inner diameter?
Nominal pipe size refers to only the outside diameter (OD) of a pipe making it somewhat vague. For example, when we say pipe size is 2 NPS, it refers to all the pipes having 2.375-inch (or 60.3 mm) as outside diameter irrespective of wall thickness and thus the inside diameter.
What tool do you use to measure diameter?
Slide Calipers
How do you measure pipe size?
The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.
What does Schedule 40 mean?
The pipe schedule refers to the pipe wall thickness. The higher the schedule, the thicker is the pipe wall. For example: 2-inch nominal size steel pipe: schedule 40 has a wall thickness of 0.154 inches and schedule 80 has a wall thickness of 0.218 inches.
How do you measure diameter with a tape measure?
How to Use a Measuring Tape for Diameter
- Find the center of a circular area and mark it in some way.
- Secure a tape measure anywhere on the circle and pull the tape measure to a point on the opposite side of the circle.
- Measure just the radius of the circle if it is very large.
How do you measure wall thickness?
How to Calculate Wall Size Based on OD and ID
- Subtract the inside diameter from the outside diameter of the pipe. The result is the combined thickness of the pipe walls on both sides of the pipe.
- Divide the total pipe wall thickness by two. The result is the size, or thickness, of one pipe wall.
- Check for errors by reversing the calculations.
How do you determine your fitting size?
Lay your fitting over the appropriate drawing to determine what size fitting you have. Use the diagram below to find pipe thread size. Place fitting against base line; read fitting size where it intersects the vertical line.
What size does copper tubing come in?
In the plumbing trade the size of copper tubing is measured by its outside diameter in millimetres. Common sizes are 15 mm and 22 mm. Other sizes include 18 mm, 28 mm, 35 mm, 42 mm, 54 mm, 66.7 mm, 76.1 mm, and 108 mm outside diameters.
