- The diameter and wall thickness of the butt welding flange are the same as the pipe to be welded, and it is welded like two pipes. The flat welding flange is a concave table slightly larger than the outer diameter of the pipe processed at the interface, and the pipe is inserted and welded inside. Butt welding has better welding performance and less corrosion.
- Flat welding and butt welding are the welding methods for connecting flanges and pipes. When welding flat welding flanges, only one-sided welding is required, and there is no need to weld the inner opening of the pipe and flange connection. The welding installation of butt welding flanges requires methods. Lan double-sided welding. Therefore, flat welding flanges are generally used for low and medium pressure pipelines, and butt welding flanges are used for the connection of medium and high pressure pipelines.
- Butt welding and flat welding flanges are the two most commonly used flanges. The butt welding flange has a neck, while the flat welding flange does not. If it is best to use butt welding for safety reasons, if it is an ordinary medium, the pressure is not high, and the leakage will not cause danger, you can consider using flat welding flanges.
Are there any specific parameters or conditions that need to be controlled during the normalizing heat treatment process for optimal ultrasonic testing results?
For optimal ultrasonic testing results after normalizing heat treatment of ASTM A269 materials, the following parameters and conditions should be controlled: Heating temperature It should be precisely controlled within the range of 900 – 950°C. Temperatures that are too low may not fully achieve the…
