RF hom Kev kub siab roj hmab expansion sib koom ua ke
Kev piav qhia
Lub luag haujlwm tseem ceeb ntawm ib qho flange expansion sib koom ua ke yog los tiv thaiv lub siab thiab thrust hauv cov kav dej.Kev them nyiaj cov kav dej vim thermal expansion thiab txias shrinkage tshwm sim los ntawm qhov loj me me hloov, uas yog them nyiaj pipeline axial displacement.Nyob rau tib lub sij hawm yooj yim mus cuag lub twj tso kua mis los yog valve installation, txij nkawm thiab disassembly.Yog hais tias lub siab ceev ntawm lub raj xa dej loj dhau los yog qhov kev hloov pauv ntau tshaj qhov muaj peev xwm nthuav dav ntawm nws tus kheej, lub raj xa dej ntawm cov khoom siv nthuav dav yuav tawg, ua rau muaj kev puas tsuaj rau cov twj sib txuas, li qub, thiab txawm tias tag nrho cov kav dej. .Yog vim li cas vim li cas cov pob qij txha nthuav dav tuaj yeem ua haujlwm hauv qhov chaw hnyav yog cov khoom siv thiab kev kho mob tshwj xeeb.
Ib qho flange expander feem ntau yog siv rau hauv kev hloov pauv thiab cua sov ntawm cov kav dej kom nqus tau kev co thiab txo cov suab nrov.Nws tuaj yeem ua qhov nqus nqus hauv txhua qhov kev qhia.Thaum txhim kho qhov nthuav dav, kho qhov ntev ntawm ob qhov kawg ntawm cov khoom lossis flange.Tusyees zawm lub caj pas txiv ntseej diagonally, thiab tom qab ntawd kho qhov txwv ceev, kom cov yeeb nkab tuaj yeem nthuav dav thiab sib cog lus nyob rau hauv qhov ntau ntawm expansion thiab contraction.Xauv tus nqi ntawm kev nthuav dav kom ntseeg tau tias kev ua haujlwm ntawm cov kav dej.
