L Finned Tube ASTM A179
ASTM A179 specification npog seamless txias-draw me me steel tshav kub exchanger thiab condenser hlab. Cov raj no yog tsim los siv rau ntau yam kev siv, xws li chav boilers, kub exchangers, thiab condensers.
Vim tias cov raj no tau tsim los ntawm cov hlau me me, lawv tsim nyog rau cov xwm txheej uas tsis muaj kev tiv thaiv corrosion tsis yog qhov tseem ceeb. Cov raj no yog txias kos, uas txhais tau hais tias lawv yog tsim los ntawm kos ib lub raj hollow los ntawm kev tuag ntawm chav tsev kub uas tsis muaj cua sov. ASTM A179 raj los ntawm ntau qhov ntau thiab tsawg thiab tuab, thiab nws tuaj yeem tsim kho kom ua tiav cov kev xav tau tshwj xeeb. Lawv feem ntau xa tawm annealed, uas txhais tau hais tias lawv yog mos thiab malleable thiab yog li yooj yim rau kev nrog. Cov raj no feem ntau pom muaj nyob rau hauv kev tsim hluav taws xob, tshuaj lom neeg, thiab petrochemical sectors. Lawv yog cov zoo meej rau kev siv nyob rau hauv tshav kub exchangers thiab condensers vim lawv zoo thermal conductivity thiab muaj peev xwm mus rau siab kub siab thiab kub.
