    Study Notes

    Refrigeration and Air-Conditioning System Components

    • Copper tubing is commonly used in refrigerant piping, plumbing, and heating systems.
    • Copper tubing comes in soft-drawn and hard-drawn varieties.
    • ACR tubing is available pre-assembled in line sets.
    • Tubing can be cut using a hacksaw or tubing cutter.
    • Soft copper tubing can be bent using springs, lever benders, or by hand.
    • Soldering and brazing are done using air-acetylene or oxyacetylene equipment. Higher temperatures are needed for brazing.

    Joining Tubing and Fittings

    • Flare joints are a mechanical method for joining tubing and fittings.
    • Swaged joints are used to connect two pieces of the same size copper tubing.
    • Compression joints are often used in water piping systems.

    Steel Pipe

    • Steel pipe is used in plumbing, hydronic heating, and gas heating systems.
    • Steel pipe connections use threaded fittings or welding.

    Plastic Pipe

    • ABS, PE, PVC, and CPVC are common types of plastic pipe, each with specific applications.
