Walton\nTechnical Director\nGray & Ductile Iron Founders\nSociety Inc.\nEast Sixty Building\nCleveland, Ohio 44114\nDear Mr. Walton:\nThis is in reply to your letter of March 24, 1971, inquiring as to the reason why particular aspects\nof ductile iron valve manufacture and use were selected for regulation.\nThe requirements of the Federal Minimum Safety Standards relating to the use of welding on\nductile iron shell components in valves, were an adoption, in regulatory language of the existing\nprovisions of the ANSI B31.8 Code, 1968 edition, and in this area did not increase the\nrequirements of the code.\nYour letter of December 18, 1970, has been viewed as a request for the initiation of rulemaking,\nand accordingly, your proposal for the amendment of the regulations concerning the manufacture\nof valves for gas transmissions, is now under active consideration. We will be happy to keep you\ninformed of any developments in this matter.\nIf we can be of further assistance, please let us know.\nSincerely,\n/signed/\nJoseph C. Caldwell\nActing Director\nOffice of Pipeline Safety\nDB\nC:\\WP51\\INTERPRT\\192\\145\\71-04-08\n1","truncated":false,"body_characters":1140}
