Young\nThe Standard Oil Company\nMidland Building\nCleveland, Ohio 44115\nDear Mr. Young:\nThis responds to your letter dated November 18, 1977, in which you\nask, \"does the term 'cracks' as stated in DOT Section 195.230 and\nSection 195.232 exclude 'shallow crater cracks or star cracks'\nwhich are of acceptable dimensions and 'not considered injurious\ndefects' according to Section [sic] 6.7 of API 1104 and DOT Section\n195.228?\" The answer is Yes, because the acceptability of a weld\nis determined according to the standards in Section 6 of the 1973\nedition of API Standard 1104.\nSection 6.7 of API 1104 states: \"Shallow crater cracks or star\ncracks which are located at the stopping point of weld beads and\nwhich are the result of weld metal contraction during\nsolidification are not considered injurious defects unless their\nlength exceeds 5/32 inch. With exception of these shallow crater\ncracks, no weld containing cracks, regardless of size or location,\nshall be acceptable.\" The Office of Pipeline Safety Operations\ninterpreted the requirement to mean that shallow crater cracks or\nstar cracks 5/32 inch or less are not significant in the assessment\nof a weld. We believe that it would be incorrect to conclude that\nthese specific cracks are identified in Section 195.230(a)(1) and\nSection 195.232(a), since they are not considered injurious\ndefects.\nWe trust that we have satisfactorily responded to your inquiry.\nSincerely,\nCesar DeLeon\nActing Director\nOffice of Pipeline\nSafety Operations\ndal\\195\\228\\78-02-10\n1\n\n<<<PAGE 2>>>\n\nNovember 18, 1977\nMr. C. DeLeon, Acting Director\nDepartment of Transportation\nOffice of Pipeline Safety Operations\n2100 - 2nd Street, Southwest\nWashington, DC 20590\nDear Mr. DeLeon:\nThis letter is a request from Standard Oil of Ohio for a ruling of\ninterpretation from your department concerning API Standard 1104,\nStandard for Welding Pipelines and Related Facilities and DOT Part\n195, Title 49, Code of Federal Regulations.\nSection 6.7 (Nondestructive Testing) of API 1104 provides limits of\nacceptability for shallow crater cracks or star cracks, and states\nthey are not considered injurious defects unless their length\nexceed 5/32 inch. DOT Section 195.228 states weld acceptability\nshall be determined according to Section 6 of API 1104, 1973\nedition. DOT Sections 195.230 and 195.232 also discuss weld cracks\nand their relationship to acceptable weld repairs.\nThe question Standard Oil proposes and requests for your formal\nwritten interpretation is this:\nDoes the term \"cracks' as stated in DOT Section 195.230 and\nSection 195.232 exclude \"shallow crater cracks or star cracks\"\nwhich are of acceptable dimensions and \"not considered\ninjurious defects\" according to Secion [sic] 6.7 of API 1104\nand DOT Section 195.228?\nYour interpretation of this question will be greatly appreciated.\nSincerely,\nRobert R.
