Archived Rulemaking: Transportation of Natural and Other Gas by Pipeline; Ovality of Field Bends In Steel Pipe

49-fr-43728.pdf (277.31 KB)

Part 192 limits the ovality of field bends in steel pipe more than 4 inches in diameter by specifying that the maximum outside diameter may not exceed the minimum outside diameter by more than 22 percent of the nominal diameter. This rule in § 192.313(a)(2) has been reviewed along with other pipe bending requirements and has been found to be unnecessary for safety. Therefore, MTB proposes to remove the ovality limitation requirement.
