Dab tsi yog qhov ua txhaum ntawm cov hlab ntsha siab?

I. Kev tawg

Kev tshwm sim: Cov kab nrib pleb tshwm nyob rau hauv lub nkoj phab ntsa los yog qhov chaw weld, uas yuav ua rau nkig tawg, qaug zog tawg, los yog corrosion cracking.

Ua rau: Kev tsim khoom tsis raug, kev ntxhov siab thaum siv, lossis cov xov xwm corrosive.

Kev Kho Mob: Cov kab nrib pleb raug kuaj pom los ntawm kev tshuaj xyuas qhov muag thiab tsis yog- kuaj kev puas tsuaj (xws li kev ntsuas nkag mus thiab kuaj cov khoom sib nqus). Cov mob hnyav yuav tsum tau hloov cov khoom siv.

II. Corrosion

Kev tshwm sim: Corrosion tshwm sim nyob rau sab hauv thiab sab nrauv ntawm lub nkoj vim muaj tshuaj lom neeg lossis cov tshuaj electrochemical, xws li corrosion tsis zoo, pitting corrosion, thiab intergranular corrosion.

Ua rau: Media corrosion, tsis ua hauj lwm ntawm kev tiv thaiv -corrosion ntsuas, los yog deterioration ntawm txheej txheem tej yam kev mob.

Kev kho mob: me me corrosion tuaj yeem saib xyuas thaum siv; corrosion hnyav yuav tsum tau txo qis los yog hloov cov khoom siv.

III. Deformation

Manifestations: Localized dents, bulges, los yog tag nrho expansion ntawm lub nkoj.

Ua rau: Siab dhau, kev ua haujlwm tsis zoo, lossis kev ua haujlwm ntawm qhov kub thiab txias.

Kev kho mob: me me deformation tuaj yeem saib xyuas; deformation hnyav yuav tsum tau soj ntsuam kev tshaj lij.

IV. Safety Accessory Malfunction

Pressure Gauge: Kev nyeem ntawv tsis raug lossis thaiv lub siab kais.

Kev Nyab Xeeb Valve: Tawg, nquag mus, lossis tsis ua haujlwm.

Theem Gauge: Kev nyeem ntawv qib tsis raug lossis kev sib kis tsis zoo.

Kev tuav: tsis tu ncua calibration; hloov tam sim yog tias txawv txav.

V. Leakage

Cov tsos mob: Cov pa nruab nrab los ntawm qhov chaw sib khi los yog cov kab nrib pleb hauv cov hlab ntsha.

Ua rau: foob tsis ua hauj lwm, corrosion perforation, los yog bulging / deformation.

Kev tuav: Tam sim ntawd nres, tshuaj xyuas thiab hloov cov khoom puas.

VI. Tshaj siab

Cov tsos mob: Siab tshaj qhov tso cai.

Ua rau: Kev ua haujlwm yuam kev, kev ruaj ntseg accessory malfunction, los yog txheej txheem txawv txav.

Kev tuav: Tam sim ntawd txo qhov siab thiab ceeb toom rau cov chaw haujlwm cuam tshuam los tshawb xyuas qhov ua rau.

VII. Kev tawg

Cov tsos mob: Cov thawv ntim khoom tawg ua rau tawg.

Ua rau: Kev kub siab dhau, kev sib xyaw nruab nrab, lossis kev ruaj ntseg accessory malfunction.

Kev tuav: Kev khiav tawm tam sim ntawd thiab ua kom cov phiaj xwm teb xwm ceev.
