ASTM A192 (ASME SA192) tuubo bir ah waa tuubo bir ah oo kaarboon ah oo aan kala go 'lahayn oo loo isticmaalo jawi heerkul sare iyo cadaadis sare leh, waxaana si weyn loogu isticmaalaa kuleyliyeyaasha iyo beddelayaasha kulaylka.
Dhexroorka dibadda: 1/2″ – 7″ (12.7 mm – 177.8 mm);
Dhumucda derbiga: 0.085″ – 1.000″ (2.2 mm – 25.4 mm);
Cabbirrada kale ee tuubooyinka birta ah ayaa sidoo kale la bixin karaa marka loo baahdo, iyadoo la raacayo dhammaan shuruudaha kale ee A192.
ASTM A192 waxaa lagu soo saaraa hab aan kala go 'lahayn waxaana loo dhammeeyaa si kulul ama qabow marka loo baahdo;
Sidoo kale, aqoonsiga tuubada birta ah waa inuu muujiyaa in tuubada birta ah ay kulul tahay ama qabow tahay.
Dhammaystirka kulul: Waxaa loola jeedaa habka loo dhammeeyo cabbirrada ugu dambeeya ee tuubada birta ah xaalad kulul. Ka dib marka tuubada birta ahi ay marto hab kulul oo wax lagu farsameeyo sida duubista kulul ama sawirista kulul, ma aha mid qabow oo sii socda. Tuubooyinka birta ah ee kulul ee la dhammeeyay waxay leeyihiin adkeysi iyo dabacsanaan wanaagsan laakiin waxay leeyihiin dulqaad cabbir weyn.
Qabow dhammeeyayTuubada birta ah waxaa loo farsameeyaa cabbirkeeda ugu dambeeya iyadoo la adeegsanayo hababka shaqada qabow sida duubista qabow ama sawirista qabow heerkulka qolka. Tuubooyinka birta ah ee qabowga lagu dhammeeyay waxay leeyihiin dulqaad cabbir oo sax ah iyo dusha sare oo siman laakiin waxay u adkeysan karaan xoogaa adkeysi ah.
Tuubooyinka birta ah ee aan kala go 'lahayn ee kulul ee la dhammeeyay uma baahna daaweyn kuleyl.
Tuubooyinka birta ah ee aan lahayn cilladaha qabow waxaa lagu daaweeyaa heerkul dhan 1200°F [650°C] ama ka sareeya ka dib marka la daweeyo qabowga ugu dambeeya.

Haddii aan si kale loogu qeexin ASTM A192, agabka lagu diyaariyey qeexitaankan waa inuu waafaqsanaadaa shuruudaha khuseeyaASTM A450/A450M.
Adkeysiga Rockwell: 77HRBW.
Tuubooyinka birta ah ee dhumucdoodu ka yar tahay 0.2" [5.1 mm].
Adkaanshaha Brinell: 137HBW.
Dhumucda derbiga ee tuubada birta ah ee 0.2" [5.1 mm] ama ka badan.
Shuruudaha hawlgalka gaarka ah, fiiri ASTM A450, Shayga 23.
· Soo noqnoqoshada: Tuubo bir ah kasta waxaa lagu sameeyaa tijaabo cadaadis hydrostatic ah.
· Waqtiga: Cadaadiska ugu yar ku hay ugu yaraan 5 ilbiriqsi.
· Qiimaha cadaadiska biyaha: Waxaa lagu xisaabiyay qaacidada soo socota. Fiiro gaar ah u yeelo cutubka.
Inji - Pound Halbeegyada: P = 32000 t/D
Cutubyada SI: P = 220.6t/D
P = cadaadiska tijaabada hydrostatic, psi ama MPa;
t = dhumucda derbiga la cayimay, gudaha ama mm;
D = dhexroorka dibadda ee la cayimay, gudaha ama mm.
· Natiijo: Haddii aysan jirin wax daadasho ah oo ku timid tuubooyinka, baaritaanka waxaa loo arkaa inuu dhaafay.
Beddelka tijaabada hydrostatic-ka ayaa sidoo kale suurtagal ah iyadoo la adeegsanayo tijaabo ku habboon oo aan burburin.
Si kastaba ha ahaatee, heerku ma qeexayo habka tijaabada aan burburin karin ee la isticmaali karo.
Tuubooyinka marka la geliyo kuleyliyaha waa inay istaagaan iyagoo fidsan oo aan lahayn dildilaac ama cillado. Tuubooyinka kululeeyaha marka si habboon loo maareeyo waa inay istaagaan dhammaan hawlaha farsamaynta, alxanka, iyo foorarsiga ee lagama maarmaanka u ah codsiga iyada oo aan la yeelan cillado.
