. Concerning. Pipe Material Supplied By Guyon Alloys (55(e).- 84-08)

- , ' Description of-the: Problem'

,The problem pertains to certain items of ASME pipe material supplied by Guyon L Alloys, Incorporated, under. Field Purchase Order No. NMP2-FP0-12345. Guyon

Alloys had ' purchased _.this: material from Sharon Tube Company, Sharon, Pennsylvania. Guyon ; informed Stone &; Webster. Engineering Corporation that

'during an . audit of- the .Sharon Tube quality program, it was discovered that <

under strict-interpretation of;ASME-Section III rules, certain items of SA&l05 EGrade 'B pipe were not actually manufactured by'Sharon Tube although so s -indicated- by. Certified Material' Test Reports pro.vided by Sharon Tube to~ Guyon .

Alloys, Incorporated. -

~ - -

iSharon Tube: furnished to Guyon Alloys certain items of hot-finished or rolled -

a ..pipecl ' inch NPSf through ~1-1/2' inch NPS which, according to Guyon Alloys; _'were .

manufactured by U.S. Steel at' Gary, _ Indiana, under its qualified NCA-3800' E <  ; quality program .to. the chemical,' finish and dimensional requirements -only of "

A-106. . Upon receipt, Sharon; Tube performed.mechinical' tests as required by :

iSA-106 '(i.e., : tensile, bend -and' hydrostatic)/trinned or faced ends and '

fapplied final coating'and markings but' did not affect the ' material

properties. Sharon- Tube

issued and supplied Certified Material Test--Reports r to; Guyon Alloys,' Incorporated which certify that the pipe was produced in

. accordance with its : qualified quality program. : These~ Certified Material Test-'

Reports incorporated the results of tha Sharon Tub'e mechanical tests"alo,ng s

.with the chemical' analysis results from U.S. Steel. Certified Material Test g 1 Reports (showing conformance to , ASTM A-106). -

'Upon;receiptiof the subje'dt matref al, Sharon Tube performed mechanical tests' s!

' Alloys, the. material. was manufactured by U.S. Steel un' der a qualified :NCA-3800

'. lof the opinion that this'is not a significant quality breakdown and that 1( "

,. fthis'problemtwere.to-have. remained 6ncorrected, it would not have adversely *
