ASTM A213 T12(ASME SA213 T12) waa tuubo bir ah oo aan lahayn daawaha oo loogu talagalay adeegga heerkulka sare.
Walxaha ugu muhiimsan ee isku-darka ah waa 0.80–1.25% chromium iyo 0.44–0.65% molybdenum, kuwaas oo u kala saara bir isku-darka chromium-molybdenum. Waxaa si weyn loogu isticmaalaa deegaannada heerkulka sare iyo cadaadiska sare sida kuleyliyeyaasha, kuleyliyeyaasha sare, iyo beddelayaasha kulaylka.
Tuubada T12 waxay leedahay xoog jiidis ugu yaraan ah 415 MPa iyo xoog wax soo saar ugu yaraan ah 220 MPa.
Magaca UNS ee darajadan waa K11562.

Soo-saaraha iyo Xaaladda
Tuubooyinka birta ah ee ASTM A213 T12 waa in lagu sameeyaa habka aan kala go 'lahayn waana in lagu sameeyaa mid kulul ama mid qabow, sida ku cad.
Daaweynta Kulaylka
Dhammaan tuubooyinka birta ah ee T12 waa in lagu daaweeyaa kulaylka.
Hababka daaweynta kulaylka ee la oggol yahay waxaa ka mid ah fdaminta kulaylka ama kuleyliyaha isothermal, caadiyeynta iyo hagaajinta, amabaabi'inta cadaadiska hoose.

Tuubo kasta waa in lagu sameeyaa tijaabada korontada ee aan burburin ama tijaabada hydrostatic-ka.Nooca tijaabada la isticmaalayo waa inuu ahaadaa ikhtiyaarka soo saaraha, haddii aan si kale loogu qeexin dalabka iibsiga.
Hababka tijaabada waa in loo sameeyaa si waafaqsan shuruudaha khuseeya ee Qaybaha 25 iyo 26 ee ASTM A1016.
Cabbirrada tuubooyinka ASTM A213 T12 iyo dhumucda derbiga waxaa badanaa lagu qalabeeyaa dhexroor gudaha ah oo u dhexeeya 3.2 mm ilaa dhexroorka dibadda ee 127 mm, iyo dhumucda derbiga ugu yar laga bilaabo 0.4 mm ilaa 12.7 mm.
Cabbirrada kale ee tuubooyinka birta ah ee T12 ayaa sidoo kale la bixin karaa, iyadoo la raacayo dhammaan shuruudaha kale ee ASTM A213.
Tuubooyinka birta ah ee aan lahayn tolmada ASTM A213 T12 waxaa ugu horreyn loo isticmaalaa jawi adeeg heerkul sare iyo cadaadis sare leh. Codsiyada caadiga ah waxaa ka mid ah
1. Kuleyliyaha Sare iyo Kuleyliyaha Dib-u-cusboonaysiinta
Waxaa loo isticmaalaa warshadaha korontada ee tuubooyinka kuleyliyaha sare iyo kuwa dib-u-kuleyliyaha ee ka shaqeeya heerkulka sare iyo cadaadiska.
Si ballaaran ayaa loogu isticmaalaa tuubooyinka kuleyliyaha ee saldhigyada korontada ku shaqeeya, cutubyada soo kabashada kulaylka qashinka, iyo kuleyliyeyaasha warshadaha.
3. Beddelayaasha Kulaylka
Ku habboon tuubooyinka isweydaarsiga kulaylka ee warshadaha batroolka iyo kiimikada sababtoo ah iska caabin wanaagsan oo ay u leedahay socodka iyo xasilloonida kulaylka.
4. Tuubooyinka Foornada iyo Kuleyliyaha
Waxaa lagu rakibay fiilooyinka foornada warshadaha sifeynta, tuubooyinka kululeeyaha, iyo kuleyliyeyaasha habka halkaas oo looga baahan yahay iska caabbinta oksaydhka iyo xoogga muddada dheer.
5. Tuubooyinka Cadaadiska ee Warshadaha Korontada iyo Kiimikada Batroolku
Waxaa loo isticmaalaa dhuumaha heerkulka sare leh, oo ay ku jiraan khadadka uumiga iyo khadadka gaadiidka dareeraha kulul.
