Ububanzi obujwayelekile be-ASTM A213
1.1 Lokhu kucaciswa kuhlanganisa ubhayela wensimbi ongenamthungo ne-austenitic, i-superheater, namashubhu okushintsha ukushisa, aqokiwe Amabanga T91, TP304, njll. Lezi zinsimbi zifakwe kuhlu kuThebula 1 no-2.
1.2 Amabanga aqukethe uhlamvu H, ekuqokweni kwawo, anezidingo ezihlukile kulawo amabanga afanayo anganalo uhlamvu H. Lezi zidingo ezihlukene zinikeza amandla aphezulu okuqhekeka kunalawo ngokuvamile angafinyelelwa emabangeni afanayo ngaphandle kwalezi zidingo ezihlukene.
1.3 Osayizi bamashubhu nobukhulu obuvame ukunikezwa kulokhu kucaciswa buyi-1/8 in. [3.2 mm] ngobubanzi bangaphakathi ukuya kuma-intshi angu-5. [127 mm] ububanzi obungaphandle kanye no-0.015 kuya ku-0.500 in. [0.4 kuya ku-12.7 mm], kuhlanganisa, ngobukhulu obuncane bodonga noma, uma kushiwo ngokulandelana, ukujiya kodonga olumaphakathi.Amashubhu anamanye amadayamitha angase anikezwe, inqobo nje uma lawo mashubhu ehambisana nazo zonke ezinye izimfuneko zalokhu kucaciswa.
1.4 Amanani ashiwo kumayunithi e-SI noma amayunithi ayintshi yephawundi kufanele abhekwe ngokwehlukana njengajwayelekile.Ngaphakathi kombhalo, amayunithi e-SI akhonjiswa kubakaki.Amanani ashiwo ohlelweni ngalunye angeke alingane ncamashi;ngakho-ke, uhlelo ngalunye luzosetshenziswa ngaphandle kolunye.Ukuhlanganisa amanani asuka kumasistimu womabili kungase kubangele ukungahambisani nezinga.Amayunithi ayintshi yephawundi azosebenza ngaphandle uma igama elithi “M” lalokhu kushiwo lishiwo ku-oda.
ITHEBULA 1 Imikhawulo Yokwakheka Kwamakhemikhali, %A, Yensimbi Ephansi Yengxubevange A Maximum, ngaphandle uma ububanzi noma ubuncane bubonisiwe.Lapho ama-ellipses (...) evela kuleli thebula, asikho isidingo, futhi ukuhlaziywa kwe-elementi akudingeki kunqunywe noma kubikwe.
B Kuvumelekile uku-oda i-T2 ne-T12 enesulfure yokuqukethwe okungu-0.045 max..
C Okunye, esikhundleni salobu buncane besilinganiso, impahla izoba nobulukhuni obuncane obungu-275 HV esimweni esiqinile, esichazwe njengokuthi ngemva kokupholisa kanye nokupholisa ekamelweni kodwa ngaphambi kokufudumeza.Ukuhlolwa kokuqina kufanele kwenziwe maphakathi nobukhulu bomkhiqizo.Imvamisa yokuhlolwa kokuqina kuzoba amasampula amabili omkhiqizo endaweni ngayinye yokwelashwa kokushisa futhi imiphumela yokuhlolwa kokuqina izobikwa embikweni wokuhlolwa kwezinto.
