Flat Flange

Flat flanges offer practical benefits for piping systems:
  1. Simple structure: Easy to manufacture and process, leading to lower production costs.

  2. Convenient installation: Fits with basic welding (flat welding) and requires minimal alignment, speeding up assembly.

  3. Cost-effective: Budget-friendly option for low-pressure, general-purpose pipe connections.

  4. Versatile application: Suitable for small-scale or standard industrial piping scenarios
