ASTM A312 stainless hlau puag khoom muaj 18% -20% chromium thiab 8% -13% npib tsib xee (nrog TP316L muaj ntxiv 2% - 3% molybdenum). Cov ntaub ntawv ntom ntom chromium oxide passivation zaj duab xis tsim rau ntawm nws qhov chaw, tiv thaiv corrosion los ntawm sulfides (H₂S), chloride ions (Cl⁻), thiab acidic media tam sim no hauv cov roj thiab roj ib puag ncig, yog li ua tau raws li cov qauv kev tiv thaiv corrosion ntawm cov roj thiab roj kev lag luam.
Lub Stainless Wrapped Finned Tube siv qhov txias -wrapping thiab siab- zaus vuam txheej txheem, kom ntseeg tau tias muaj kev sib tshuam ntawm cov fins thiab lub hauv paus raj nrog qhov sib txuas ntawm tsawg dua lossis sib npaug li 0.05 hli. Validated los ntawm kev vibration testing, cov fins qhia tsis tau tsiv los yog detachment txawm nyob rau hauv complex kev khiav hauj lwm tej yam kev mob.

FAQ
Q: Dab tsi yog kauv - qhov txhab finned tube, thiab nws yuav ua li cas txhawm rau txhim kho cov cua sov ua haujlwm?
A: Kauv- cov kab mob finned tubes ua rau thaj chaw sib cuag ntawm cov khoom siv hluav taws xob los ntawm kev sib txuas ceev nrooj ntawm cov hlua hlau txuas txuas (fin) nyob ib puag ncig sab nraud ntawm lub hauv paus raj. Hauv kev siv roj thiab roj, qhov kev teeb tsa no txhawb nqa kev kub ntxhov hauv cov kua dej sab nraud uas ntws los ntawm lub plhaub sab, yog li txo qis thermal kuj.
Q: Cov hlau tshwj xeeb puas tuaj yeem siv rau ob lub hauv paus raj thiab cov fins?
A: Yog, duplex stainless hlau, super duplex stainless hlau, Inconel, thiab 254 SMO yog tag nrho cov kev xaiv.
Q: Koj puas tuaj yeem tsim khoov finned raj rau siv hauv U-tube bundle heat exchangers?
A: Yog lawm, peb tuaj yeem tsim U-bent finned tube sib dhos. Peb tuaj yeem ua kom haum cov raj ncaj ncaj ntev txog li 27,000 mm thaum tswj xyuas qhov zoo tshaj plaws fin ntom. Los ntawm kev ua tib zoo tswj lub vojvoog dabtsi yog khoov thiab siv tom qab- khoov kho cua sov, peb xyuas kom meej tias qhov khoov tsis muaj qhov txhab thiab cov phab ntsa ntau dhau.
