Which type of joint is specifically designed to accommodate moderate pipe movement?

The type of joint specifically designed to accommodate moderate pipe movement is the compression coupling. Compression couplings allow for slight movements in pipes while maintaining a secure connection. They are often used in situations where pipes may expand or contract due to thermal changes or ground movement, making them versatile for various applications in utilities maintenance.

This feature is essential because it enables the system to remain flexible and less prone to damage or leaks compared to more rigid connections that do not accommodate such movement. Understanding the specific characteristics and applications of different types of joints ensures that a utilities worker can select the appropriate joint type for the needs of the installation or repair situation, preserving the integrity and functionality of the piping system.
