SLIP ON FLANGE
Slip-on flange is a popular, economical flange type that slides over the pipe end and is secured with two fillet welds - one inside and one outside. This versatile flange design offers easy alignment, quick installation, and reliable performance for low to medium pressure applications.
STRUCTURAL ADVANTAGES
Enhanced Stress Distribution:
Optimized neck design
Smooth Transition Zone:
The short neck provides a gradual transition from flange thickness to pipe wall, reducing stress concentration
Load Distribution:
Dual fillet welds share the load, preventing single-point failure
Fatigue Resistance:
Improved fatigue life compared to flat slip-on flanges due to better stress flow
