 Machubu Achitsulo a ASTM A213 Kunja Kwa Diameter ndi Kulekerera Kwamakoma a Khoma

ASTM A213 Standard Scope
1.1 Kufotokozera uku kumakwirira chitsulo chosakanizika cha ferritic ndi austenitic boiler, chotenthetsera, ndi machubu osinthanitsa kutentha, osankhidwa Magiredi T91, TP304, ndi zina zotero. Zitsulo izi zalembedwa mu Table 1 ndi 2.
1.2 Maphunziro omwe ali ndi chilembocho, H, m'matchulidwe awo, ali ndi zofunikira zosiyana ndi zamagulu ofanana omwe alibe chilembo, H. Zofunikira zosiyanazi zimapereka mphamvu zowonjezereka zophulika kuposa zomwe zimatheka m'makalasi ofanana popanda zofunikira zosiyanazi.
1.3 Makulidwe a machubu ndi makulidwe omwe nthawi zambiri amaperekedwa motere ndi 1/8 in. [3.2 mm] mkati mwake mpaka 5 mainchesi [127 mm] kunja kwake ndi 0.015 mpaka 0.500 mkati. [0.4 mpaka 12.7 mm], kuphatikiza, mu makulidwe ochepa a khoma kapena, ngati atchulidwa motsatira, makulidwe apakati a khoma.Machubu okhala ndi ma diameter ena atha kuperekedwa, malinga ngati machubu otere atsatira zofunikira zina zamtunduwu.
1.4 Miyezo yotchulidwa mu mayunitsi a SI kapena ma inchi-pounds iyenera kuwonedwa mosiyana ngati muyezo.Mkati mwamawu, mayunitsi a SI akuwonetsedwa m'mabulaketi.Miyezo yotchulidwa mu dongosolo lililonse silingakhale yofanana ndendende;Choncho, dongosolo lililonse lidzagwiritsidwa ntchito paokha.Kuphatikiza zikhalidwe kuchokera ku machitidwe awiriwa kungapangitse kuti zisagwirizane ndi muyezo.Mayunitsi a inchi-pounds adzagwiritsidwa ntchito pokhapokha ngati dzina la "M" lachidziwitsochi latchulidwa mu dongosolo.
TABLE 1 Chemical Composition Limits,% A, ya Low Alloy SteelA Maximum, pokhapokha ngati kuchuluka kapena kuchepera kumawonetsedwa.Kumene ma ellipses (...) akuwonekera patebuloli, palibe chofunikira, ndipo kusanthula kwa chinthucho sikuyenera kutsimikiziridwa kapena kufotokozedwa.

B Ndizololedwa kuyitanitsa T2 ndi T12 yokhala ndi sulfure ya 0.045 max..

C Kapenanso, m'malo mwa chiŵerengero chocheperako, zinthuzo zidzakhala ndi kuuma kochepa kwa 275 HV mu chikhalidwe chowumitsidwa, chomwe chimatanthauzidwa ngati pambuyo pa austenitizing ndi kuzizira kutentha kwa chipinda koma isanayambe kutentha.Kuyezetsa kuuma kudzachitika pakati pa makulidwe a chinthucho.Kuchuluka kwa kuyezetsa kolimba kudzakhala zitsanzo ziwiri za mankhwala pagawo lililonse la kutentha ndipo zotsatira zoyesa kuuma zidzafotokozedwa pa lipoti la mayeso.
