Lub luag haujlwm ntawm High-Frequency Welded Finned Stainless Steel Tubes
High- zaus welded stainless hlau finned tubes yog siab - ua haujlwm kub pauv cov ntsiab lus tsim los ntawm kev sib txuas stainless hlau fins nrog lub hauv paus raj (feem ntau stainless hlau lossis carbon steel) siv lub siab - zaus induction vuam txheej txheem. Lawv lub luag haujlwm tseem ceeb yog txhawm rau txhim kho cov hluav taws xob hloov pauv tau zoo. Lawv kuj muaj cov qauv zoo, kev tiv thaiv corrosion, thiab lub neej ua haujlwm ntev, ua rau lawv haum rau ntau yam kev lag luam thiab kev siv pej xeem.
High-kub pauv tau zoo thiab tsis tshua muaj thermal kuj: Lub siab- cov txheej txheem vuam ntau zaus tsim cov hlau nplaum ntawm qhov chaw sib cuag ntawm cov fins thiab lub hauv paus raj. Lub thermal kuj tuaj yeem tswj tau nyob rau hauv qhov tsawg kawg nkaus ntawm 0.0005-0.0008 m²·K/W. Tus nqi hloov hluav taws xob yog 30%-40% siab dua li cov raj finned, thiab thaj chaw sib pauv cua sov yog 4-10 npaug ntau dua li cov hlab ntsha liab qab. Lub tshav kub hloov pauv coefficient nce mus txog 80-120 W / (m²·K), ua kom cov cuab yeej ua kom muaj kev ruaj ntseg thermal efficiency ntau dua 92% hauv chav dej, dej kub, lossis nruab nrab-tsawg kub pov tseg thaum tshav kub kub rov qab scenarios. Corrosion Resistance thiab Strong Adaptability to Operating Conditions: Cov khoom siv stainless hlau (xws li 304 lossis 316L) muab kev tiv thaiv corrosion zoo heev, tiv taus cov kua qaub tsis muaj zog thiab alkali ib puag ncig lossis chloride ion corrosion. Kev khiav hauj lwm kub ntau yog -196℃rau 900 degree, thiab lub siab tsis kam mus txog 1.0-8.0MPa. Nws yog tsim rau corrosive ib puag ncig los yog high-pressure, high-temperature tej yam kev mob xws li tshuaj nroj tsuag thiab offshore platforms. Piv txwv li, nws cov kev pab cuam lub neej tuaj yeem ncav cuag 15-20 xyoo nyob rau hauv ntug dej hiav txwv sab nraum zoov tshav kub hloov chaw.
Cov qauv siv tau ntev thiab lub neej ntev: Kev sib txuas ntawm metallurgical ntawm cov fins thiab lub hauv paus raj ua kom lub zog sib txuas ntawm 150-200MPa. Nws muaj zog vibration kuj; Txawm tias muaj qhov amplitude Tsawg dua lossis sib npaug li 0.5 hli, cov fins tsis xoob tom qab ntau xyoo ntawm kev ua haujlwm tas mus li, thiab kev ua haujlwm poob qis dua 5%. Kev tu tsuas yog yuav tsum tau ntxuav cov plua plav hauv lub sijhawm, txo qhov kev tu ncua ntau dua 40% piv rau cov raj finned ib txwm. Multi-Scenario Applications thiab Energy-Txuag Cov txiaj ntsig: Siv dav hauv kev lag luam pov tseg thaum tshav kub kub rov qab (xws li, txhim kho thermal efficiency ntawm boiler cua preheaters hauv kev lag luam fais fab los ntawm 3%-5%), tshuaj reactor txias, thaj chaw hauv nruab nrab cua sov (tswj chav kub hloov pauv hauv cov tsev loj hauv ± 1% kev ua haujlwm tsis ua haujlwm), photovoltaic inverter txias). Nws kuj tseem pab txhawb kev txuag hluav taws xob thiab txo cov pa roj carbon monoxide los ntawm kev tsim lub teeb yuag thiab qis-qib khib nyiab rov qab.
