Walton\nTechnical Director\nGray & Ductile Iron Founders' Society, Inc.\nNational City - East Sixth Building\nCleveland, Ohio 44114\nDear Mr. Walton:\nThis is in reply to your letter of November 9, 1970, requesting an interpretation of 49 CFR,\nSection 192.145. Specifically, you requested information as to whether, under the regulation,\nwelding is permitted on ductile iron components in the manufacturing process when closely\ncontrolled metallurgical procedures are employed.\nIn answer to a similar request for interpretation we have replied as follows:\n\"Section 192.145 (c)(2) is taken directly from the B31.8, 1968, paragraph 831.11(b) and\nprohibits such welding.\"\nWe hope this answers your question. If you have further questions feel free to ask.\nSincerely,\n/signed/\nJoseph C. Caldwell\nDirector, Acting\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\145\\70-12-09\n1","truncated":false,"body_characters":896}
