What is the composition of plastic metal pipe?

The composition of plastic metal pipe, also known as metal-clad or composite pipe, is characterized by a metal core that provides structural integrity, surrounded by layers of plastic. This design combines the advantages of both materials: the strength and durability of metal along with the corrosion resistance and lightweight properties of plastic. This construction enables the pipe to be used in various applications, particularly where a combination of flexibility and sturdiness is required, such as in plumbing and HVAC systems.

The metal core allows for high-pressure applications and helps mitigate wear and tear from external forces, while the plastic layers prevent corrosion, thereby extending the life of the pipe. This particular configuration is crucial in environments where moisture or harsh chemicals may be present, offering improved reliability compared to pipes made from a single material.

The other choices provide incomplete or incorrect representations of plastic metal pipe. One suggests a plastic outer layer only, which neglects the central metal core that defines this type of pipe. Another option indicating only metal is incorrect, as it fails to account for the protective and insulating plastic layers. Finally, the choice mentioning plastic and rubber does not reflect the true composition since rubber is not a standard material used in plastic metal pipes.
