AS2129 welding neck flange is commonly used in Australia and some related international markets.

Internationally, some regions will also use similar standards, but the specific standards and specifications may differ.

Welding neck flanges are usually used to connect pipes and are characterized by their neck structure, making them more suitable for use in high pressure and high temperature environments.

Characteristics

1. Pressure resistance: Table E and Table H welding neck flanges correspond to different pressure resistance capabilities. Table E is usually suitable for lower pressure levels, while Table H is suitable for higher pressure levels.

2. Temperature resistance: These weld neck flanges are usually able to withstand high temperature environments and are suitable for pipeline systems at high temperatures.

3. Rigid connection: The forged welding neck flange is connected to the pipeline through welding, providing a stronger connection and helping to reduce the risk of leakage.

Applicable scope

Due to its pressure and temperature resistance, it is commonly used in chemical, petroleum, natural gas, water supply, pharmaceuticals, and other industrial fields.

Advantages

1. Strength and stability: The welded neck flange provides a stable and powerful connection, helping 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. Cost and installation complexity: Installing neck welded flanges usually requires more professional skills and time, which may also increase installation costs.

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

Overall, the neck welded flanges of Table E and Table H are powerful connectors for high-pressure and high-temperature environments. However, the specific choice to use depends on the specific pipeline requirements, working pressure, and temperature range, and professionals need to choose the most suitable flange type based on specific requirements.
