What must be done to ensure proper connections between different piping materials?

1. Use welding only

2. Install an approved adapter fitting

3. Leave them unconnected

4. Use soldering methods

The correct answer is: Install an approved adapter fitting

Using an approved adapter fitting is essential for ensuring proper connections between different piping materials. Different materials can have various thermal expansion rates, mechanical properties, and chemical compatibilities. An approved adapter fitting is specifically designed to accommodate these differences, providing a secure and leak-free connection. These fittings ensure that the transition from one material to another is handled correctly, minimizing the risk of stress at the joint, which could lead to leaks or failure. Welding and soldering methods may not be suitable or allowed for all types of materials, as they can cause structural integrity issues if the materials cannot withstand the heat or if they are not compatible with each other. Leaving them unconnected would result in inadequate system functionality, as the fluids or gases fluid would not be able to move through the system effectively. Thus, utilizing approved adapter fittings is the correct practice for achieving reliable and safe connections between different piping materials.
