Tuam Tshoj thermal rwb thaiv tsev steel yeeb nkab Hoobkas
Thermal rwb thaiv tsev pipeline yog dav siv nyob rau hauv cov kua thiab roj kis tau tus mob pipeline network, tshuaj pipeline thermal rwb thaiv tsev engineering, roj av, tshuaj kev lag luam, central cua sov network, central cua txias qhov cua pipeline, municipal engineering, thiab lwm yam Steel jacketed steel composite rwb thaiv tsev steel yeeb nkab.
Cov txheej txheem thermal rwb thaiv tsev ntawm steel jacketed steel composite thermal rwb thaiv tsev steel yeeb nkab tuaj yeem muab faib ua ob pawg raws li ntau hom zawv zawg:
1.Sab hauv zawv zawg hom: cov txheej txheem thermal rwb thaiv tsev yog tsim los ntawm kev ua haujlwm steel yeeb nkab, aluminium silicate, rub txo txheej, microporous calcium silicate, thermal rwb thaiv tsev txheej, stainless hlau fastening steel sawb, aluminium foil reflection txheej, polyurethane thermal rwb thaiv tsev txheej, txheej steel yeeb nkab thiab Sab nraud los tiv thaiv corrosion txheej. Sab hauv zawv zawg hom kev txuag hluav taws xob steel yeeb nkab yog tsim los ntawm cov yeeb nkab conveying nruab nrab, cov khoom sib xyaw silicate los yog microporous calcium silicate, cov yas polyurethane ua npuas ncauj, txheej steel yeeb nkab thiab FRP plhaub tiv thaiv txheej. Thermal rwb thaiv tsev kho tshuab ntawm ntau yam yeeb nkab fittings yog mature thiab qhov zoo yog txhim khu kev qha.
2. Sab nrauv zawv zawg hom: cov txheej txheem thermal rwb thaiv tsev yog tsim los ntawm kev ua haujlwm steel yeeb nkab, iav ntaub plaub thermal rwb thaiv tsev txheej, aluminium foil reflection txheej, stainless hlau fastening steel siv, zawv zawg qhia kev txhawb nqa, cua rwb thaiv tsev txheej, sab nraud steel yeeb nkab thiab txheej txheej tiv thaiv corrosion. .

Steel jacketed steel composite rwb thaiv tsev steel yeeb nkab yog ib qho ntawm cov kav dej hauv av ncaj qha faus. Nws tseem tuaj yeem muab faus rau hauv av yam tsis muaj cov qauv ua vaj tse, uas yog, thermal expansion ntawm cov yeeb nkab ua haujlwm yog nqa tawm hauv cov yeeb nkab sab nraud, uas txo cov nqi khoom, txo cov hnub tsim kho, ua kom muaj kev nyab xeeb ntawm cov kav dej cua sov, thiab tuaj yeem ua tau. muaj kev nyab xeeb dua thiab dav siv nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias, tshwj xeeb tshaj yog tsim rau kub kub chav pipeline tej yaam num. Qhov kev pabcuam kub tuaj yeem ncav cuag 150 ℃ - 450 ℃. Cov yeeb nkab kawg yog feem ntau kaw nrog polyethylene zaj duab xis los yog peb-txheej PE txias winding daim kab xev tiv thaiv kom tsis txhob ya raws los yog dej los ntawm kev nkag mus ua ntej installation los yog thaum lub sij hawm tsim kho. Multi-txheej staggered khi ntawm cov ntaub ntawv thermal rwb thaiv tsev zoo txo qhov kub poob. Nyob rau tib lub sijhawm, kev tswj xyuas tau raug coj los rau ntawm lub tes tsho sab nrauv kom tiv thaiv kev tsim ntawm tus choj txias, thiaj li ua kom qhov ntsuas kub ntawm lub tes tsho sab nrauv los tiv thaiv corrosion txheej. Multilayer aluminium foil reflective txheej yog qhwv nrog cov khoom siv thermal rwb thaiv tsev, uas txo cov cua sov thiab ua rau cov kav dej ntau dua kev lag luam thiab tsim nyog. Lub qhov dej ntws tau raug kaw tag nrho, nrog cov qauv yooj yim, cov qauv tsim nyog, kev nyab xeeb thiab kev ntseeg tau. Cov dej xau cov yeeb nkab ntawm cov hlau casing tuaj yeem tsis tsuas yog tso cov pa ntub dej hauv lub sijhawm, tab sis kuj tseem ua lub tswb ceeb toom yeeb nkab rau kev ua haujlwm txhua hnub. Lub thermal them nyiaj ntawm cov raj xa dej tau txais cov txiaj ntsig zoo ntawm lub tshuab nqus tsev, uas tau nruab rau hauv lub casing thiab ua rau hauv daim ntawv faus ncaj qha. Tsis tas yuav teeb tsa kev soj ntsuam zoo. Kev tsim kho kev lag luam yog yooj yim thiab lub sij hawm tsim kho yog luv. Nws yog tsim rau conveying chav lossis lwm yam xov xwm hauv qab 2.5MPa thiab 350 ℃. Cov khoom siv steel yeeb nkab raws li txheej txheej tiv thaiv, uas muaj qhov zoo ntawm lub zog siab, tsis yooj yim rau kev puas tsuaj, kev tsim kho yooj yim thiab kev saib xyuas thiab kev pab lub neej ntev.
