Dab tsi yog Cov Khoom Siv Zoo Tshaj Plaws Rau Cov Hluav Taws Xob Hluav Taws Xob?

Dab tsi yog cov khoom siv zoo tshaj plaws rau lub tshav kub exchanger plhaub?

Qhov kev xaiv ntawm cov khoom siv zoo tshaj plaws rau lub plhaub cua sov yog nyob ntawm ntau yam, suav nrog hom kua dej, kev ua haujlwm (kub thiab siab), thiab muaj peev xwm ua rau corrosion lossis fouling. Ntau yam khoom siv feem ntau yog siv rau cov khoom siv hluav taws xob hloov hluav taws xob, txhua tus muaj nws tus kheej zoo thiab kev txwv. Cov ntaub ntawv tsim nyog tshaj plaws rau ib lub thawv ntawv yuav txawv nyob ntawm daim ntawv thov tshwj xeeb.

Qee cov ntaub ntawv uas siv rau cov khoom siv hluav taws xob sib txawv xws li:

1. Carbon Steel: Cov pa roj carbon steel yog cov khoom siv dav siv rau cov khoom siv hluav taws xob hloov hluav taws xob vim nws cov nqi-zoo, muaj thiab cov khoom siv zoo. Txawm li cas los xij, nws muaj kev cuam tshuam rau corrosion, tshwj xeeb tshaj yog nyob rau hauv daim ntawv thov uas muaj corrosive kua los yog kub kub.

2. Stainless hlau: Stainless hlau muaj zoo heev corrosion kuj, ua rau nws haum rau tshav kub exchangers uas lis corrosive kua los yog ua hauj lwm nyob rau hauv corrosive ib puag ncig. Feem ntau siv cov qib stainless hlau muaj xws li 304, 316 thiab duplex stainless hlau.

3. Copper-nickel alloys: Copper-nickel alloys, xws li Cu-Ni 90/10 thiab Cu-Ni 70/30, paub txog lawv zoo heev corrosion kuj nyob rau hauv marine thiab seawater daim ntaub ntawv. Lawv feem ntau siv hauv marine heat exchangers.

4. Titanium: Titanium yog ib lub teeb yuag thiab corrosion-resistant khoom haum rau corrosive chemical ib puag ncig lossis qhov hnyav yog qhov tseem ceeb. Txawm li cas los xij, titanium kuj tseem kim dua piv rau lwm cov ntaub ntawv.

5. Nickel Alloys: Nickel-based alloys, xws li Inconel thiab Hastelloy, raug xaiv rau lawv cov kev tiv thaiv corrosion zoo tshaj thiab kev siv kub. Lawv feem ntau yog siv rau hauv cov khoom siv hluav taws xob uas siv cov khoom siv hluav taws xob thiab cov dej kub kub.

6. Aluminium: Aluminium feem ntau yog siv rau hauv cov cua txias cua kub exchangers vim nws cov thermal conductivity zoo heev thiab lub teeb yuag. Nws yog feem ntau siv nyob rau hauv finned tube tshav kub exchangers.

Kev xaiv ntawm cov khoom siv plhaub zoo tshaj plaws yuav tsum coj mus rau hauv tus account yam xws li cov khoom ua kua, kev ua haujlwm kub thiab siab, nrog rau cov kev lag luam tshwj xeeb thiab ib puag ncig. Kev nkag siab zoo ntawm daim ntawv thov yuav tsum tau ua thiab ua tib zoo engineering yuav ua kom muaj kev ua tau zoo, kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv hluav taws xob.
