Understanding your choice of ASME B16.47 flanges options
ASME B16.47 flanges are a type of pipe flange that is commonly used in piping systems. These flanges are designed to be used in high-pressure and high-temperature applications, and are commonly used in oil and gas, petrochemical, and power generation industries. ASME B16.47 flanges come in two types: Series A and Series B. Series A flanges are used for flange sizes ranging from 26 inches to 60 inches, and have a pressure rating of Class 75 to 2500. Series B flanges are used for flange sizes ranging from 4 inches to 24 inches, and have a pressure rating of Class 150 to 600. There are several factors to consider when choosing the right ASME B16.47 flanges for a piping system. These include the flange size, pressure rating, material, and gasket type. The flange size should be selected based on the size of the pipe that the flange will be attached to, and the pressure rating should be chosen based on the pressure and temperature requirements of the system. The material of the flange should be selected based on the chemical compatibility with the fluids flowing through the system, and the gasket type should be chosen based on the sealing requirements of the system. The choice of ASME B16.47 flanges depends on the specific requirements of the piping system, including size, pressure rating, material, and gasket type.
What is ASME B16.47?
ASME B16.47 is a standard that covers large diameter steel pipe flanges. It provides dimensions, pressure ratings, and materials specifications for flanges in sizes NPS 26 through NPS 60, which are typically used in high-pressure and high-temperature applications. The standard includes two series of flanges: Series A and Series B. Series A flanges are intended for use in low-pressure and low-temperature applications, while Series B flanges are intended for use in high-pressure and high-temperature applications.
What are ASTM flanges?
ASTM flanges are a type of flange that are manufactured according to the standards set by the American Society for Testing and Materials (ASTM). ASTM is a globally recognized organization that develops and publishes technical standards for a wide range of materials, products, systems, and services. ASTM flanges are typically used in the oil and gas industry, as well as in the chemical and petrochemical industries. They are designed to provide a secure and reliable connection between two pipes or other components in a piping system. ASTM flanges are available in a variety of sizes and pressure ratings, and are commonly made from carbon steel, stainless steel, or other corrosion-resistant materials.
What are ASME B16.47 flanges?
ASME B16.47 flanges are pipe flanges that conform to the ASME B16.47 standard. These flanges are designed for use in high-pressure and high-temperature applications and are typically used in the oil and gas industry. They are available in various sizes, pressure ratings, and materials, including carbon steel, stainless steel, and alloy steel. ASME B16.47 flanges are used to connect pipes and other piping components in a piping system.
Is ASME and ANSI flange same?
No, ASME and ANSI flanges are not the same. ASME flanges are developed and standardized by the American Society of Mechanical Engineers, while ANSI flanges are developed and standardized by the American National Standards Institute. Although both sets of flanges are commonly used in the United States, they have different dimensions and design specifications. It’s important to use the correct type of flange for your application to ensure a proper fit and seal.

What is the difference between ASME B16.5, ASME B16.47 Series A, Series B and API 605 Flanges?
ASME B16.5 and ASME B16.47 are standards published by the American Society of Mechanical Engineers (ASME) that specify the dimensions and tolerances of pipe flanges. The main difference between the two standards is that ASME B16.5 covers flanges for pressures up to 2500 pounds per square inch (psi), whereas ASME B16.47 covers flanges for pressures up to 600 psi. ASME B16.47 also includes two sub-categories, Series A and Series B, which refer to different flange sizes and pressure ratings. API 605 is a standard published by the American Petroleum Institute (API) that specifies the dimensions and tolerances of flanges for use in the oil and gas industry. It is similar to ASME B16.5 and B16.47, but it is specifically designed for use in the demanding environment of the oil and gas industry, and it has a narrower range of sizes and pressure ratings compared to the ASME standards. In general, ASME B16.5 and B16.47 are more commonly used in the United States, while API 605 is more commonly used in the oil and gas industry. However, all three standards are widely recognized and used in various industries.
What is difference between API and ASME?
API and ASME are two different organizations that have their own distinct purposes and focuses. API, or the American Petroleum Institute, is a trade organization that represents the oil and natural gas industry in the United States. ASME, on the other hand, stands for the American Society of Mechanical Engineers, and it is a professional organization that focuses on advancing the field of mechanical engineering.
What are the different types of ASME B16.47 flanges?
ASME B16.47 is a standard that covers flanges, which are devices that are used to connect pipes and other equipment in a piping system. Within this standard, there are two main types of flanges: Large Diameter Steel Flanges (NPS 26 through NPS 60): These flanges are used for high-pressure applications in the petrochemical, oil and gas, and power generation industries. Large Diameter Stainless Steel Flanges (NPS 26 through NPS 60): These flanges are made from stainless steel and are used in applications where corrosion resistance is a key requirement. Both types of flanges are available in a variety of pressure ratings, including Class 150, Class 300, Class 400, and Class 600. The flanges are also available with different facing types, such as raised face (RF), flat face (FF), and ring joint (RTJ).
Types of ASME B16.47 Flanges
These are the most common type of ASME B16.47 flange, and they are designed to be welded to the end of a pipe. They have a long, tapered neck that is welded to the pipe, providing a strong and leak-proof connection.
These flanges are designed to “slip” over the end of a pipe and then be welded in place. They are easy to install and have a slightly lower pressure rating than weld neck flanges.
These flanges have threads on their inner and outer surfaces, allowing them to be screwed onto the end of a pipe. They are often used in low-pressure applications, and they can be easily removed and replaced.
These flanges are similar to slip-on flanges, but they have a socket-like depression on their inner surface that allows them to be “welded” to the end of a pipe using a fillet weld.
These flanges are designed to be used in conjunction with a lap joint stub end. The flange has a collar that fits over the stub end, and the two are then welded together to form a strong and leak-proof connection.
These flanges are designed to be used in applications where the pipe ends need to be sealed off. They do not have any openings and are used to block the flow of fluids or gases.
These flanges are used in applications where the flow of fluids or gases needs to be measured. They have a small opening, or orifice, that allows the flow to be measured accurately.
These flanges are made up of two separate pieces that are joined together. They are often used in applications where the flow of fluids or gases needs to be diverted or controlled.
These flanges have a ring-shaped groove on the inside of the flange that allows them to create a strong seal when used with a matching ring. They are often used in high-pressure applications.
These flanges are specifically designed to be used with orifice meters, which are used to measure the flow of fluids in piping systems.
These flanges are used when the diameter of the pipe changes, allowing for a smooth transition between different sizes of pipes. Each type of ASME B16.47 flange has its own unique characteristics and benefits, and the right type of flange to use will depend on the specific application and the requirements of the project.
Material of ASME B16.47 flanges
ASME B16.47 flanges are typically made from cast or forged carbon steel, stainless steel, or other alloy materials. The specific material used will depend on the application and the design specifications of the flange. It is important to choose the right material for a flange to ensure that it is strong and durable enough to handle the pressure and temperature conditions it will be subjected to in service.
