A516 Qib 70(los yog ASME SA516 Qib 70) yog siv davsiab hlab ntsha zoo (PVQ) carbon steel phajtsim los rau nruab nrab mus rau qis- qhov kub thiab txias kev pab cuam, paub txog nws zoo heev torque toughness, ua rau nws zoo tagnrho rau welded tso tsheb hlau luam thiab boilers uas muaj kua los yog gases nyob rau hauv siab. Nws yog ib qho muaj zog, ntau yam hlau nrog kev tswj cov tshuaj lom neeg (manganese, silicon, carbon) thiab cov khoom siv kho tshuab (lub zog tensile 70-90 ksi) uas ua kom muaj kev ntseeg siab hauv kev thov.

Cov ntawv thov tseem ceeb:
Lub nkoj siab:
Kev siv ntau tshaj plaws, kom muaj cov kua dej lossis cov pa roj hauv lub siab, tshwj xeeb tshaj yog nyob rau hauv petrochemical sector. Cov hlab ntsha no tau ua haujlwm dav hauv cov chaw ua dej, cov nroj tsuag tshuaj, thiab cov chaw ua haujlwm sab nrauv, qhov chaw uas lawv yuav tsum muaj kev ntseeg siab rau sab hauv siab, kub caij tsheb kauj vab, thiab corrosive ib puag ncig. Vim nws lub zog zoo heev thiab tawv, SA 387 steel feem ntau tau teev tseg rau cov reactors, cov khoom sib cais, thiab lwm yam tseem ceeb heev - cov khoom siv.
Boilers & Kub Exchangers:
Siv rau cov khoom siv hluav taws xob uas muaj qhov kub thiab txias. Nyob rau hauv ob qho tib si pa thiab ua ke - voj voog fais fab nroj tsuag, SA 387 steel yog siv rau boiler nruas, headers, thiab kub exchanger tubesheets. Nws muaj peev xwm tswj tau cov khoom siv kho tshuab ntawm qhov kub siab ua rau nws tsim nyog rau cov tshuab tsim hluav taws xob uas ua haujlwm nyob rau hauv cov xwm txheej hnyav rau lub sijhawm ntev.
Cia Tank:
Rau qhov loj - qhov chaw cia cov kua thiab roj, feem ntau ua tau raws li API 650/620 tus qauv. SA 387 steel feem ntau yog siv rau hauv kev tsim kho cov av saum toj thiab hauv av tso tsheb hlau luam rau cov roj av, cov khoom siv roj av, thiab ntau yam tshuaj. Nws txoj kev weldability zoo thiab tsis kam ua rau cov pob txha tawg kom ntseeg tau cov qauv kev ncaj ncees ntawm cov khoom loj no - ntim ntim, txawm tias nyob rau hauv seismic thiab ib puag ncig loads.
Cov khoom siv Cryogenic:
Haum rau cov ntawv thov kub tsawg heev - xws li LNG cia vim nws cov tawv tawv. Cov ntaub ntawv muaj peev xwm khaws tau lub zog muaj zog ntawm qhov kub qis qis ua rau nws zoo tagnrho rau cov tso tsheb hlau luam cryogenic, cov kav dej, thiab cov cuab yeej ua haujlwm siv hauv LNG terminals thiab lwm yam qis -kub muaj cov nroj tsuag.
Khoom siv:
Fabrication ntawm compressors, pipelines, thiab lwm yam structural qhov chaw. SA 387 steel feem ntau xaiv rau hnyav-cov khoom siv tshuab ua haujlwm uas xav tau lub zog siab thiab ua haujlwm ntev. Nws kuj tseem siv tau rau hauv siab - cov kav xa dej siab rau kev thauj cov roj, roj, thiab lwm yam kua hauv qhov ntev.
Cov yam ntxwv ntawm tus qauv:
Nws tuaj yeem pom hauv cov choj, cov tsev, cov thawv ntim khoom, thiab kev thauj mus los (tsheb thauj khoom, tsheb ciav hlau). Hauv cov ntawv thov no, cov hlau muab kev sib xyaw ua ke zoo ntawm lub zog, toughness, thiab tus nqi -kev ua tau zoo. Nws yog siv nyob rau hauv choj girders, lub tsev thav duab, thiab ntau yam khoom siv thauj mus los uas txhim khu kev qha kev ua tau zoo nyob rau hauv dynamic thiab static loads yog qhov tseem ceeb.

516 GR 70 sib npaug li cas?
Dab tsi yog cov khoom sib npaug rau A516 GR 70? Cov sib npaug sib npaug suav nrog ASME SA516 GR 70, EN 10028 P355GH, thiab BS1501 224-490 A & B, tsim nyog rau kev siv lub nkoj zoo sib xws.
A516 GR 70 khoom qib yog dab tsi?
A516 Qib 70 yog qhov kev xaiv zoo tshaj plaws rau kev pabcuam hauv qis dua ambient kub daim ntaub ntawv nrog zoo heev torque toughness thiab zoo weldability. Cov qib steel no yog siv nyob rau hauv ob qho tib si siab hlab ntsha thiab muaj boilers thiab muaj peev xwm tiv taus siab kub sib txawv.
A516 Qib 70 piv rau SA 285 Gr.C li cas?
A516 Qib 70 muaj lub zog ntau dua thiab muaj zog dua qhov kub thiab txias dua li SA 285 Gr.C. SA 285 Gr.C yog lub zog qis dua cov pa roj carbon steel rau kev pabcuam nruab nrab, thaum A516 Qib 70 yog tsim los rau kev thov ntau dua, tshwj xeeb tshaj yog nyob rau hauv qis dua.
Dab tsi yog qhov corrosion kuj ntawm A516 Qib 70?
Nws muaj qhov nruab nrab corrosion tsis kam, feem ntau ntawm carbon steels. Nws yog tsim rau cov kev pab cuam uas tsis yog-corrosive los yog me ntsis corrosive. Nyob rau hauv ib puag ncig nruj, cov txheej txheem, cov ntaub ntawv, lossis cov khoom siv ntau dua raug pom zoo.
Thaum twg kuv yuav tsum xaiv A516 Qib 70 rau kuv qhov project?
Xaiv A516 Qib 70 thaum koj xav tau lub siab lub nkoj steel nrog lub zog zoo, zoo heev qhov kub thiab txias toughness, thiab txhim khu kev qha weldability. Nws yog qhov zoo tagnrho rau lub tank cia thiab cov hlab ntsha siab tuav cov roj liquefied, tshuaj, lossis ua haujlwm hauv huab cua txias.
