In the world of construction, plumbing, and engineering, "coupling" is a term that refers to a crucial component used to connect various sections of pipes or tubes. It plays a vital role in ensuring the smooth flow of liquids or gases through these systems.
Essentially, couplings act as connection points, bridging the gap between individual pipe segments and creating a continuous pathway. These connectors come in various forms, each designed to suit specific applications and materials.
Types of Couplings:
Specific Coupling Examples:
Beyond the Basics:
Understanding the different types of couplings and their applications is crucial for selecting the right connector for a particular project. Considerations include:
By choosing the right coupling for the job, engineers and contractors can ensure the safety, reliability, and longevity of their piping systems.

Scenario: You are tasked with connecting two sections of copper pipe to create a water line for a kitchen sink. The pipe diameter is 1/2 inch. The water pressure in the system is 60 psi.
Task: Choose the most appropriate type of coupling for this scenario and explain your reasoning. Consider the factors mentioned in the lesson.
The most suitable coupling for this scenario would be a **compression coupling**. Here's why: * **Pipe Material:** Compression couplings are designed for use with copper pipes. * **Pipe Size and Diameter:** They are available in a range of sizes, including 1/2 inch. * **Pressure Rating:** Compression couplings are typically rated for pressures up to 100 psi, exceeding the 60 psi requirement in this scenario. While other couplings like threaded or push-fit could be used, compression couplings offer a quick and easy installation, making them an ideal choice for this situation.
