If you answered yes, than you should consider wearbacks for your
elbows. For decades, Albina has supplied customers with
bent elbows where we weld a
plate or
channel to the outside of the bend (acting as the wearback). A wearback is installed to act as an additional layer to the bend, when the backside of an
elbow finally is worn through, any materials running in the piping system will remain inside and the piping system will continue to function due to the extra layer of material on the backside of the
elbow. We recently bent some 8" SCH80 T304L S/S SMLS to 30° elbows. After bending the
elbows, we bent and fabricated wearbacks out of ½” stainless
plate and welded the wearbacks to the outside of the pipe elbows.
