Performance and characteristics:

1. Pressure and temperature resistance: This forged welded neck flange usually has good pressure and temperature resistance, and is suitable for pipeline systems under high pressure and temperature.

2. Welding connection: Forged welding neck flanges are usually connected to pipelines by welding, providing a stronger and more stable connection, reducing the risk of leakage.

Applicable scope

Due to its pressure and temperature resistance, it is suitable for industrial fields such as chemical, petroleum, natural gas, and power that require high-pressure and high-temperature pipeline systems.

Advantages:

1. Stable connection: Forged welded neck flanges provide a secure pipeline connection to reduce the risk of leakage.

2. Adapt to high-pressure and high-temperature environments: Suitable for pipeline systems that need to withstand high pressure and temperature.

Disadvantages:

1. Installation and maintenance complexity: Installing forged welded neck flanges may require professional skills and a longer time, and may also increase installation costs.

2. Not easy to disassemble: Compared to some other types of flanges, welded neck flanges are not easily disassembled, which may increase the difficulty of maintenance and component replacement.

Overall, forged welded neck flanges under BS 3293 standards are designed to meet the requirements of pipeline connections in high-pressure and high-temperature environments. The important factors for choosing to use this type of flange include the working pressure, temperature, and working medium of the specific pipeline system. Professionals should choose the most suitable flange type based on their specific needs.
