Notes:

  1. All dimensions are given in Inches.
  2. Welding shall be in accordance with the job specifications.
  3. These Miter elbows are to be used when authorized by the piping spec's.
  4. Use "A" dimension only where necessary to meet close clearance requirements or when connecting to flange or fitting.
  5. Material shall be as specified in the job piping materials specification class.
  6. "M" dimension does not include taper bore length.
  7. The "M" dimension must be calculated for Miter elbows other than 78", 54", 48" and 42".
