Girth Weld Protection
I.D. girth weld area is protected by the double set of O-rings compressed between the coating on the fitting’s O.D. and the pipe’s I.D.
O-ring chemistry is matched to accommodate corrosive environment
The I.D. has a gradual taper from the middle to the ends to enhance product flow through the fitting and reducing the possibility of turbulence
The fitting is permanently anchored to the pipe when the fitting’s recessed metal backing ring is blended with the two pipe ends during the weld process
