A COPY OF THE 1982 AGA PIPELINE RESEARCH SUMMARY IS ATTACHED FOR YOUR REVIEW. THE PIPELINE RESEARCH COMMITTEE ACTIVELY HAS STUDIED STRESS CORROSION CRACKING AND METHODS TO PREVENT AND CONTROL IT OVER THE PAST TEN YEARS AND CURRENTLY EXPENDS SOME $200,000 TO $300,000 OF ANNUAL RESEARCH FUNDS ON THIS SUBJECT. A BRIEF DESCRIPTION OF THESE EFFORTS CAN BE FOUND IN "REVIEW OF STATUS OF RESEARCH REGARDING PREVENTIVE MEASURES FOR STRESS CORROSION CRACKING, FRACTURE INITIA TION AND FRACTURE PROPOGATION, REVISED SEPTEMBER 1978" BY R. FESSLER AND R. EIBER (AGA CATALOG #L00034, $7.50). A DISCUSSION OF CURRENT AGA WORK ON STRESS CORROSION CRACKING CAN BE FOUND ON PAGE 7 OF THE SUMMARY. THE EFFECTS OF DENTS AND GOUGES ON LINE PIPE HAVE ALSO RECEIVED CONSIDERABLE ATTENTION BY THE AGA PIPELINE RESEARCH COMMITTEE. ON THIS SUBJECT YOU MAY WISH TO REVIEW A STUDY ENTITLED "THE EFFECTS OF DENTS ON FAILURE CHARACTERISTICS OF LINE PIPE," BY R. J. EIBER ET AL.; 1981 (AGA CATALOG #151403, $10.00).
