304H zosapanga dzimbiri kutentha exchanger
Zambiri Zoyambira
Heat Exchangers Tubes amagwiritsidwa ntchito kusamutsa kutentha kuchokera pamalo amodzi kupita ku ena ndi kutumiza kutentha pakati pa madzi ambiri.Zosinthanazi zitha kupezeka m'mafiriji ndi m'mafakitale agalimoto komwe kuli kutentha kwambiri komanso kutentha kwambiri.Kawirikawiri, mu exchangers kutentha kutentha kumachitika podutsa madzimadzi kudzera mu machubu ofanana.zinthu zosiyanasiyana zimagwiritsidwa ntchito popanga machubuwa.Koma chitsulo chosunthika komanso chothandiza kwambiri ndi Stainless Steel chifukwa cha mawonekedwe ake abwino komanso kapangidwe kake ka mankhwala.
Chitsulo chosapanga dzimbiri chimakhala ndi kachulukidwe kakang'ono ka chromium kamene kakawonjezera mphamvu yachitsuloyo imachulukanso.Kukhalapo kwa molybdenum muzitsulo kumawonjezera mphamvu zake ndi zina.304H ndi kalasi yapamwamba ya carbon Stainless Steel yomwe ili yabwino kuposa magiredi ena aliwonse a SS chifukwa cha katundu wake komanso kulolerana ndi malo ambiri.Gulu la 304H limapereka mphamvu zolimba kwambiri, zokwawa zazifupi komanso mawonekedwe abwino kwambiri oletsa kutentha.Ichinso ndi chifukwa chotengera kalasi iyi popanga machubu osinthanitsa kutentha.
Polankhula za mawonekedwe ake, SS 304H imapereka kukana kwabwino kwa dzimbiri, kukana kukana kwa chloride, kukana kukana kwa corrosion, kukana kuwononga kwapang'onopang'ono komanso kukana kwa dzimbiri pakutentha kwambiri komanso kupanikizika.
