ASTM A515 Qib 60 65 70 Hlau Phaj

A515 Hlau Phaj Rau Boiler

---

ASTM A515 yog siab -lub zog carbon- silicon steel specification tsim rau welded siab hlab ntsha thiab muaj boilers ua hauj lwm nyob rau hauv nruab nrab mus rau siab - kub ib puag ncig. Nws muaj cov tawv tawv zoo heev thiab tuaj hauv peb qib (60, 65, 70), feem ntau rau cov roj, roj, thiab kev lag luam petrochemical.

 

ASTM A515, zoo ib yam rau ASME SA515, yog tus qauv specification rau welded carbon steel siab nkoj daim hlau siv nyob rau hauv kub kub hauv boilers thiab lwm cov hlab ntsha. A515 / S-515 nkoj steel phaj tau muab faib ua peb qib raws li lawv lub zog tensile yam tsawg kawg nkaus: Qib 60, Qib 65, Qib 70.

ASTM A515 boiler kauj ruam daim hlau nyob rau hauv thicknesses txog li 50 hli [2 nyob rau hauv] feem ntau yog muab nyob rau hauv lub dov mob tshwj tsis yog hais tias raws li kev thov.

Kev sib piv nrog ASTM A516 Qib

Rau qhov kev xav dav dav, peb piv ASTM A515 Gr.60 nrog qib ASTM A516, uas yog tsim los rau nruab nrab thiab qis dua - cov kev pabcuam kub:

Khoom	A515 Qib 60	A516 Qib 55	A516 Qib 60	A516 Qib 65	A516 Qib 70
Kev Pabcuam Kub	Nruab nrab / Siab	Nruab nrab / qis	Nruab nrab / qis	Nruab nrab / qis	Nruab nrab / qis
Cov ntsiab lus carbon (Max%)	0.24-0.31	0.18-0.26	0.21-0.27	0.24-0.29	0.27-0.31

ASTM A516 Qib 55: Qhov zoo tshaj plaws rau qis - daim ntawv thov kub nrog cov ductility siab.

ASTM A516 Qib 60: Matches A515 Gr 60 nyob rau hauv lub zog tab sis yog optimized rau qis kub.

ASTM A516 Qib 65: Muab lub zog ntau dua, haum rau cov xwm txheej nruab nrab.

ASTM A516 Qib 70: Muab lub zog ntau dua, zoo tagnrho rau kev thov qis dua -kub siv.

Rau siab -kev siv kub, ASTM A515GR.60 ua tau zoo dua qib A516 vim nws cov qauv zoo li qub thiab txhim kho cov cua sov.

• A 515 / A 515M thiab A 516 / A 516M specifications

  Hauv kev lag luam boiler tsev, cov khoom siv feem ntau yog los ntawm ASTM A 516 / A 516M thiab A 515 / A 515M steel specifications.

  
  A515 / A515M Standard specification rau siab nkoj phaj, carbon steel, rau nruab nrab -thiab- siab dua- kub cov kev pab cuam.This specification muaj peb boiler steel qib raws li A515 qib 70, A515 qib 65 thiab A515 qib 60.

  
  A516 / A516M Standard specification rau siab nkoj daim hlau, carbon steel, rau nruab nrab thiab tsis kub kev pab cuam.This specification muaj plaub boiler steel qib raws li A516 qib 70, A516 qib 65, A516 garde 60 thiab A516 qib 55.

  
  Thaum dov cov boiler steel phaj (A516gr70/65/60/55, A515gr70/65/60), cov kev cai dav dav yuav tsum ua raws li ASTM A 20/A 20M, Ultrasonic kuaj yuav tsum ua raws li ASTM A435 / A435M, A5785 / A5.

   

  

Hauv kev lag luam Roj & Roj, ntau lub siab -kub siab cov hlab ntsha tseem raug rau hydrogen sulfide (H2S), tsim kom muaj "Sour Service" ib puag ncig. Txheem carbon steel tuaj yeem raug kev txom nyem los ntawm Hydrogen-Induced Cracking (HIC) hauv cov xwm txheej no.

 

NtawmGnee Steel, peb txuas qhov sib txawv ntawm siab -kub tsis kam thiab tiv thaiv corrosion. PebASTM A515 Qib 65daim hlau tuaj yeem tsim tshwj xeeb thiab kuaj kom tau raws liNACE MR0175 / ISO 15156qauv. Los ntawm kev tswj cov tshuaj muaj pes tsawg leeg (tsawg leej faj thiab phosphorus) thiab ua qhov kev sim HIC nruj, peb xyuas kom meej tias koj qhov kub siab - kub boilers kuj tuaj yeem tiv taus qhov chaw qaub qaub tshaj plaws.

 

Puas yog ASTM A515 Qib 65 ua tau raws li NACE MR0175 tus qauv?
Yog lawm. Txawm hais tias kev ua raws NACE tsis yog tus qauv yuav tsum muaj rau txhua daim phiaj A515,Gnee Steel's ASTM A515 Gr.65 daim hlau raug kuaj tshwj xeeb rau NACE MR0175 thiab HIC (Hydrogen-Induced Cracking).Qhov no ua kom lawv haum rau cov kev pabcuam qaub uas yuav tsum muaj - qhov kub thiab txias thiab tiv thaiv hydrogen - vim qhov kev puas tsuaj yuav tsum tau.

 

Qhov kev pab kub siab tshaj plaws rau A515 Qib 65 yog dab tsi?
ASTM A515 feem ntau yog siv hauv chav boilers thiab cov hlab ntsha siab ua haujlwm ntawm qhov kub txog li1000℃F (538 degree). Tshaj li 800℃F, qhov tshwj xeeb ASME tso cai rau kev ntxhov siab yuav tsum tau siv los suav rau qhov ntev - tus cwj pwm ntawm cov khoom siv.

 

Puas yog A515 Qib 65 weldable?
Yog, nws yog qib weldable carbon steel. Nws muaj zoo weldability siv cov txheej txheem kev lag luam. Rau cov phaj tuab, Ua ntej- cua sov thiab Post- Weld Heat Treatment (PWHT) tau pom zoo kom ua kom muaj kev ncaj ncees thiab txo cov kev ntxhov siab sab hauv.

 

Gnee Steel ua li cas thiaj li ua tau zoo ntawm A515 Qib 65 daim hlau rau cov haujlwm tseem ceeb?
Txhua lub phaj tau ua raws li kev tswj hwm nruj, suav nrog:

Tshuaj ntsuam xyuas:Xyuas kom tsis muaj impurities kom zoo dua weldability thiab NACE ua raws.

Mechanical Testing:Txheeb xyuas qhov tensile, yield, thiab elongation zog.

Kev kuaj ultrasonic (UT):Nthuav tej yam sab hauv laminations los yog tsis xws luag.

Tshwj xeeb Corrosion Testing:HIC thiab SSCC xeem rau cov haujlwm uas xav tau kev pabcuam qaub.
