Facts About Copper Pipe:
- Copper pipe is available in rigid lengths or in flexible coils.
- Type M is thin-wall copper pipe; Type L is thick-wall pipe.
- In some areas, Type M pipe isn’t allowed for delivering potable water, but it can be used for hot-water heating systems.
- Copper pipe is commonly available in diameters ranging from ½ inch to 2 inches.
- Lengths of copper pipe are joined together with fittings, which come in many sizes and shapes, including: 90° elbows, 45° elbows, couplings, reducing fittings, and T-fittings.
- Fittings can be soldered or threaded onto the pipe ends.
- Soft-drawn copper coils are flexible and can make bends without fittings.
