Jumlo Shiinees ah AISI 1020 P235gh DIN 2448 St 35.8 Dhuumaha Birta Kaarboonka ee aan Xumaan lahayn
Sharaxaad Gaaban:
ASTM A53 waa bir kaarboon ah oo loo isticmaalo sidii bir dhismeed ama tuubooyinka cadaadiska hooseeya.
ASTM A53 Standard waa heerka ugu caansan ee tuubooyinka birta kaarboon, inta badan waxaa loola jeedaa jajabka cufka kaarboonku wuxuu ka yar yahay 2.11% iyada oo aan ku jirin walxaha birta si ula kac ah loogu daray, iyadoo heerka kaarboonka ku jira birta uu ka mid yahay Waxyaabaha ugu muhiimsan ee saameyn ku leh xoogga birta, adkaanta ayaa kordheysa, waxayna yareysaa ductility, adkaanta iyo awoodda alxanka.Ka sokow, guud ahaan waxa kale oo ku jira xaddi yar oo silikon, manganese, baaruud, fosfooraska marka lagu daro kaarboon.Marka la barbardhigo noocyada kale ee birta, waa kan ugu horreeya, qiimaha jaban, waxqabadka ballaaran, qadarka ugu badan.Ku habboon cadaadiska magaca PN ≤ 32.0MPa, heerkulka -30-425 ℃ biyaha, uumiga, hawada, hydrogen, ammonia, nitrogen iyo batroolka, iyo warbaahinta kale.Dhuumaha birta kaarboon waa kan ugu horreeya ee loo isticmaalo cadadka ugu badan ee alaabta aasaasiga ah ee warshadaha casriga ah.Waddamada warshadaha adduunka, dadaallada lagu kordhinayo xoogga sare ee birta aluminiumka hooseeya iyo wax soo saarka birta daawaha, taas oo sidoo kale aad diiradda u saareysa hagaajinta tayada iyo ballaarinta noocyada kala duwan iyo isticmaalka.Qaybta wax soo saarka ee wadarta guud ee birta ee wadamada, qiyaastii lagu hayo ilaa 80%, ma aha oo kaliya in si weyn loo isticmaalo dhismayaasha, buundooyinka, tareenada, baabuurta, maraakiibta iyo dhammaan noocyada warshadaha wax soo saarka mishiinka, laakiin sidoo kale in petrochemical casriga ah. warshadaha, horumarinta badda, ayaa sidoo kale si weyn loo isticmaalay.
Waxaan hadda leenahay xubno badan oo shaqaale fantastic macaamiisha sare at advertising, QC, iyo la shaqaynta noocyo kala duwan oo dhibaato dhibaato gudaha nidaamka jiilka jumlo Chinese AISI 1020 P235gh DIN 2448 St 35.8 Dhuumaha Carbon Steel Pipe, Waxaan si kal iyo laab ah u soo dhaweyn doonaa dhammaan wax iibsada ka warshadaha ah. laba dal iyo dibadba si ay gacmaha is qabsadaan, una soo saaraan mustaqbal ifaya oo la arki karo si wadajir ah.
Waxaan hadda haysanaa shaqaale badan oo cajiib ah oo macaamiisha ah oo ka sarreeya xayeysiiska, QC, iyo la shaqeynta noocyo kala duwan oo dhibaato leh oo ka dhex jira nidaamka jiilkaShiinaha DIN 2448 St 35.8 Dhuumaha Birta Kaarboonka ee aan Xumaan lahayn iyo P235gh Dhuumaha Birta, Waxaan had iyo jeer ku adkaysanayaa mabda'a ah "Tayada iyo adeeggu waa nolosha alaabta".Ilaa hadda, xalalkayaga waxaa loo dhoofiyay in ka badan 20 waddan oo hoos yimaada xakamaynta tayada adag iyo adeegga heerka sare.

ASTM A53 waa daawaha kaarboonka, kaas oo loo isticmaali karo sidii bir dhismeed ama dhuumaha cadaadiska hooseeya.
ASTM A53 (ASME SA53) tuubada birta kaarboon waa qeexid daboolaysa birta galvanized aan lahayn iyo alxanka leh ee NPS 1/8 "ilaa NPS 26. 53 waxaa loogu talagalay cadaadiska iyo codsiyada farsamada waxaana sidoo kale la aqbali karaa kuwa caadiga ah loo isticmaalo uumiga, biyaha, gaaska, iyo khadadka hawada.
Dhuumaha A53 waxay u kala baxaan saddex nooc (F, E, S) iyo laba darajo (A, B).
Nooca A53 F waxaa lagu soo saaray alxanka foornada ama waxaa laga yaabaa inuu leeyahay alxan joogto ah (Fasalka A kaliya)
Nooca A53 wuxuu leeyahay alxanka caabbinta koronto (Fasalada A iyo B)
Nooca A53 waa tuubo aan waxba tarayn waxaana laga helaa fasalada A iyo B)
A53 Fasalka B bilaa-xun waa badeecadeena ugu badneyd ee hoos timaadda qeexitaankan iyo tubbada A53 ayaa caadi ahaan laba-shahaadad u leh A106 B tuubo aan cillad lahayn.
ASTM A53 tuubooyin bir ah oo aan kala go 'lahayn waa sumad Maraykan ah.A53-F waxay u dhigantaa walxaha Q235 ee Shiinaha, A53-A waxay u dhigantaa Shiinaha No. 10, iyo A53-B waxay u dhigantaa Shiinaha No. 20.
