Kev saib xyuas kom raug yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev pab lub neej ntawm forged flanges nyob rau hauv lub kav dej thaum lub sijhawm ua haujlwm ntev -.
Ua ntej, qhov xwm txheej ntawm kev sib txuas ntawm flange yuav tsum tau tshuaj xyuas tsis tu ncua, suav nrog kev nruj nruj, kev ruaj siab ntawm lub gasket, thiab qhov loj ntawm qhov chaw corrosion lossis hnav. Loose bolts los yog cov laus gaskets tau yooj yim ua rau xau; Yog li ntawd, tej yam txawv txav yuav tsum tau kho tam sim ntawd los ntawm kev zawm bolts los yog hloov gaskets.
Kev saib xyuas kuj yuav tsum tau them rau kev tiv thaiv nto thiab tiv thaiv - kev ntsuas corrosion. Rau forged steel flanges, tiv thaiv - xeb roj lossis cov txheej tiv thaiv yuav tsum khaws cia kom zoo. Kev tu kom tsis tu ncua kom tshem tawm cov xeb thiab cov deposits yog qhov tseem ceeb-tshwj xeeb tshaj yog nyob rau hauv cov huab cua ntub los yog corrosive ib puag ncig- los tiv thaiv hlau nto oxidation. Rau cov hlau tsis muaj steel lossis alloy steel flanges, kev tshuaj xyuas yuav tsum kuaj xyuas pitting lossis kev ntxhov siab corrosion tawg ntawm flange - mus rau - yeeb nkab interface, thiab kev tiv thaiv tsim nyog yuav tsum tau ua.
Cov txheej txheem tu yuav tsum tau suav nrog rau qhov cuam tshuam ntawm lub siab thiab qhov kub thiab txias ntawm cov flanges. Nyob rau hauv cov xwm txheej ntawm kev co txawv txav, cuam tshuam, los yog siab surges thaum lub sij hawm ua hauj lwm, lub flanges thiab lawv cov khoom sib txuas yuav tsum tau soj ntsuam tam sim ntawd rau qhov tsis sib xws kev ntxhov siab los yog deformation. Periodic non-kev kuaj kev puas tsuaj (NDT)-xws li kev kuaj ultrasonic lossis magnetic particle- ua kom pom ntxov ntawm cov kab nrib pleb thiab qhov tsis xws luag. Los ntawm kev saib xyuas zoo, forged flanges tuaj yeem tswj xyuas kev ruaj ntseg sealing, ruaj khov siab -cov kabmob muaj peev xwm, thiab kev nyab xeeb ua haujlwm nyob rau lub sijhawm ntev.
