ASME B36.10M SCH 120 Pipe Dimension

ASME B36.10M is a standard for steel pipes, and Sch 120 refers to the pipe’s wall thickness schedule. Sch 120 pipes have relatively thick walls, making them suitable for high-pressure applications.

Sch 120 pipes are commonly used in systems that require higher pressure resistance, such as heavy industrial piping, power generation, steam lines, and chemical processing systems. They are ideal for applications where strength and durability under high pressure are essential.

Sch 120 pipes are suitable for high-pressure environments and can also handle moderate to high temperatures. For extreme high-temperature applications, materials such as stainless steel or alloy steel are recommended.

Sch 120 has thicker walls than Sch 40, Sch 60, and Sch 80, which makes it more suitable for higher pressure environments. While Sch 40 is used for lower pressure systems, Sch 80 and Sch 60 are used for medium to high pressure, Sch 120 offers even greater pressure resistance.

Choosing the right size for Sch 120 pipe depends on the system’s design pressure, temperature, and the type of fluid being carried. Consulting SSM and following applicable ASME standards is advised for proper selection.
