ASTM A515 Qib 70yog ib hom carbon steel phaj haum rau siab-cov ntawv thov kev ua haujlwm nyob rau hauv siab- qhov kub thiab txias. Nws boasts weldability zoo heev, txhim khu kev qha kev ntseeg siab, thiab tsis kam mus rau thermal qaug zog, ua rau nws nyiam xaiv nyob rau hauv cov roj thiab roj, lub zog tsim, thiab tshuaj ua sectors. Cov qib no tau siv dav los tsim cov hlab ntsha siab, boilers, cov khoom siv hluav taws xob, thiab cov tso tsheb hlau luam, vim nws tuaj yeem tiv taus cov kev pabcuam hnyav uas cuam tshuam nrog kev kub siab thiab kub hloov pauv yam tsis muaj kev cuam tshuam kev ua haujlwm.

daim ntawv thov
Roj thiab roj kev lag luam siab- cov khoom siv bearing
Nws yog cov khoom siv tseem ceeb rau kev tsim cov hlab ntsha siab siv hauv kev tshawb nrhiav hydrocarbon, kho kom zoo, thiab khaws cia, muaj peev xwm tiv taus kev ua haujlwm hnyav uas cuam tshuam nrog kev hloov pauv siab thiab corrosive media contact.
Boilers thiab kub exchangers
Dav siv nyob rau hauv kev tsim kho ntawm boilers muaj boilers thiab tshav kub exchange units rau lub hwj chim tiam, cua sov systems, thiab tshuaj ua hauj lwm, raws li nws tuav ruaj khov yam ntxwv kev ua tau zoo nyob rau hauv ntev -lub sij hawm elevated- kub thiab siab pab.
Industrial cia tanks
Siv los tsim cov tank cia rau cov kua dej siab thiab siab -kub kua, ua tau raws li kev nyab xeeb thiab kav ntev ntawm cov tshuaj, petrochemical, thiab lub zog cia sectors.
Lwm yam siab- cov khoom tseem ceeb
Txais siv los tsim cov plhaub reactor, lub taub hau siab, thiab cov khoom tseem ceeb hauv cov nroj tsuag tshuaj thiab metallurgical cov chaw, qhov uas tiv taus thermal qaug zog thiab siab -cov kabmob muaj peev xwm yog qhov tseem ceeb.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau kev tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
Qhov txawv ntawm A515 qib 70 thiab A 516 70 yog dab tsi?
SA-516-70 feem ntau yog siv rau cov hlab ntsha siab uas yuav tsum tau ua haujlwm nruab nrab thiab qis dua. SA515 GR 70 yog siv rau nruab nrab thiab siab dua cov kev pabcuam kub. ASME cov qauv: Ob qho khoom siv ua raws li cov qauv ASME tshwj xeeb rau kev siv lub nkoj siab.
Dab tsi welding pas nrig rau A515 Qib 70?
Rau ASTM A515 Qib 70 cov pa roj carbon steel, feem ntau vuam rods (electrodes/wires) muaj xws li E7018 (SMAW/Stick) rau kev siv, ER70S-6 (GMAW/MIG) rau zeb nplai, E71T-1C/12MJ (FCAW/Flux-Cored, 2) rau siab deposit welds.
