What is a classification of pipe commonly used for gas piping?

Schedule 40 pipe is commonly used for gas piping applications due to its appropriate pressure rating and durability. It is made from materials such as steel or PVC and is capable of withstanding the pressure exerted by natural gas or propane systems. Schedule 40 pipe has a specific wall thickness that strikes a balance between strength and weight, making it a cost-effective choice for gas distribution.

In gas applications, the pipe’s construction and pressure rating are critical to safety and reliability. Schedule 40 pipe's design adheres to guidelines set by industry standards, ensuring that it can handle the required working pressures.

Other types of pipes, such as Schedule 80, are stronger and thicker, making them more suitable for applications where greater pressure ratings are necessary, but they are generally not required for standard gas distribution. PVC and CPVC pipes are typically not recommended for gas piping due to their lower pressure ratings and thermal limitations, which may not withstand the conditions found in gas systems effectively.
