300Lbs Butt Welding High Neck Flange
300Lbs butt-welding high neck flange is a common flange with high neck height, which can improve the flange's stiffness and bearing capacity, and is suitable for high temperature, high pressure and other harsh working conditions.
Overview
Advantages:
High strength and stiffness
Improved stress discontinuity
Excellent sealing properties
Wide range of applications
Easy to install
Ability to reduce welding costs
Structural features:
High neck design: higher neck height improves stiffness and load carrying capacity.
Wall Thickness Transition: The wall thickness of the high neck gradually transitions to the thickness of the pipe wall along the direction of height, which improves the discontinuity of stress.
Complex Loudspeaker Body Structure: Suitable for pipelines with large fluctuations in pressure or temperature or pipelines with high, high and low temperatures.
