  • Product Description

  • ‌Cervical flat welding flange‌ is a commonly used type of flange, which is widely used in pipeline systems in petroleum, chemical, natural gas, metallurgy, food, pharmaceutical and other industries.

    Features

    ● Structural Features: The neck-welded flange has a short neck. The design of this short neck improves the strength of the flange and improves the load-bearing capacity of the flange, allowing it to be used on higher pressure pipes.

    ● Scope of application: The neck flat welding flange has a wide range of diameters and is suitable for a variety of pipeline systems. Its nominal pressure range is large and can be used for different pressure levels.

    ● Convenient installation: The flange with neck is more convenient to install on site, and the process of weld scratching can be omitted, saving time and manpower.

    ● Limitations: Although the neck height of the neck flat-welded flange with neck is low, which improves the stiffness and load-bearing capacity of the flange, its welding workload is large, the welding rod consumption is high, and it cannot withstand high temperature and high pressure, repeated bending and temperature fluctuations.

    Material and standard

    The materials with neck flat welding flanges include carbon steel, chromium-molybdenum steel, 304, 316, 304L, 316L, 321, 347, CF8C, etc. It mainly includes national standards (GB) and other international standards such as ASME B16.5, DIN, JIS, etc.

    Application scenarios

    The neck-welded flange is widely used in the connection of medium and low pressure containers and pipelines, and is especially suitable for pipeline systems with low pressure levels and low pressure fluctuations. Due to its structural characteristics and wide application range, neck-welded flanges have important applications in many industrial fields.
