I. Ni ibihe bikoreshoAPI5L
1. Ibyuma by'imiyoboro ya API5L-B, bingana na Wuyang Iron na Steel ya L245, L245 ni iby'uruhererekane rw'ibirungo bike, igiciro kiri hejuru ugereranyije, igiciro cy'ibikoresho bitandukanye ntabwo ari kimwe, ahanini bikoreshwa ku miyoboro ya peteroli, imiyoboro karemano, nibindi, ni umuyoboro w'amazi urimo umuvuduko muto, imikorere yawo n'umuyoboro udafite umuvuduko wa 20# hafi ya wose.
2. Ibikoresho niIcyiciro cya X52 umuyoboro w'icyuma urimo imiyoboroIbyuma by'icyuma, ari byo bwoko bw'icyuma gifite ibisabwa byihariye bikoreshwa mu gutwara imiyoboro ya peteroli na gaze karemano. Dukurikije ubunini n'imiterere yabyo, bishobora gukorwa hakoreshejwe uruganda rushyushye rukomeza gukurura, uruganda ruzunguruka mu itanura cyangwa uruganda rufite ubunini buciriritse hanyuma bigakorwamo umuyoboro munini w'icyuma hakoreshejwe gusudira ku buryo buzunguruka cyangwa gusudira ku buryo bugororotse bwa UOE.
3. Umuyoboro w'icyuma udafite umushono cyangwa ushongeshejwe, ibisanzwe niAPI 5L (umuyoboro w'imiyoboro) PSL2ni kimwe mu byiciro, ikindi ni PSL1 ugereranije, ibisabwa na PSL2 biri hejuru ya PSL1API 5L ni ibipimo by'imiyoboro y'amazi byakozwe n'Ikigo cy'Abanyamerika gishinzwe Peteroli, B ni kimwe mu byiciro by'icyuma cy'imiyoboro.
II. Igipimo ngenderwaho cya API5L
1. API5L isanzwe, umubare w'imiyoboro y'icyuma n'umuyoboro WLD 10" SCH STD API5L ASTM A106 GRB ifite icyuma kidakora neza mu gice kimwe ntugomba kurenza 50% by'umubare w'imiyoboro. Mbere yo kuyishyiraho, ikiraro cy'imiyoboro kigomba gusukura no gusukura imyobo y'imyobo cyangwa umwuka ushyushye kugira ngo ukureho umwanda uri mu myobo. Menya neza ko umwobo (umwobo ntugomba kuba munsi ya cm 127) wujuje ibisabwa kandi ukirinda kuziba imyobo.
2. Cr:≤025 Nickel Ni:≤030 Umuringa Cu:≤025 Imiterere ya mekanike: Ingufu zo gukurura za sigma b (MPa) : 560 (57) cyangwa imbaraga zo gutanga umusaruro mwinshi sigma s (MPa) : 335 (34) cyangwa delta yo kurekura (%) : kugabanya ubuso bwa bits 18 (%) : Ingufu 45 cyangwa hejuru Akv (J) : Ingufu 55 cyangwa hejuru z'imbaraga zo gukomerera za alpha kv (J/cm2).
3. API 5L igena ibyo icyuma gikoreshwa mu gukora, cyane cyane ku mbaraga zo gukurura, imbaraga zo gukuraho, ubushyuhe bw'icyumba, uburebure bw'igihe cyo gucika, nibindi. Dukurikije ubwoko bw'icyuma gikoreshwa mu gukora, API 5L igabanyijemo imiyoboro rusange y'icyuma n'imiyoboro yihariye y'icyuma, muri yo imiyoboro rusange y'icyuma igabanyijemo imiyoboro isanzwe y'icyuma n'imiyoboro ikomeye cyane y'icyuma, API 5L igena kandi ibyo icyuma gikoreshwa mu gukora mu gukora mu gukora mu byuma bikoreshwa mu gukora mu gukora mu byuma bikoreshwa mu gukora mu gukora mu byuma bikoreshwa mu gukora mu gukora mu byuma bikoreshwa mu gukora mu gukora mu byuma bikoreshwa mu gukora mu gukora mu byuma bikoreshwa mu gukora mu buryo burambye.
III, ibikoresho bya API5Lgrb ni ibihe?
1. API 5LGRB nta kibazo ifite cyangwaumuyoboro w'icyuma ushongeshejwe, igipimo ngenderwaho ni API 5L (umuyoboro w'ibikomoka kuri peteroli), PSL2 ni imwe mu nzego, urundi rwego ni PSL1 ugereranije, ibisabwa na PSL2 biri hejuru ya PSL1API 5L ni ibipimo by'umuyoboro w'ibikomoka kuri peteroli byakozwe n'Ikigo cy'Abanyamerika gishinzwe ibikomoka kuri peteroli, B ni ubwoko bw'icyuma gikoreshwa mu miyoboro.
2. ASME SA517, ASTM A517 Igikoresho cy'umuvuduko cyazimye kandi gishyushye. Ibyuma bikoreshwa mu byuma bifite imbaraga nyinshi bya ASME SA517/SA517M bikubiyemo: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrF, SA517GrE, SA517GrQ; Ibyuma bikoreshwa mu byuma bya ASTM A517/A517M bikubiyemo: A517GrA,.
3. IbikoreshoAPI 5L PSL2gisanzweumuyoboro w'icyuma uzungurukaGrB-X70 Umurambararo wo hanze 219-3650 mm Muraho, tumaze imyaka 24 dukora imiyoboro izunguruka, twizeye ko tuzagira amahirwe yo gukorana namwe.
