Say pampili na materyales parad saray spiral tubes (core heat exchange element) na spiral heat exchanger. Say pampili et mandedepende ed taloran manunan bengatla: say katangian na medium (ka-corrosiveness, temperatura, pressure), say nakaukolan ya heat exchange efficiency, tan say badyet ed gastos. Nepeg ya iyuna so pangibalanse ed resistensya ed corrosion, thermal conductivity, tan biskeg na istruktura. Say onggendan so detalyadon deskripsion na saray kaslakan ya uusaren a klasipikasyon na materyales, kablian, tan saray onaplikan senaryo:
Saray Kaslakan ya Uusaren ya Manunan Materyales (Onaplika ed Kaslakan ya Kondisyon na Pantratrabaho)
1. Saray manunan katangian na carbon steel (Q235, 20# steel):
Atagey so thermal conductivity to (manga 45 W/(m·K)), abeba so gastos, mainomay ya iproseso tan i-welding, tan maong so structural strength to; Makapuy so resistensya tod corrosion tan matukoy labat ed saray ag--corrosive, malinis iran pluido (singa say malinis a danum, saturated steam, tan industrial gases/acquids ya anggapoy alkalis).
2. Stainless steel (304, 316L, 321) Saray manunan katangian:
Atagey ya resistensya ed corrosion (304 ya ag-onkukurang ed makapuy ya corrosion, 316L ya ag-onkukurang ed mabiskeg ya corrosion, walay molybdenum to, 321 ya ag-onkukurang ed intergranular corrosion); Say kalkalnan thermal conductivity (304 manga 16 W/(m・K), medyo abeba nen say carbon steel), atagey ya resistensya ed petang (continuous operating temperature Less of o mipara ed 600℃), mainomay ya linisan, makaabot ed saray estandarte na kalinisan na kakanen/tambal; Mas atagey so gastos nen say carbon steel, kalmado so pankaukolan ed proseso na welding.
Saray materyales ya atagey so performance da ya ag-onkupas (matukoy ed saray kondisyon na pantratrabaho ya makapabaing a maong)
1. Titanium alloys (TA1, TA2)
Saray manunan kabiangan: Mabiskeg so resistensya to ed corrosion (sarag ton sungdoan so ngalngalin amin ya acid tan alkali media, kaiba lay concentrated hydrochloric acid, sulfuric acid, chlor-alkali solution, tan danum na dayat), tan anggapoy peligro na pitting corrosion odino crevice corrosion.
2.Hastelloy (C-276, C-22)Manunan katangian:
Corrosion-resistant ultra-stainless steel (resistant ed oxidizing acids, reducing acids, fluorine/chlorine-containing media, tan atagey a temperatura na corrosion); Atagey ya resistensya ed petang (Abeba o mipara ed 800 degree), atagey ya biskeg, matukoy ed arawrawin kondisyon na pantratrabaho; Atagey so gastos to (ngalngalin 1.5-2 beses ya mas baleg nen say titanium alloys), tan mairap ya iproseso.
Gansa tan gansa ya alloy (puron gansa T2, gansa H68, cupronickel B30) Saray manunan katangian:
Atagey a tuloy so thermal conductivity (ngalngalin 401 W/(m·K) parad gansa, masulok ya 20 beses nen say stainless steel), ya manresulta ed sankaabigan ya heat exchange efficiency; Say gansa et walaan na moderate ya resistensya ed corrosion (matukoy parad neutral media ya anggapoy oxidation), say gansa et walaan na medyo abeban resistensya ed corrosion, tan say cupronickel (copper-nickel alloy) et ag-onkulang ed danum na dayat tan chlorine- ya walaan na media corrosion; Katamtaman so gastos (mas atagey nen say carbon steel, abeba nen say stainless steel), tan mainomay ya iproseso tan ibaluktot (matukoy parad spiral winding).
