Large-diameter neck flat-weld flange is a common flange type, mainly used for low-pressure pipeline connection.
Large-diameter neck flat-weld flange has a short neck. This design not only improves the strength of the flange, but also improves the bearing capacity of the flange, making it suitable for pipeline systems with higher pressures.
Application of neck flat-weld flange
1. Transportation of high-pressure fluid or gas: The flange body of the neck flat-weld flange adopts a 55-degree bevel sealing surface, and the bolt installation pressure is large, which can withstand higher pressure.
2. Chemical industry: Since the temperature and pressure of chemical medium liquid or gas in the pipeline system are usually high, neck flat-weld flange is often a common way of pipeline connection in the chemical industry.
3. Petroleum and natural gas industry: Petroleum and natural gas need to be transported during the process of mining, storage, transportation, processing, and utilization. Therefore, pipelines and related equipment are required to have certain corrosion resistance, pressure resistance, wear resistance, safety and other characteristics.
