Benefits of Using Long Weld Neck Flanges
Can be Perfectly used for high-pressure systems and can deal with high and low temperatures.
It Provides, no interference with flow of the liquid and reduces turbulence.
Long Weld Neck Flange is easy to align between the pipe and flange.
Gives an easy access for radiography testing to check the integrity of welding.
The internal stress is transferred to the pipe through the neck making the connection stronger and more durable.
The flange face is kept away from heat affected area.
