A179 khoom yog dab tsi?
ASTM A179: A179 yog aqis- qib carbon steel tshwj xeeb tsim los rau cov cua kub exchanger thiab condenser raj. Nws muaj cov thermal conductivity zoo heev thiab tsim nyog rau ob qho tib si seamless thiab welded daim ntaub ntawv.
ASTM A179 specification yog dab tsi?
ASTM A179 (SA 179) tus qauv specificationnpog seamless txias drawn low -carbon steel yeeb nkab, rau tubular heat exchanger, condensers, thiab lwm yam zoo xws li cov khoom siv hluav taws xob hloov. ASTM A179 raj npog OD ntawm 1/8 "mus rau 3", uas yog 3.2mm txog 76.2 hli.
Dab tsi yog qhov txawv ntawm ASTM A106 thiab A179?
A179 yog cov pa roj carbon tsawg uas siv rau cov khoom siv hluav taws xob sib hloov thiab cov condensers, thaum A106 yog seamless carbon steel raj uas siv rau siab - kev pabcuam kub.
Cov tshuaj muaj pes tsawg leeg ntawm A179 yog dab tsi?
ASTM A179 Tsawg Kub Carbon Steel Tube
Cov tshuaj muaj pes tsawg leeg muaj carbon, manganese, phosphorus, thiab sulfur. Kev sim yuav tsum tau: xeem hardness, flattening test, flaring test, flange test, thiab hydrostatic test.
Lub hardness ntawm A179 yog dab tsi?
ASTM A179 raj yuav tsum muaj tus lej hardnesstsis tshaj 72 HRB.
Dab tsi yog cov khoom siv SA 179?
SA179 raj yog ua los ntawmcarbon hlaunrog cov ntsiab lus tsis tshua muaj carbon, muab cov cua sov hloov pauv zoo, siab corrosion kuj, thiab kav ntev. Lawv tau dav siv hauv condensers, heat exchangers, thiab lwm yam kev siv siab -siab.
Qhov txawv ntawm ASTM a214 thiab A179 yog dab tsi?
SA-214 thiab SA-179 yog ob qho tib si carbon steel yeeb nkab qauv rau cov cua kub exchangers thiab condensers. Qhov sib txawv tseem ceeb yog cov txheej txheem tsim khoom sib txawv.SA-214 siv cov txheej txheem ERW, thaum SA-179 siv cov txheej txheem kos duab txias seamless.