Yuav kom txo tau cov cua kub dissipation ntawm lub raj xa mus rau cov av, ib txheej thermal rwb thaiv tsev sib xyaw yog ntxiv rau sab nraud ntawm cov raj xa dej ntawm qhov nruab nrab thiab me me ntawm cov hluav taws xob hluav taws xob hluav taws xob los yog cov kav dej cua sov. Cov khoom siv thermal rwb thaiv tsev feem ntau yog nruj polyurethane ua npuas ncauj, thiab qhov kub ntawm 18 txog 120 degrees. Cov khoom no yog mos hauv kev ntxhib los mos. Txhawm rau txhim kho nws lub zog, txheej txheej polyethylene high-density txheej yog siv sab nraum lub thermal rwb thaiv tsev txheej los tsim cov khoom siv sib xyaw kom tiv thaiv cov dej hauv av los ntawm kev nkag mus rau hauv thermal rwb thaiv tsev txheej. Cov txheej txheem ua tiav ntawm cov khoom siv high-pressure polyurethane foaming yog siv los tua moj tej tawg xeb tshem tawm ntawm cov yeeb nkab steel thiab kho corona rau sab hauv ntawm cov yeeb nkab tiv thaiv sab hauv, txhawm rau txhim kho kev sib koom ua ke ntawm cov yeeb nkab thermal rwb thaiv tsev. Cov khoom siv insulating yog ib qho tawv polyurethane ua npuas ncauj nrog qhov ntom ntawm 60kg / m3 txog 80kg / m3. Qhov sib txawv ntawm cov yeeb nkab steel thiab lub casing yog puv puv thiab muaj qee qhov kev sib txuas, kom lub zog tag nrho tuaj yeem tsim los ntawm peb feem ntawm cov yeeb nkab steel, lub tes tsho sab nraud thiab cov txheej txheem rwb thaiv tsev. Polyurethane ua npuas ncauj muaj cov khoom siv zoo thiab thermal rwb thaiv tsev. Nyob rau hauv ib txwm muaj xwm txheej, nws tuaj yeem tiv taus qhov kub ntawm 120 degrees Celsius. Nws tuaj yeem tiv taus qhov kub ntawm 180 degrees los ntawm kev hloov kho lossis ua ke nrog lwm cov ntaub ntawv rwb thaiv tsev.
Prefabricated polyurethane insulated steel yeeb nkab yog muab faib ua peb txheej ntawm sab hauv mus rau sab nraud:
Thawj pem teb: ua haujlwm steel yeeb nkab pem teb
Raws li tus tsim thiab cov neeg yuav tsum tau muaj, seamless steel yeeb nkab, kauv steel yeeb nkab thiab ncaj seam steel yeeb nkab feem ntau xaiv. Tom qab steel yeeb nkab nto yog kho los ntawm kev txhaj tshuaj blasting qib siab, cov xeb tshem tawm qib ntawm cov yeeb nkab steel tuaj yeem ncav cuag SA2 hauv GB / t8923-1988 tus qauv, thiab cov nplaim roughness tuaj yeem ncav cuag r = 12.5 microns hauv gb6060.5-88 tus qauv.
Ob txheej: polyurethane rwb thaiv tsev txheej
Cov tawv polyurethane ua npuas ncauj yas yog txhaj rau hauv cov kab noj hniav uas tsim los ntawm cov yeeb nkab steel thiab sab nrauv los ntawm lub tshuab ua npuas siab, uas feem ntau hu ua "tube hauv raj foaming".
Peb txheej: high density polyethylene tiv thaiv txheej
Prefabricated rau hauv dub los yog daj polyethylene yas kav nrog ib tug tej phab ntsa thickness. Polyethylene tsis muaj ntxhiab, tsis muaj tshuaj lom thiab zoo li siv quav ciab. Nws muaj qhov kub thiab txias tsis kam. Qhov tsawg kawg nkaus kev pabcuam kub tuaj yeem ncav cuag - 70 ~ - 100 ℃. Nws muaj cov tshuaj lom neeg ruaj khov zoo, tuaj yeem tiv taus qhov yaig ntawm feem ntau cov kua qaub thiab cov hauv paus (tsis resistant rau acids nrog oxidizing zog), yog insoluble nyob rau hauv cov kuab tshuaj nyob rau hauv lub chav tsev kub, thiab muaj tsawg dej nqus. Txawm li cas los xij, vim tias nws yog cov kab hluav taws xob tawm, nws tuaj yeem maj mam yaj hauv qee cov kuab tshuaj organic tsis muaj qhov o, Zoo heev hluav taws xob rwb thaiv tsev. Nws txoj haujlwm yog los tiv thaiv polyurethane rwb thaiv tsev txheej los ntawm cov khoom tawv tawv, thiab lwm yam yog tiv thaiv corrosion thiab tsis muaj dej. High density polyethylene polyurethane ua npuas ncauj rwb thaiv tsev steel yeeb nkab yuav tsum ua raws li SY / t114-2000 thiab SY / t115-2001 cov qauv.
