Kormeeraha Tuubada ASTM A106/ASME SA106
ASTM A106/ASME SA106 waa qeexidda caadiga ah ee tuubooyinka birta kaarboonka ee aan kala go 'lahayn ee loo adeegsado adeegyada heerkulka sare. Waxay ka kooban tahay saddex darajo A, B iyo C, heerka isticmaalka caadiga ahna waa A106 Heerka B. Waxaa loo isticmaalaa warshado kala duwan oo aan ahayn oo keliya nidaamyada dhuumaha sida saliidda iyo gaaska, biyaha, gudbinta macdanta, laakiin sidoo kale kuleyliyaha, dhismaha, iyo ujeeddooyinka dhismaha.

Dhimis kasta oo ah 0.01% curiyaha kaarboonka ugu badan, koror dhan 0.06% manganese oo ka sarreeya qiimaha la cayimay waa in la oggolaadaa, iyo ilaa ugu badnaan 1.35%.
Curiyayaasha Cr, Cu, Mo, Ni, iyo V ee la isku daray waa inaysan dhaafin 1%.
Xoogga iyo Xoogga Tamarta ee ASTM A106 Heerka B
Qaacidada dheereynta:
2 inji [50mm], waxaa lagu xisaabin doonaa: e = 625 000 A^0.2 / U^0.9
Halbeegyada inji-pound, e = 1940 A^0.2 / U^0.9
Faahfaahinta e, A, iyo U, fadlan halkan ka hel. (Isleeggu waa isku mid ASTM A53, tuubada API 5L.)
Xoogga Garaacista, ugu yaraan, psi [MPa] Darajada A 48,000 [330], Darajada B 60,000 [415], Darajada C 70,000 [485]
Xoogga Wax Soo Saarka ugu yar ee psi [MPa] Darajada A 30,000 [205], B 35,000 [240], C 40,000 [275]
Kordhinta 2 inji (50mm), boqolkiiba ugu yar %
Dhammaan cabbirrada yaryar ee lagu tijaabiyay qaybta oo dhan, imtixaanada safarka isdhaafka ah ee ugu yar ee dheeraynta aasaasiga ah: Darajada A Longitudinal 35, Transverse 25; B 30, 16.5; C 30, 16.5;
Haddii la isticmaalo muunadda tijaabada dhererka wareega 2 inji ee caadiga ah, qiimayaasha kor ku xusan waa: Darajada A 28, 20; B 22, 12; C 20, 12.
Jadwalka Cabbirka Tuubada ASTM A106 Heerka B
Heerkani wuxuu daboolayaa cabbirrada tuubooyinka ee NPS (National Standard Toosan) laga bilaabo 1/8 inji ilaa 48 inji (10.3mm DN6 – 1219mm DN1200), dhanka kale wuxuu waafaqsan yahay dhumucda derbiga magacaaban ee ASME B 36.10M ee caadiga ah. Cabbirrada kale ee ka baxsan ASME B 36.10M waxaa sidoo kale loo oggol yahay inay isticmaalaan qeexitaankan caadiga ah.
Alaabta ceeriin
Agabka loo isticmaalo qeexidda heerka ASTM A106 waa in lagu dabaqo foorarsiga, kala-goynta, ama hababka la midka ah ee sameynta. Haddii walxaha birta ah la alxamayo, habka alxamadu wuxuu u maleynayaa inuu ku habboon yahay heerkan ASTM A106, wuxuuna khuseeyaa jawiga shaqada ee heerkulka sare leh.
Haddii ay jirto heer sare ama heer sare oo loogu talagalay tuubooyinka birta ah ee ASTM A106, heerku wuxuu leeyahay qeexitaan ikhtiyaari ah oo loogu talagalay shuruudaha dheeraadka ah, tuubooyinka isticmaalay heerkan. Intaa waxaa dheer, qeexitaannada dheeraadka ah waxay weydiisteen tijaabada dheeraadka ah, marka dalabka la dhigayo.
