Rwb thaiv tsev rau cov kav dej thiab nws cov variants. thermal rwb thaiv tsev uas yuav tsum tau

Pipelines ntawm ntau yam systems, raws li ib tug txoj cai, muaj ib tug ntau dua ntev. Lawv qhov chaw nyob ob leeg rau ntawm qhov chaw thiab underground. Nws yog yog li ntawd tseem ceeb heev rau cov hauj lwm zoo ntawm cov rwb thaiv tsev ntawm kev sib txuas lus los ntawm tus mob khaub thuas thiab lwm yam sab nraud influences yog heev. Rwb thaiv tsev rau cov kav dej copes nrog no ua hauj lwm.

lub sij hawm rwb thaiv tsev

Cov loj tshaj plaws thiab qho teeb meem - nws yog cia kom khov ntawm cov kav dej nyob rau hauv txoj kev seem ntawm lub raj dej thiab nyob rau hauv unheated chav. Ntse siv rwb thaiv tsev system chiv tshaj los mus tshem tawm cov teebmeem.

Thermal rwb thaiv tsev yeeb nkab tiv thaiv kev sib txuas lus los ntawm xeb hnyuj hnyo rau cov hlau qhov chaw ntawm lub cev raws li ib tug tshwm sim ntawm mus tas li hws. Raws li ib tug tshwm sim, lub raj thinner thiab tsis.

Rwb thaiv tsev rau cov kav dej yuav pab tiv thaiv kom txhob kub tsis tau. Khaws qhov kub thiab txias nyob rau hauv cov kav dej ntawm lub cua sov system, tus tswv tsev yuav tsum tau txo nqi hluav taws xob nqi.

Yuav tsum muaj rau lub rhaub yeeb nkab

• Tsis tshua muaj thermal conductivity, yuav txo tau kub tsis tau.
• High durability thiab ntev kev pab cuam lub neej.
• Ib tug dav kub ntau. Sudden kub hloov tsis cuam tshuam lub zog ntawm cov rwb thaiv tsev, tshwj xeeb yog thaum nws los txog rau ib tug dej kub yeeb nkab txheej txheem nyob rau sab nraum.
• Txhim khu kev qha rwb thaiv tsev, uas yuav tsis kis tau los ntawm lub taub rhaub dej los yog condensate.
• High-zoo rwb thaiv tsev rau cov kav dej yog tsis raug mus rau ib puag ncig kev nyuaj siab.
• Hluav Taws kev ruaj ntseg. Thaum rwb thaiv tsev piping systems nyob rau hauv qhov chaw nyob qhov twg cov hluav taws yuav tshwm sim (da dej, chav thiab thiaj li nyob. D.) Yog siv xwb incombustible cov ntaub ntawv.
• Yooj yim rau nruab. Nyob rau hauv industrial siv los yog nyob rau hauv nws tus kheej-sov yog ib tug meej ntxiv.

ntau yam ntawm cua sov

• Mineral wool los yog basalt rwb thaiv tsev. Qhov no high-zog cov ntaub ntawv uas nrog ib tug raug ntev lub neej. Cov kub ntau ntawm kev siv yog dav heev - los ntawm -60 ° C rau +200 ° C. Yooj Yim thiab zoo adhesion. Tsis tas li ntawd tam nrog iav ntaub plaub los yog ntawv ci.
• Iav ntaub plaub muaj ib tug uas tsis muaj thermal conductivity - los ntawm 0,028 mus 0,034 W / m. Nws yog ib tug uas tsis yog-combustible cov ntaub ntawv thiab tsis raug mus rau high kub. Muaj tsuas yog ib drawback - heev hygroscopic, yog li ntawd, yuav tsum tau ib tug ntxiv txheej ntawm insulating cov ntaub ntawv uas nyob sab nraum. Raws li rwb thaiv tsev rau cua sov hlab siv heev heev, ua ib tug ntawm qhov zoo tshaj plaws cov ntaub ntawv - los ntawm 60 mus rau 80 rubles ib 1 kg.

• Rwb thaiv tsev ntawm foamed polystyrene, nyob rau hauv qhov tseeb, tib ua npuas ncauj, tab sis nyob rau hauv ib tug daim ntawv. Nws yog zoo mus siv rau ib tug kub ntawm los ntawm -80 ° C rau + 180 ° C. Nws thermal conductivity yog siab tshaj yav dhau los cov ntaub ntawv - 0.05 W / m. Dua li no, nws kuj tseem muaj feem sov zoo. Qhov zoo xws li yooj yim ntawm installation - yog manufactured nyob rau hauv daim ntawv ntawm cov hemispheres, uas yog heev tsuas qhwv ib tug seem ntawm cov yeeb nkab thiab muab ib nrab. Cov txheej txheej ntawm rwb thaiv tsev muaj ib tug txheej cover uas tsub kom nws kav ntev. Tus nqi yog nyob rau hauv lub cheeb thiab cov ntaub ntawv uas tuab. Lub thinnest rwb thaiv tsev nqi txog 60 rubles. ib square meter.
• Rwb thaiv tsev rau cov kav dej "plhaub" ua los ntawm polyurethane thiab yog zoo nyob rau hauv nws cov khoom rau cov ua npuas ncauj. Nws muaj ob halves, li walnut zoo li, uas yog superimposed on lub raj los ntawm ob sab thiab muaj nrees tsau hlau. Nrog ib tug ntau dua kev ceev thiab kwv yees li tib yam coefficient ntawm thermal conductivity, qhov no cov ntaub ntawv uas yog yooj yim los mus tso txhua yam raug nyiaj txaus thermally insulating ntawm kub ntawm -180 ° C rau +130 ° C. Thaum dismantling retains tag nrho ntawm nws insulating zog, li ntawd, nws thiaj yuav reused. Nws yuav kav txog 30 xyoo. Tus nqi ntawm cov rwb thaiv tsev mas nws txawv ntawm 200 mus rau 1000 rubles, nyob ntawm seb qhov luaj li cas ntawm cov khoom.

• Pheej yig thiab yooj yim rwb thaiv tsev - polyethylene ua npuas ncauj. Ua tsaug rau cov zoo-mesh qauv khaws sov zoo. Nws thermal conductivity tsis siab tshaj 0.05 W / m. Kev khiav hauj lwm ntau yam kub yog los ntawm -50 ° C rau +90 ° C. Nws muaj ib tug uas tsis muaj qhov hnyav thiab thickness, thiab yog li txuag lub cheeb tsam. Check, yuav kav ntau tshaj li 100 xyoo. Tus nqi nyob rau ntawm daim ntawv thickness thiab yog kwv yees li 160-200 rubles ib 'meter'.

• Ib tug ntawm cov feem ntau niaj hnub rwb thaiv tsev ntaub ntawv yog ib tug kua rwb thaiv tsev rau cov kav dej. Nws muaj qhov qis thermal conductivity - 0.01 W / m, yog diluted nrog dej thiab yog yooj yim hos. Nyob rau hauv qhuav daim ntawv nws tiv thaiv los ntawm noo noo, zoo yam tshav kub. Nqe no 350-400 rubles ib liter.

mounting

Nws yog lig nyob rau dab tsi nws yuav siv sij hawm rwb thaiv tsev. Rau cua sov kav kheev siv iav ntaub plaub, thiab cov txheej txheem ntawm nws daim ntawv thov no yooj yim heev. Plast yog lub qhov txhab nyob rau hauv lub raj thiab tsau nrog nplaum kab xev ib ncig ntawm lub perimeter.
