Covtxias cia pipelineyog ib qho tseem ceeb ntawm kev cia txias txias, thiab kev siv lub hauv paus ntsiab lus ntawm nws cov rwb thaiv tsev kub thiab kev tiv thaiv kev tiv thaiv kom tsis txhob khov tuaj yeem txhim kho kev ua haujlwm ntawm qhov txias txias thiab txuag lub zog. Nov yog qee qhov kev tiv thaiv kev tiv thaiv thiab tiv thaiv Frost. Ua ntej tshaj plaws, kev ntsuas kub rwb thaiv tsev ntawm cov kav dej txias cia yog qhov tseem ceeb heev. Sab hauv qhov kub thiab txias ntawm qhov kev ua haujlwm ntawm qhov txias cia yog qhov tsawg, thiab qhov kub ntawm qhov chaw sab nraud yog siab. Yog tias qhov kev kho cua sov tsis tau ua tiav, cov cua kub tawm los ntawm cov raj xa dej yuav ua rau qhov kub thiab txias ntawm qhov chaw cia txias kom nce, ua rau cov khoom siv hluav taws xob thiab lub zog ntawm cov khoom siv txias. Yog li ntawd, cov kav dej txias cia yuav tsum tau insulated kom txo tau cov cua sov thiab txo lub zog poob.
Cov khoom siv rwb thaiv tsev feem ntau yog polyethylene ua npuas ncauj, fluorine yas, iav fiber ntau thiab lwm yam. Cov ntaub ntawv no muaj cov thermal conductivity tsawg thiab cov thermal rwb thaiv tsev zoo, uas tuaj yeem txo qhov kub hloov pauv ntawm cov kav dej. Lub rwb thaiv tsev tuaj yeem yog qhwv, qhov twg cov rwb thaiv tsev yog ncaj qha qhwv ib ncig ntawm cov yeeb nkab sab nraud, los yog laminated, qhov twg cov rwb thaiv tsev yog ntxiv ntawm sab hauv thiab sab nraud ntawm cov yeeb nkab. Qhov thib ob, kev ntsuas tiv thaiv kev tiv thaiv rau cov kav dej txias txias yog qhov tseem ceeb sib npaug. Nyob rau lub caij ntuj no, qhov kub qis yuav ua rau cov kav dej txias txias kom khov, cuam tshuam rau kev ua haujlwm zoo ntawm cov kav dej. Yog li ntawd, kev siv tshuaj tiv thaiv kev tiv thaiv yog qhov tseem ceeb tshwj xeeb.
Ib qho kev ntsuas los tiv thaiv khov yog rau nruabcua sov siv nyob rau hauv pipelines. Covyeeb nkab cua sov sivmuaj peev xwm tsim tau ib tug npaum li cas ntawm cov cua sov nyob rau sab nraum cov yeeb nkab los tiv thaiv nws los ntawm khov. Covdej pipeline cua sov sivtuaj yeem tswj tau kom qhib lossis kaw raws li qhov kub thiab txias hloov, txuag lub zog thaum ua kom cov dej ntws zoo ntawm cov kav dej. Tsis tas li ntawd, cov kav dej txias cia txias kuj yuav tsum tau ua kom muaj zog. Nyob rau lub caij ntuj no, cov dej hauv cov kav dej tuaj yeem ua rau khov los ntawm qhov kub thiab txias, ua rau cov dej khov uas txhaws cov kav dej thiab ua rau cov dej tsis zoo. Txhawm rau kom tsis txhob muaj qhov tshwm sim no, lub qhov dej ntws tau ua kom sov kom cov dej hauv cov dej ntws tawm hauv cov kua dej kom ntseeg tau tias cov dej ntws zoo.
Nyob rau hauv cov ntsiab lus, cov rwb thaiv tsev kub thiab tiv thaiv kev tiv thaiv kev ntsuas ntawm cov kav dej txias txias yog ib qho tseem ceeb txhais tau tias kom tswj tau qhov kev ua haujlwm ntawm qhov txias txias thiab txuag lub zog. Kev ntsuas hluav taws xob tsim nyog tuaj yeem txo lub zog poob thiab txhim kho kev ua haujlwm ntawm kev cia txias. Cov kev ntsuas tiv thaiv khov tuaj yeem tiv thaiv cov raj xa dej kom tsis txhob khov thiab ua kom lub cev ua haujlwm ntawm qhov txias txias. Hauv kev siv cov tswv yim, cov rwb thaiv tsev tsim nyog thiab kev tiv thaiv kev tiv thaiv yuav tsum raug xaiv raws li qhov xwm txheej tshwj xeeb ntawm cov kav dej txias txias kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm kev ua haujlwm txias txias.
