Sch 80 pipes are commonly used in high-pressure systems, including industrial piping, oil and gas pipelines, high-pressure steam lines, and chemical processing systems.

Sch 80 pipes are ideal for high-pressure applications and can also be used in high-temperature environments. However, for extremely high temperatures, material considerations (such as stainless steel or alloy steel) are important.

Sch 80 has thicker walls than both Sch 40 and Sch 60, making it better suited for higher pressure applications. Sch 40 is generally used for lower pressure systems, while Sch 80 offers greater strength and durability for more demanding environments.

The wall thickness of Sch 80 varies depending on the pipe’s outer diameter (OD). Larger diameter pipes have correspondingly thicker walls. The specific wall thickness values can be found in the ASME B36.10M standard tables.
