Qhov no steam insulated pipeline yog prefabricated, ncaj qha- faus "steel-hauv-steel" cov khoom tsim los ntawm Xingbang tshwj xeeb rau siab -kub xa hluav taws xob (150℃txog 350℃). Muaj peev xwm tiv taus kev ua haujlwm siab txog li 2.5 MPa, nws yog qhov tsim nyog rau cov ntawv thov xws li lub nroog cov cua sov hauv nroog, kev ua haujlwm petrochemical, thiab chaw ua si hauv chaw ua haujlwm. Cov khoom lag luam muaj nyob rau hauv ob qho tib si "sab hauv- zawv zawg" thiab "sab nraud- zawv zawg" kev teeb tsa. Nws txwv qhov kub thiab txias tsis pub dhau 3℃ib mais thiab txo cov cua sov los ntawm ntau tshaj 40% piv rau cov kav dej ib txwm siv. Lub casing sab nrauv nta 3PE los tiv thaiv- tiv thaiv corrosion thiab lub ntse ntse saib xyuas, nrog rau kev tsim lub neej ntawm 25 txog 30 xyoo.

Sliding Structure
Raws li txoj kev ua kom haum thermal expansion hloov chaw ntawm cov cab kuj steel yeeb nkab, cov khoom muaj nyob rau hauv ob qho kev teeb tsa:
Internal sliding hom:Cov cab kuj steel yeeb nkab swb nyob rau hauv lub rwb thaiv tsev txheej. Cov qauv no yog compact thiab nruab nrab nqi, ua rau nws yog ib qho kev xaiv rau domestic tej yaam num. Nws yog qhov tsim nyog rau kev ua haujlwm dav dav, thiab nws qhov kev ua haujlwm noo noo feem ntau ua tau raws li qhov yuav tsum tau ua.
Sab nrauv sliding hom:Cov cab kuj steel yeeb nkab thiab cov txheej rwb thaiv tsev swb raws li ib chav tsev tiv thaiv cov phab ntsa sab hauv ntawm lub qhov rooj sab nrauv, nrog rau qhov dav dav ntawm huab cua sib txawv ntawm cov txheej txheem rwb thaiv tsev thiab sab nrauv. Cov qauv tsim qauv no muab kev soj ntsuam kev ntxhov siab ncaj qha thiab cov dej noo zoo dua -venting peev xwm; nws tau txais kev pom zoo thoob ntiaj teb thiab dhau los ua qhov kev xaiv tseem ceeb hauv kev lag luam hauv tsev. Nws yog qhov tshwj xeeb tshaj yog tsim rau cov haujlwm uas muaj cov dej hauv av siab thiab cov kev cai nruj heev rau kev tso dej noo.
Qhov Zoo Tshaj Plaws
Siab -Tsuas Kub thiab Siab -Kev Ua Haujlwm Siab
Haum rau qhov kub thiab txias txog li 350℃thiab kev khiav hauj lwm siab txog li 2.5 MPa, nrog lub siab tawg tsawg kawg yog peb zaug ntawm kev khiav hauj lwm siab, ua tau raws li qhov xav tau ntawm siab - qhov kub ntawm chav thauj khoom hauv kev lag luam thiab hauv nroog.
Kev ua haujlwm siab thiab txuag hluav taws xob nrog tsawg kawg cua sov poob
Nta muaj ntau- txheej txheej gradient rwb thaiv tsev ua ke nrog ib txheej aluminium foil reflective txheej. Thaum tshav kub kub poob yog txo los ntawm 70% piv rau cov kav dej ib txwm muaj, qhov kub thiab txias poob qis dua 3℃ib mais, uas ua rau cov nqi hluav taws xob tseem ceeb thaum lub sijhawm ua haujlwm ntev -.
Zoo heev Corrosion Resistance thiab lub neej ua haujlwm ntev
Sab nrauv steel casing yog tiv thaiv los ntawm 3PE los yog fusion-bonded epoxy (FBE) coatings thiab cathodic tiv thaiv technology, zoo tiv thaiv corrosion ntawm av thiab av. Lub neej kev pab tsim yog 25-30 xyoo.
FAQ
Q: Qhov txawv ntawm qhov cub no yog dab tsi - insulated pipeline thiab txheem polyurethane - insulated piping?
A: Tus qauv polyurethane- cov kav dej insulated yog tsim rau qis dua - cov xov xwm kub (xws li dej kub, Tsawg dua lossis sib npaug li 140℃). Piv txwv li, prefabricated underground steam pipelines yog tsim los rau siab -kub chav. Lawv siv cov qauv sib xyaw ua ke sib txuas cov khoom siv hluav taws xob tsis zoo (xws li txhuas silicate lossis iav ntaub plaub) nrog polyurethane, muab cov kub ua haujlwm siab dua, cov qauv ntau dua, thiab qib siab dua ntawm kev tiv thaiv corrosion.
Q: Qhov no puas tuaj yeem ua rau lub qhov cub- insulated pipeline txuas nrog cov kav dej los ntawm lwm cov tuam ntxhab?
A: Yog, kev sib txuas yog ua tau, tab sis interface compatibility yuav tsum tau txiav txim siab. Cov lus qhia tshwj xeeb hais txog cov yeeb nkab txoj kab uas hla, cov ntaub ntawv rwb thaiv tsev, thiab txheej txheej tiv thaiv -corrosion txheej yuav txawv ntawm cov tuam txhab. Peb pom zoo kom txheeb xyuas cov ncauj lus kom ntxaws ntawm ob tog ua ntej kev sib txuas. Yog tias tsim nyog, Xingbang cov kws tshaj lij tuaj yeem muab rau ntawm - qhov chaw qhia kev sib koom ua ke kom ntseeg tau tias kev sib txuas zoo.
Q: Dab tsi yog Xingbang cov peev txheej hauv cov khoom lag luam no?
A: Raws li tus neeg koom nrog hauv kev tsim cov qauv kev lag luam (CJ / T 246, CJJ / T 104), Xingbang tuav ntau dua 130 lub teb chaws patents thiab ua haujlwm tsib lub xeev - theem R & D platforms, suav nrog Hebei Provincial Industrial Technology Research Institute for Thermal Insulation Pipelines. Nws qhov chaw sim yog CNAS- tau lees paub thiab muaj peev xwm ua tau zoo ntawm kev ntsuas kev rwb thaiv tsev thiab tiv thaiv- txheej txheej corrosion, ua kom cov khoom zoo.
