Thaum tshav kub kub-insulating yeeb nkab

Tianjin Lefin Industrial Co., Ltd yog ib lub tuam txhab muaj kev paub ntau tshaj plaws thiab cov chaw muag khoom ntawm cov cua sov-insulating yeeb nkab hauv Suav teb. Thov koj xav tias dawb mus yuav cov cua kub zoo-insulating yeeb nkab los ntawm peb lub hoobkas. Kev pabcuam zoo thiab tus nqi tsim nyog muaj.

Lub tshav kub-cov yeeb nkab insulating yog cov yeeb nkab steel uas tau raug kho tshwj xeeb rwb thaiv tsev. Nws lub luag haujlwm tseem ceeb yog uatxo qhov kub poobntawm lub raj xa dej thaum lub sij hawm kev thauj mus los ntawm kev tshaj tawm (xws li dej kub, chav dej, roj av, thiab lwm yam), kom ntseeg tau tias qhov kub ntawm qhov nruab nrab ua tau raws li qhov yuav tsum tau ua, thiab tiv thaiv kev cuam tshuam ntawm sab nraud ib puag ncig ntawm cov kav dej.

Lub tshav kub- cov kav dej insulating feem ntau muaj ob hom qauv, uas muaj feem cuam tshuam rau kev ua haujlwm sib txawv:

1. Steel-bonded steel composite rwb thaiv tsev yeeb nkab

Cov qauv no feem ntau yog siv rauthauj siab -kub chav(txog 150℃- 450℃) thiab lwm yam siab -kub tawm. Nws txais yuav "tube-hauv-tube" tsim. Nyob ntawm txoj kev sib txawv zawv zawg sab hauv, nws tau muab faib ua ob hom: inner zawv zawg homthiabsab nrauv zawv zawg hom.

◦Hauvner sliding hom:Los ntawm sab hauv mus rau sab nraud, nws yog cov yeeb nkab ua haujlwm steel, silicagel / txo cov txheej txheem, microporous calcium silicate rwb thaiv tsev txheej, polyurethane rwb thaiv tsev txheej, thiab txheej txheej sab nraud yog lub tsho sab nrauv steel yeeb nkab thiab txheej txheej tiv thaiv -corrosion. Nws tus yam ntxwv yog tias tus rwb thaiv tsev txheejswb ua ker nrog cov yeeb nkab ua haujlwm hauv lub tsho sab nrauv steel yeeb nkab.

◦ Sab nrauv sliding hom: Cov txheej txheem txheej txheem los ntawm sab hauv mus rau sab nrauv muaj cov yeeb nkab ua haujlwm, siab -kub iav wool rwb thaiv tsev txheej, aluminium foil reflective txheej, cua rwb thaiv tsev txheej, thiab cov yeeb nkab steel tiv thaiv sab nraud. Cov qauv no tso cai rau cov yeeb nkab steel ua haujlwmdawb do nthuav thiab cog lus thermally nyob rau hauv lub rwb thaiv tsev txheej.

Qhov zoo ntawm steel- cov kav dej sib xyaw ua ke nyob hauv lawvsiab zogthiabkev pabcuam ntev lub neej. Lawv tuaj yeem yogncaj qha faus undergroundthiab tsis tas yuav tsum tau tsim cov yeeb nkab loj trench. Lawv yog tshwj xeeb tshaj yog haum rau siab -kub chav pipeline tej yaam num.

2. Polyurethane rwb thaiv tsev yeeb nkab
Qhov no yog ib tug dav siv qauv nyob rau hauv tam sim no, feem ntau pom nyob rau hauv centralized cua sov, roj tsheb thauj mus los, thiab lwm yam., rau lubkis tau tus mob nruab nrab -kub media (feem ntau yog li ntawm -50℃txog 150℃). Nws txais kev tsim peb txheej classic:

◦ Thawj txheej: Cov kav dej ua haujlwm: Nyob rau hauv ncaj qhativ tauj nrog lub nruab nrab thauj, seamless steel kav, kauv steel kav, thiab lwm yam tuaj yeem xaiv raws li qhov xav tau.

◦ Ob txheej:Polyurethane rwb thaiv tsev txheej: Los ntawm high-pressure foaming technology, tawv polyurethane ua npuas ncauj yas yog txhaj rau hauv cov kab noj hniav uas tsim los ntawm cov yeeb nkab ua hauj lwm thiab txheej tiv thaiv txheej. Cov khoom no muaj ib qhotsis tshua muaj thermal conductivity, uas tuaj yeem txo qhov kub poob.

◦ Peb txheej:High- ntom polyethylene (HDPE) txheej tiv thaiv: Ua ntej- cov kav dej yas tsim, lawv txoj haujlwm yog los tiv thaiv cov txheej txheem rwb thaiv tsev sab hauv los ntawm kev puas tsuaj los ntawm cov khoom siv tawv, thiab ua lub luag haujlwm tseem ceeb hauvnti-corrosion thiab waterproofing.

Piv nrog cov tsoos trench lossis overhead nteg cov kav dej, cov cua sov-insulating yeeb nkab muaj qhov zoo:

• Zog-txuag thiab siv tau:

Qhov kub poob tsuas yog li 25% ntawm cov kav dej ib txwm muaj, uas tuaj yeem ua taucawmib tug loj npaum li cas ntawmzogdhau lub sij hawm ntev.

• Kev txo nqi them nqi:

Nws ua tautxo tus nqi ntawm qhov projectlos ntawm 10% mus rau 25%, txo qhov nyiaj ntawm lub ntiaj teb kev khawb thiab kev siv pob zeb (txog 50% lossis ntau dua), thiab txo lub sijhawm tsim kho los ntawm kwv yees li 50%.

• Ntev lifespan thiab stability:

Nrog rau kev txhim kho thiab kev siv kom raug, lub neej kev pab cuam tuaj yeem ncav cuag 30 txog 50 xyoo, thiab cov nqi kho mob tsawg.

• Kev txawj ntse kev nyab xeeb:

A leakage tswb system tuaj yeem teeb tsa up. Nyob rau hauv cov ntaub ntawv ntawm ib qho kev xau ntawm ib qho chaw, nws tuaj yeem pom thiab pom tseeb qhov chaw tsis raug, ua kom muaj kev nyab xeeb ntawm cov kav xa dej.

Vim nws qhov kev ua tau zoo heev, cov cua sov- cov yeeb nkab insulating yog dav siv nyob rau hauv ntau yam teb:

• Hauv nroog centralized cua sov kav
• Industrial pipelines rau roj av, tshuaj,thiab lwm yam (xws li kev thauj mus los ntawm cov roj kub)
• Cov kav dej txias thiab dej kub ntawm qhov nruab nrab cua txias system
• Municipal cavnplhaib tej yaam numthiab lwm yam xwm txheej uas yuav tsum tau muaj kev tiv thaiv cua sov thiab kev khaws cia txias

Hauv cov ntsiab lus yooj yim, koj tuaj yeem xav txog cov rwb thaiv tsev hlau ua "thermal insulation khob" tailor-ua rau cov kav dej. Nws tus nqi tseem ceeb nyob hauvusing ib tug tshwj xeeb composite qauv rauxyuas kom muaj zogthaum ua tiavkev rwb thaiv tsev zoo, ntev - tiv thaiv corrosion, thiabyooj yim siv.

Thaum kawg, qhov no ua rau kev txuag hluav taws xob, txo nqi, thiab txo cov nuj nqis tag nrho.
