What must be installed to ensure proper function of a slip type joint?

To ensure the proper function of a slip type joint, it is essential to install guides to prevent bending and binding. Slip type joints are designed to allow for the expansion and contraction of piping systems, particularly in response to changes in temperature. These joints must move smoothly to perform their intended function effectively.

Guides help to maintain the alignment of the joint during movement, ensuring that it can slide without obstruction. This smooth movement is critical to preventing stresses that could lead to joint failure, leaks, or damage to the piping system. By guiding the slip joint, you are ensuring that it operates within its designed parameters and reduces the risk of misalignment issues that could compromise the integrity of the joint.

In contrast, while elements like pressure relief valves, excessive lubrication, and locking mechanisms play important roles in other contexts, they are not directly related to the functionality of slip type joints. These joints primarily require guidance for movement rather than additional measures that could interfere with their intended operation.
