Cov kav dej yog cov khoom siv "lifeline" rau kev tsim thiab tsim cov khoom siv roj thiab roj thiab cov khoom siv hauv av.Cov txheej txheem nruj nruj ntawm cov kav dej siv thev naus laus zis tau ua tiav, tab sis cov kev txwv hauv kev khoov, kev tiv thaiv corrosion, kev teeb tsa thiab kev tso nrawm tau nce nws cov nqi tag nrho.Cov xwm txheej hauv qab no tuaj yeem tshwm sim hauv kev siv cov kav dej tsis zoo:
Tsis muaj kev ywj pheej: Cov kav dej khov, vim lawv daim ntawv ruaj khov, tsis muaj peev xwm khoov lossis ncab, thiab yog li ua haujlwm tsis zoo hauv kev teb rau sab nraud xws li av hloov pauv, kub hloov, lossis av qeeg, tnws yuav ua rau cov yeeb nkab tawg los yog deform.
Susceptibility to stress concentration thiab qaug zog: Thaum cov kav dej tsis sib haum tau raug rau cov khoom siv sab nraud, qhov tsis muaj peev xwm nqus los yog cuam tshuam kev ntxhov siab tuaj yeem ua rau muaj kev ntxhov siab nyob hauvpaub tseebthaj chaw.Qhov no ua rau cov yeeb nkab muaj kev cuam tshuam rau kev qaug zog tsis ua haujlwm, tshwj xeeb tshaj yog tias nws nquag raug vibration lossis poob siab.
corrosion: Corrosion yog ib qho ua rau tsis ua haujlwm hauv pip nrujcov elines, tshwj xeeb tshaj yog metal cev.Sij hawm dhau mus, raug dej noo, tshuaj lom neeg thiab lwm yam corrosive tuaj yeem ua raucov kav dejua rau deteriorate, ua rau cov dej xau thiab cov qauv tsis muaj zog.
Raws li kev daws teeb meem tshiab, hloov taucov kav dejhaua vedaim ntawv thov tseem ceeb muaj nuj nqis hauv kev tsim khoom thiab kev loj hlob ntawm ntug dej hiav txwv roj thiab roj thiab cov peev txheej ntxhia.Nws zoo xws li bendability, anti-corrosion, installation thiab tso ceevtshem tawmcov kev txwv ntawm cov kav hlau ib txwm muaj, txo tus nqi tag nrho, thiab muab kev daws teeb meem zoo dua thiab txhim khu kev qha.Nrog kev txhim kho txuas ntxiv ntawm kev siv tshuab, hloov tau yooj yimcevs ua lub luag haujlwm tseem ceeb hauv kev lag luam kev lag luam tawm sab nraud.
Qhov zoo ntawm kev hloov pauv hoses:
●Raws li transported khoomflow, pibelinesystem yuav deformed thiab nthuav nyob rau hauv tus ntawm qhov kub thiab txias, siab thiab lwm yam.Yooj yimcov kav dejtuaj yeem them nyiaj rau cov deformations thiab thermal expansion los ntawm ncab, khoov, thiab lwm yam, thiaj li ua kom lub cev ua haujlwm ntawm pipelineqhov system.
● Flexiblecevtuaj yeem txo qhov kev vibration thiab suab nrov tsim los ntawm covkua dejnyob rau hauv cov yeeb nkab system, xyuas kom meejhauvkev ua haujlwm ib txwm ua ntawm cov yeeb nkab thiab cov khoom siv ntxiv.
● Flexiblehoss yogua los ntawm cov khoom hnav-resistant elastic, thiab covnpogntawm lub cevstuaj yeem tiv taus kub sab nraud,ntev UV raug, thiab txav mus los.
●Yooj yimcevs tau yooj yim txuas thiab distxuas, ua rau kev saib xyuas ntawm cov yeeb nkab system yooj yim dua thiab ua haujlwm zoo.Yooj yimcov kav dejhaua vesiab yooj thiab plasticity, thiab tuaj yeem hloov mus rau qhov kev sib txuas thiab kev saib xyuas cov kev xav tau ntawm ntau lub kav dej.
Saj zawg zog hose siv nyob rau hauv lub raj xa dej tuaj yeem txhim kho kev nyab xeeb, kev ruaj ntseg thiab kev ruaj ntseg ntawm cov kav dej, thiab yog ib feem tseem ceeb ntawm cov kav dej.
