304H insimbi engagqwali exchanger ukushisa
Ulwazi Oluyisisekelo
Amashubhu Okushintsha Ukushisa ngokuyisisekelo asetshenziselwa ukudlulisa ukushisa ukusuka endaweni ethile emile kuya kwenye ngokudlulisa ukushisa phakathi koketshezi olungaphezu kolulodwa.Lawa ma-exchangers angatholakala eziqandisini nasezimbonini zezimoto lapho kunokushisa okuphezulu nendawo yokushisa.Ngokuvamile, kuma-exchangers ukudlulisa ukushisa kwenzeka ngokudlulisa uketshezi ngamashubhu ahambisanayo.izinhlobonhlobo zezinto ezisetshenziswayo ekwenzeni la mashubhu.Kodwa insimbi eguquguqukayo futhi ewusizo kakhulu iStainless Steel ngenxa yezimpawu zayo ezinhle kanye nokuqanjwa kwamakhemikhali okulinganiselwe.
Insimbi engagqwali iqukethe inani elincane le-chromium okuthi uma inyuswa impahla yensimbi ekwazi ukumelana nayo ikhule.Ukuba khona kwe-molybdenum ensimbi kuthuthukisa amandla ayo nezinye izakhiwo.I-304H iyibanga eliphezulu le-carbon Stainless Steel elikhethwa ngaphezu kwanoma yimaphi amanye amabanga e-SS ngenxa yezakhiwo zayo nokubekezelela endaweni ebanzi.Ibanga le-304H linikeza amandla aqine kakhulu, izakhiwo ezimfishane ezinkulu kanye nezimfanelo ezinhle kakhulu zokumelana nokushisa.Lesi futhi isizathu sokucosha leli banga ekwakhiweni kwamashubhu okushintsha ukushisa.
Ikhuluma ngezakhiwo zayo ezibonakalayo, i-SS 304H inikeza ukumelana okuhle kakhulu nokugqwala, ukumelana nomgodi endaweni ye-chloride, ukumelana ne-stress crack corrosion kanye nokumelana nokugqwala kwe-crevice ekushiseni okuphezulu nokucindezela.
