Expansion Joints yog dab tsi?
Expansion pob qij txha yog siv nyob rau hauv piping systems kom nqus thermal expansion los yog lub davhlau ya nyob twg txav qhov kev siv ntawm expansion loops yog undesirable los yog impractical.Expansion pob qij txha muaj nyob rau hauv ntau yam sib txawv thiab cov ntaub ntawv.

Txhua cov yeeb nkab txuas ob lub ntsiab lus yog raug rau ntau hom kev ua uas ua rau muaj kev ntxhov siab ntawm cov yeeb nkab.Qee qhov ua rau muaj kev ntxhov siab no
Sab hauv lossis sab nraud siab ntawm kev ua haujlwm kub.
Qhov hnyav ntawm cov yeeb nkab nws tus kheej thiab cov khoom txhawb nqa ntawm nws.
Kev txav mus los ntawm cov yeeb nkab seem los ntawm kev txwv sab nraud.

Thermal expansion
Hlau Expansion Joints tau nruab rau hauv cov yeeb nkab ua haujlwm thiab cov kav dej kom tiv thaiv kev puas tsuaj los ntawm kev loj hlob ntawm thermal, kev co, siab thrust thiab lwm yam khoom siv zog.Cov ntawv thov raug siv yog cov kav dej, cov khoom siv cua sov thiab cov kav dej hauv cov chaw nres tsheb fais fab thiab hauv kev lag luam tshuaj.Qhov no ua rau muaj kev xav tau ntau yam zoo uas ua raws li cov kev cai ntawm cov xov xwm tshwj xeeb.

Muaj ntau yam ntawm cov khoom siv hlau ua rau hauv ntau yam khoom siv.Cov kev xaiv muaj los ntawm qhov yooj yim tshaj plaws convoluted bellows siv hauv roj av refineries.
Cov ntaub ntawv suav nrog txhua hom stainless hlau thiab qib siab nickel alloy steels.
