Ol 'spiral heat exchanger' em ol i save yusim planti long ol kemikel, marasin, kaikai, na eneji sekta bikos ol i gat liklik straksa na gutpela hat trensfe. Gutpela wok na sevis laip bilong ol i save kamap long ol samting ol i makim. Ol kain kain wok kondisen i nidim ol samting we i stret long ol samting bilong mekim ol i no ken bagarap, strong, na i no gat bikpela pe bilong en.
Kabon stiel na low-aloi stiel em ol as samting bilong wokim ol 'spiral heat exchanger', we i gutpela long ol samting we i no save bagarapim o i save bagarapim liklik (olsem wara-i go long-wara hat eksens). Ol dispela samting i no gat bikpela pe na i gat bikpela strong bilong masin, tasol ol i mas kisim tritmen long pes bilong en (olsem 'galvanizing' o 'coating') long mekim wok bilong ol i stap longpela taim. Long ol wok we i gat bikpela hat na presa, ol 'alloy steel' (olsem Q345R) inap long helpim 'creep' na 'oxidation resistance' bikos ol i putim ol samting olsem 'molybdenum' na 'chromium'.
Ol 'stainless steels' (olsem 304 na 316L) em ol bikpela samting bilong wokim ol 'stainless steel spiral heat exchanger', na ol i gutpela long ol 'media' we i gat 'chloride ions', 'acids' na 'bases', o ol 'sanitary conditions. 316L, bikos i gat 'molybdenum' insait long en, em i no inap long bruk na ol i save yusim planti taim long ol marasin ol indastri bilong kaikai. Ol 'duplex stainless steels' (olsem 2205) i gat bikpela strong wantaim strong bilong sakim 'chloride stress corrosion', na dispela i mekim ol i gutpela long ol wara we i gat bikpela hat na i gat 'chloride ions' insait long en.
Ol 'nickel-based alloys (olsem Hastelloy C276 na Inconel 625) em ol i wokim bilong yusim long ol ples we i save bagarapim ol samting, olsem ol strongpela asid (salfurik asid na haidroklorik asid), hai-temperature na hai-presa haidrojen, o ol sistem bilong rausim sol. Maski ol dispela samting i gat bikpela pe, ol i save sakim 'intergranular corrosion' na 'high-temperature oxidation' na planti taim ol i save yusim long ol bikpela wok olsem 'petrochemicals' na lukautim envairomen.
Titanium em i gutpela samting bilong senisim hat bilong solwara. Bikos em i gat gutpela 'chloride ion corrosion resistance' na em i no hevi tumas, ol i save yusim long ol sip na ol pawa plent long nambis. Na tu, ol samting we i no bilong ain olsem 'graphite' na 'ceramics', maski ol i no inap bagarap, ol i save bruk bruk tu na ol i ken yusim long ol liklik wok tasol.
Taim ol i makim ol samting bilong wokim samting, ol i mas tingim gut ol samting bilong en, tempereja, presa, na pe bilong en. Ol disaina bilong ol 'spiral heat exchanger' i mas skelim gut wok na 'economic' bilong en long rot bilong 'corrosion testing' na 'engineering experience' bilong mekim ol ikwipmen i wok longpela taim na i stap gut.
