The Department of Transportation is considering several amendments to Part 192 to provide greater flexibility in qualifying pipe. An amendment to § 192.55 would permit the use of steel pipe manufactured before November 12, 1970, in compliance with an unlisted edition of a specification included in section I of Appendix B. An amendment to § 192.65 would permit the use of certain pipe transported by railroad before November 12, 1970, not in accordance with API RP5LI. Finally, amendments to Appendices A and B would add the 1971 editions to the lists of API pipe specifications.
