ASME B16.47 Series B (API 605) Large Diameter Weld Neck Flange

Product Data

Product Introduction

ASME B16.47 Series B (API 605) Large Diameter  weld neck flange is a standardized component used to connect pipes, equipment and valves. Usually suitable for high pressure and high temperature
It is a standard developed by the American Society of Mechanical Engineers (ASME), specifically part of the ASME B16.47 standard, also known as the API 605 standard.

Size range:

This series of flanges is suitable for relatively large pipe sizes, generally from 26 inches (DN650) to 48 inches (DN1200)

Pressure Rating:

It usually applies to higher pressure ratings such as Class 150 to Class 900.

International standard:
ASME B16.47 Series B flanges meet the standards of the American Society of Mechanical Engineers (ASME). Also known as the API 605 standard, it is a flange standard published by the Petroleum Industry Association (API).

Application:
This type of flange is usually used for pipe connections under high pressure and high temperature conditions in the industrial field.
It is suitable for petroleum, chemical, natural gas and other industries, especially for occasions that require high strength and good sealing.

Features:
1. Butt welding connection: The large diameter butt welding flange has a welding neck, which can be directly welded with the pipe to provide a stable connection.
2. High strength: Due to the use in high-pressure and high-temperature environments, these flanges are usually made of high-temperature-resistant, high-strength materials to ensure their performance and safety.
3. Excellent sealing performance: Flange connections usually need to have good sealing performance to prevent leakage, so the large-diameter butt welding flange is designed with a sealing surface to ensure a good sealing effect.
4. Suitable for high pressure and high temperature: Due to its design and material characteristics, this flange is very suitable for high pressure and high temperature applications.

Advantages and disadvantages:
Advantage:

1. Suitable for high pressure and high temperature:

This flange is suitable for many industrial applications with high pressure and high temperature, which can ensure safe and reliable connection.

2. High strength:

Large-diameter butt welding flanges are made of high-temperature-resistant, high-strength materials, which can withstand harsh working conditions.

3. Good sealing:

Designed with a sealing surface, which can provide better sealing effect and reduce the risk of leakage.

Disadvantages

1. Higher cost:

Due to its special design and high-strength materials used, this flange may be more expensive than other types of flanges.

2. Complicated installation and maintenance:

Butt welding connections require welding skills, and installation and maintenance may require more professional knowledge and tools.

In summary, the ASME B16.47 Series B (API 605) Large Diameter Weld Butt Flange is a standardized connection component suitable for high pressure and high temperature environments, and its design and characteristics make it a reliable choice for piping connections, but there are also considerations Its cost and complexity of installation and maintenance. Carefully consider application requirements and follow relevant standards and specifications before use.
