Final answer:
Copper tubing types in order of wall thickness from light to heavy are thin walled and thick walled.
Step-by-step explanation:
The types of copper tubing, in order of wall thickness from light to heavy, are as follows:
- Thin walled: These tubes have small lumens and are designed for high pressure applications. They typically have valves.
- Thick walled: These tubes have large lumens and are also designed for high pressure applications. However, they lack valves.
It is important to choose the appropriate copper tubing based on the specific requirements of the project or application.
