Miter bend are not standard pipe fittings they are fabricated from pipes. Usually, they are preferred for size 10” & above because large size elbow is expensive. Use of miter bend is restricted to the low-pressure water line. Miter bend can be fabricated in 2, 3, & 5 pieces. Miter bend is a bend is made by cutting pipe ends at an angle and joining the pipe ends. A true miter bend is a 90 degree bend made by cutting two pipes at 45 degrees and joining them by welding. Similarly three pipes cut at 22.5 degrees will give a 90 degree miter bend.
