I-ASTM A213 uMda oMgangatho
1.1 Le nkcazo igubungela ibhoyila ye-ferritic engenamthungo kunye ne-austenitic steel, i-superheater, kunye ne-heat-exchanger tubes, ekhethiweyo yamaBakala T91, i-TP304, njl. Ezi ntsimbi zidweliswe kwiiThebhile 1 kunye no-2.
1.2 Amabanga anoleta, H, ekutyunjweni kwawo, aneemfuno ezahlukileyo kulawo akumabanga afanayo angenalo unobumba, H. Ezi mfuno zahlukeneyo zinika amandla aphezulu okuqhekeza kunoko kufumaneka ngokuqhelekileyo kumabakala afanayo ngaphandle kwezi mfuno zahlukeneyo.
1.3 Ubukhulu betyhubhu kunye nobukhulu obudla ngokunikezelwa kolu balulo yi-1/8 ngaphakathi. [3.2 mm] ngaphakathi kwedayamitha ukuya kwi-5 ngaphakathi. kubunzima obuncinane bodonga okanye, ukuba luchazwe ngokomyalelo, ubukhulu bodonga oluphakathi.Iityhubhu ezinobunye iidayamitha zinokufakwa, ngaphandle kokuba iityhubhu ezinjalo zithobelana nazo zonke ezinye iimfuno zolu nkcukacha.
1.4 Amaxabiso axeliweyo nokuba ziiyunithi ze-SI okanye iiyunithi ze-inch-pound kufuneka zithathwe ngokwahlukeneyo njengomgangatho.Ngaphakathi kokubhaliweyo, iiyunithi ze-SI ziboniswa kwizibiyeli.Amaxabiso achazwe kwinkqubo nganye asenokungalingani ncam;ke ngoko, inkqubo nganye iya kusetyenziswa ngokuzimeleyo kwenye.Ukudibanisa amaxabiso kwiinkqubo ezimbini kunokubangela ukungahambelani nomgangatho.Iiyunithi ze-intshi yephawundi ziya kusebenza ngaphandle kokuba igama elithi “M” le nkcazelo lichaziwe kulandelelwano.
ULUHLU 1 IMida yoBume beMichiza, i-% A, yeNsimbi ye-Alloy ePhantsi, ngaphandle kokuba uluhlu okanye ubuncinane bubonisiwe.Apho iiellipses (...) zivela kule theyibhile, akukho mfuneko, kwaye uhlalutyo lwesiqalelo akufuneki lumiselwe okanye luxelwe.
B Kuvumelekile uku-odola i-T2 kunye ne-T12 kunye nomxholo wesulfure we-0.045 max..
C Kungenjalo, endaweni yalomlinganiselo ubuncinane, imathiriyeli iya kuba nobulukhuni obuncinci be-275 HV kwimeko yokuqina, echazwe emva kokupholisa kunye nokupholisa kwiqondo lobushushu begumbi kodwa ngaphambi kokufudumeza.Uvavanyo lokuqina luya kwenziwa phakathi kobungqingqwa bemveliso.Ubunzima bovavanyo oluphindaphindiweyo luya kuba ziisampuli ezimbini zemveliso kwiqashiso lonyango lobushushu kwaye iziphumo zovavanyo lobulukhuni ziya kuxelwa kwingxelo yovavanyo lwemathiriyeli.
Umphezulu Upeyintiwe omnyama, ipeyintiwe ngepeyinti yepeyinti
