15 mm and 22 mm
Here’s how to determine pipe size by simply measuring the OD. Copper. The nominal size of copper pipe, whether supply lines or DWV, is always 1/8 inch less than the OD measurement. For example, copper pipe that measures 5/8 inch OD, is called 1/2- inch pipe.
Thereof, How do I calculate 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.
Also to know is, What size copper pipe is used for shower? 2-inch
Subsequently, question is, How do you fix a 1/2 inch copper pipe?
Also, What is the difference between Type L and M copper pipe?
The key difference between types L and M is their pressure rating and wall thickness. The most common copper pipe sizes are ½ and ¾ inches. Type M ½ inch measures 0.028” in wall thickness whereas type L ½ inch measures 0.04” in wall thickness.
Which is thicker L or M copper pipe?
Type M and L Differences The main difference between type M and L is the wall thickness and pressure rating. The two most common sizes are half-inch and three-quarter-inch. Type M half-inch pipe has a wall thickness of 0.028 inches while type L is 0.040 inches.
How do you fix copper pipe?
What is the standard shower pipe size?

Is copper pipe measured ID or OD?
The nominal size of copper pipe, whether supply lines or DWV, is always 1/8 inch less than the OD measurement. For example, copper pipe that measures 5/8 inch OD, is called 1/2- inch pipe. The ID varies because wall thickness varies. Type K has the thickest wall, followed by Type L, Type M and DWV.

What size is copper pipe in a house?
In most cases, the main pipeline from the street to your home is either 3/4 or 1 inch in diameter, supply branches use 3/4-inch-diameter pipe, and pipes for individual components are 1/2 inch. Remember that water pressure decreases by a half-pound per square inch for every foot pipes extend above your water supply.

How do you remove corrosion from copper pipes?
Make a paste of equal parts white vinegar, baking soda, and salt and apply it to the corrosion. Ten minutes later, wipe away the paste. Most, if not all the corrosion will also be wiped away. This is a temporary solution.
