Cov khoom siv twg yog qhov tsim nyog rau Kev Kub Kub thiab Kev Siv Siab Siab hauv Tube Bundle Heat Exchangers?

Cov khoom siv twg yog qhov tsim nyog rau kev siv kub thiab kub siab hauv cov khoom siv hluav taws xob hauv cov khoom siv hluav taws xob?

Rau kev siv kub thiab kub siab, stainless hlau thiab npib tsib xee alloys yog cov kev xaiv ntau dua.

Stainless Hlau: Stainless hlau muaj qhov zoo corrosion kuj thiab kub-kub lub zog rau ntau yam ntawm high-temperature thiab high-pressure kev khiav hauj lwm tej yam kev mob. Tshwj xeeb, cov hlau tsis muaj cua sov uas muaj cov ntsiab lus siab dua, xws li 316L thiab 310S, muaj qhov kub thiab txias tsis kam thiab oxidation tsis kam, thiab tau siv dav hauv kev lag luam tshuaj, kho kom zoo, lub zog thiab kev lag luam nuclear.

Nickel Alloys (Nickel Alloys): Nickel alloys yog tsim los ntawm npib tsib xee thiab lwm yam alloying ntsiab lus thiab muaj kev tiv thaiv zoo corrosion thiab kub kub. Lawv ua tau zoo nyob rau hauv kub thiab corrosive ib puag ncig thiab yog siv nyob rau hauv ntau yam kev siv xws li tshuaj, refining, aerospace thiab nuclear zog. Cov nickel alloys muaj xws li Inconel, Hastelloy thiab Monel.

Cov hauv qab no yuav tsum tau txiav txim siab thaum xaiv cov khoom tsim nyog rau kev siv kub thiab kub siab:

Thermal kuj: cov khoom yuav tsum muaj qhov kub thiab txias zog thiab oxidation tsis kam los xyuas kom meej tias tsis muaj deformation los yog oxidation tshwm sim nyob rau hauv high kub.

Corrosion tsis kam: cov khoom yuav tsum muaj kev tiv thaiv zoo rau qhov kub thiab txias thiab corrosive media los tiv thaiv corrosion thiab tshuaj tua kab mob.

Cov khoom siv kho tshuab: cov khoom siv yuav tsum muaj lub zog txhua yam thiab toughness los tiv thaiv kev kub ntxhov thiab kev ntxhov siab.

Machinability: cov khoom siv yuav tsum yooj yim rau tshuab thiab vuam nyob rau hauv thiaj li yuav fabricate lub Cheebtsam ntawm lub raj bundles kub exchanger.
