ASTM A537 Hlau Phaj
ASTM A537 specification yog tus qauv Specification rau Pressure Vessel Phaj, Thaum tshav kub kub kho, Carbon-Manganese-Silicon Steel siv nyob rau hauv daim ntawv thov ntawm fusion welded siab hlab ntsha thiab cov qauv. Cov ntawv thov ib txwm yog cov hlab ntsha siab tsim los rau nruab nrab thiab qis-kub qhov kev pabcuam uas yuav tsum tau ua kom muaj kev sib tw zoo heev nrog rau API 650 thiab API 620 cia tso tsheb hlau luam. Cov khoom siv hauv chav kawm 1 yog muaj raws li Normalized thiab Chav Kawm 2 muaj xws li Quenched & Tempered daim hlau.
GNEE STEELtsim ASTM A537 ntawm tag nrho cov qib, ASTM A537 specification npog tus qauv rau tshav kub kho carbon manganese-silicon steel daim hlau npaj rau fusion welded siab hlab ntsha thiab cia tank. Nws yog ib hom hlau tsis tshua muaj hlau uas npog 3 qib (Class 1, Chav Kawm 2, Chav Kawm 3), steel phaj ntawm cov qib no yog siv thaum tawm los thiab tensile lub zog ntawm ASTM A516 tsis tuaj yeem ua tau raws li cov kev cai ntawm kev pabcuam siab xws li boiler thiab siab. cov hlab ntsha hauv cov roj, roj, roj av kev lag luam.
ASTM A537 class1 steel phaj daim ntawv thov yog API 650 thiab API 620 cia tso tsheb hlau luam, cov hlab ntsha siab tsim los rau nruab nrab thiab qis-kub kev pabcuam, yuav tsum tau muaj kev sib tw zoo heev. Class 1 steel yog tiav raws li Normalized thiab Class 2 yog tiav raws li Quenched & Tempered daim hlau. A537 Class 1 steel phaj qhia tau hais tias kev ua haujlwm txias txias zoo, rau kev vuam, cov khoom siv tshwj xeeb thiab cov txheej txheem vuam yuav tsum tau ua kom tsis txhob muaj teeb meem ntawm cov qauv hlau.
