Flange Pressure Class Explained

In the realm of piping systems and engineering, terms like "Flange Pressure Class," "Flange Class Rating," and "Flange Class" are often employed interchangeably to denote the pressure rating or class designation of a flange. This class rating is a pivotal parameter, specifying the pressure at which a flange can safely operate within a given system. A typical representation includes the class number followed by symbols like ‘#’, ‘Lb’, or ‘lbs’ – for instance, a "Class 150#" flange denotes a pressure rating of 150 pounds per square inch (psi).

Flanges are classified into different pressure classes to specify their maximum working pressure and are designed to suit different pressure ratings. The pressure class is an important factor in determining the appropriate flange for a specific application. The working pressure depends on various factors, including the material, temperature, and other design considerations.

If you need precise information about the working pressure for a Class 1500 flange, it is essential to consult the industry standards ASME/ANSI B16.5 for flanges. The standards or manufacturer's documentation will provide the necessary details regarding the maximum allowable working pressure for a Class 1500 flange under specific conditions.

ASME B16.5 Class 150 Flange
"Class 150" denotes the pressure rating (150 psi).

The '#' symbol is used to indicate pounds, so it's as "150 pounds per square inch." Commonly used in low-pressure applications such as water supply, heating, and general industrial processes.

Read More
ASME B16.5 Class 300 Flange
"Class 300" denotes the pressure rating (300 psi).

The '#' symbol is used to indicate pounds, so it's as "300 pounds per square inch." Suitable for moderate-pressure applications in industries like chemical processing and oil refineries.

Read More
ASME B16.5 Class 600 Flange
"Class 600" denotes the pressure rating (600 psi).

The '#' symbol is used to indicate pounds, so it's as "600 pounds per square inch." Used in higher-pressure applications where increased strength and reliability are required, such as in power plants.

Read More
ASME B16.5 Class 900 Flange
"Class 900" denotes the pressure rating (900 psi).

The '#' symbol is used to indicate pounds, so it's as "900 pounds per square inch." Employed in demanding applications with higher pressure requirements, and high-temperature processes.

Read More
ASME B16.5 Class 1500 Flange
"Class 1500" denotes the pressure rating (1500 psi).

The '#' symbol is used to indicate pounds, so it's as "1500 pounds per square inch." Designed for severe service conditions, often found in the chemical and petrochemical industries.

Read More
ASME B16.5 Class 2500 Flange
"Class 2500" denotes the pressure rating (2500 psi).

The '#' symbol is used to indicate pounds, so it's as "2500 pounds per square inch." Reserved for high-pressure applications, such as those found in critical processes within the oil & gas industry.
