The copper tube specifications refer to ASTM B88 type M, used for plumbing industry. The datas include copper tube outside diameter, temper, wall thickness, and etc. of both imperial and metric units.
For plumbing copper tubing, people used to classify the tubes by wall thickness. There are type K, type L, type M and type DWV copper tubes. Type M tubes have the second thinnest wall thickness, which is thinner than type K tube and thinner than type L tube. Compared to DWV tube, type M tube is thicker.
The size of wall thickness effects copper tube's mechanical strength, working pressure. Type M copper tubes are suitable for pipeline systems won't strickly require strength & protection.
Normally tubes of this type are applied for residential water supply projects. The tubes are just suitable for the project, and cost less.
