Roj Hmab Expansion Joint yog ib qho siv cov yeeb nkab txuas, feem ntau yog siv los txuas cov kav dej ntawm cov khoom sib txawv, txoj kab uas hla, lossis cov duab. Nws yog tsim los ntawm cov khoom siv roj hmab thiab hlau, nrog rau kev ua haujlwm zoo corrosion, kub tsis kam, thiab siab tsis kam.
Thaum siv cov roj hmab flanged, cov ntsiab lus hauv qab no yuav tsum raug sau tseg:
1. Ua ntej kev teeb tsa, cov tsos thiab qhov loj ntawm qhov sib koom yuav tsum tau kuaj xyuas kom ntseeg tau tias nws ua tau raws li qhov yuav tsum tau ua thiab tsis puas lossis deformed.
2.Ua ntej kev teeb tsa, lub flange nto ntawm ob qhov kawg ntawm lub raj xa dej yuav tsum tau muab ntxuav kom huv si kom ntseeg tau tias cov pob qij txha tuaj yeem haum nruj.
3. Thaum lub sij hawm installation, cov roj hmab ib feem ntawm qhov sib koom yuav tsum tau muab tso rau ntawm qhov chaw flange ntawm ob qho kawg ntawm cov kav dej, thiab tom qab ntawd cov kev sib koom ua ke yuav tsum tau kho ntawm lub raj xa dej nrog bolts.
4.Thaum zawm bolts, lawv yuav tsum tau nruj raws li tus nqi torque teev kom ntseeg tau tias kev sib khi ua haujlwm ntawm kev sib koom ua ke.
5.Thaum siv, kev sib khi ua haujlwm ntawm kev sib koom tes yuav tsum tau kuaj xyuas tsis tu ncua. Yog tias pom muaj dej ntws los yog xoob, nws yuav tsum tau kho lossis hloov raws sijhawm.
Nyob rau hauv luv luv, flanged roj hmab pob qij txha yog ib qho tseem ceeb pipeline connectors, thiab kev siv thiab tu kom zoo tuaj yeem ua kom muaj kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov kav dej.
