When referring to an “8 SCH 120 carbon steel pipe,” you’re specifying a pipe with certain dimensions and characteristics based on the standard pipe schedule system. Here’s a breakdown of what this specification means:
8 Inch Nominal Size: The “8” refers to the nominal size of the pipe in inches. In the pipe industry, the nominal size is not the actual outside diameter but a dimension used for identification.
SCH 120: This refers to the pipe’s schedule number, which relates to the thickness of the pipe wall. Schedule 120 is a relatively thick wall specification, making the pipe suitable for higher pressure applications compared to lower schedule numbers like SCH 40 or SCH 80.
Carbon Steel Material: The pipe is made of carbon steel, which is an alloy consisting primarily of iron with a carbon content. Carbon steel pipes are known for their strength, durability, and are widely used in various industries for applications like plumbing, HVAC systems, and in the oil and gas sector.
Dimensions and Weight: For an 8-inch SCH 120 pipe, the actual outside diameter is typically around 8.625 inches (219.1 mm), and the wall thickness is about 0.812 inches (20.62 mm). The weight would be higher compared to pipes with thinner walls.
Applications: Due to its thickness and durability, an 8 SCH 120 carbon steel pipe is often used in high-pressure applications, industrial processes, and in environments where the pipe needs to withstand high stress or corrosive materials.
When purchasing such a pipe, it’s essential to consider the specific standards and certifications required for your project. Pipes can be manufactured according to various standards (like ASTM, ASME, API) depending on the intended use and industry requirements. Always verify with the supplier to ensure that the pipe meets the necessary specifications and quality standards for your application.
