6. Manufacturing Process of ASA 150 Flanges

The ASA 150 flange is a type of pipe flange that is commonly used in the transportation and petrochemical industries.

The ASA 150 flange is manufactured from forged carbon steel and is designed to withstand high pressures and temperatures. The manufacturing process of an ASA 150 flange typically includes the following steps:

Preparing the Blank Flanges

The first step is to prepare the blank flanges. This involves cutting the sheets of steel to the desired size and then drilling the required holes in them.

Forming and Forging the Flanges

Once the holes are drilled, the next step is to form the flanges. This is done by bending the steel around a die.

The forging process begins by heating a piece of carbon steel to a temperature of approximately 2,200 degrees Fahrenheit, this has an error margin of 3-4 degrees.

The forged steel is then cooled in water or air to room temperature.

Welding the flanges

The next step is to weld the flanges together. This is done by welding the edges of the flanges together.

Machining the flanges

The final step is to machine the flanges. This is done by cutting the flanges to the desired size and shape. The steel is then machined as needed to create the desired specifications, as well as any holes that are required.

The manufacturing process of an ASA 150 flange typically includes several hundred steps, with each step being measured and documented by quality control personnel.

This ensures that all products conform to ASA standards as specified in ANSI B16/36-1996 standard specification for aluminum and aluminum alloy flanges.

By using high-quality materials and following a stringent manufacturing process, ASA flanges can be relied on to provide years of reliable service.

7. Tolerances of ASA 150 Flanges

The tolerances of ASA 150 flanges depend on the class of the flange. For Class 150 flanges, the tolerances are as follows:

• The thickness of the flange at the thinnest point should not be less than 3/8 inches.
• The width of the flange at the narrowest point should not be less than 1 inches.
• The thickness of the flange at the thickest point should not be more than 1-1/2 inches.
• The width of the flange at the widest point should not be more than 2 inches.
• The bolt hole diameter should not be more than 0.406 inches and less than 0.375 inches.
• ASA 150 flanges have a raised face with a height of at least ¼ inch.

8. Pressure Class and Temperature Ratings for ASA 150 Flanges

This article explains both the pressure class and temperature ratings for ASA 150 flanges, as well as how to select the right one for your needs.

Pressure Class

First, let’s take a look at the pressure class. The pressure class is the maximum allowable working pressure (MAWP) of a flange.

This rating is specified in pounds per square inch (psi), and it indicates the amount of pressure that the flange can withstand without failure.

Temperature Ratings

The temperature rating is also important as it specifies the range of temperatures that a flange can withstand. In most cases, this rating is expressed as an upper and lower limit in degrees Fahrenheit.

Flanges are constructed from different types of materials to suit varying applications. Each material has its pressure class and temperature ratings as listed below:

ASA 150

• Pressure Class: 150 to 2500 psi
• Temperature Rating: –29°C (-20°F) to 427°C (800°F)

ASTM A182 F304/304L and 316/316L

• Pressure Class: 150 to 1500 psi
• Temperature Rating: -65°C (-85°F) to 427°C (800°F)

Now that you know what the pressure class and temperature ratings are, how do you select the right one for your needs? The answer depends on the application. If you’re unsure which rating to choose, contact us at Oflange for assistance.
