1. Ua ntej-Kev Npaj Kev Txhim Kho thiab Kev Tsim Qauv
Kev txhim kho zoo ntawm stainless hlau yeeb nkab fittings pib nrog cov ncauj lus kom ntxaws txheej txheem tsim thiab ua ntej - kev npaj kev teeb tsa uas suav nrog cov kev xav tau ntws, kev ntsuas siab, ntsuas kub hloov pauv, thiab kev saib xyuas yooj yim. Kev xaiv cov khoom tsim nyog suav nrog kev ntsuas qhov sib xws ntawm cov qib haum thiab cov khoom xa tawm kom ntseeg tau tias muaj kev tiv thaiv corrosion txaus thiab lub zog siv tshuab raws li cov kev pabcuam tshwj xeeb. Cov txheej txheem txheej txheem tseem yuav tsum xav txog kev nthuav dav thermal thiab kev cog lus, koom nrog kev nthuav dav pob qij txha lossis cov khoom sib txuas yooj yim uas tsim nyog los tiv thaiv kev ntxhov siab- ua rau tsis ua tiav. Kev txhawb nqa kom raug qhov sib nrug thiab cov yeeb nkab routing txo qhov kev ntxhov siab ntawm cov fittings thaum muab kev yooj yim rau kev tshuaj xyuas thiab tu. Thaum lub sij hawm tsim qauv, kev tswj xyuas kev ua tau zoo- suav nrog kev txheeb xyuas cov ntaub ntawv pov thawj, qhov tseeb qhov tseeb, thiab cov kev ntsuas siab siab- yuav tsum tau ua kom ntseeg tau tias ua tau raws li qhov project specifications.
2. Cov txheej txheem vuam thiab kev ruaj ntseg zoo
Vuam stainless hlau yeeb nkab fittings xav tau cov tswv yim tshwj xeeb los tswj cov corrosion kuj thiab txhua yam kev ncaj ncees ntawm cov ntaub ntawv hauv paus. Kev npaj sib koom ua ke yuav tsum tau ua kom huv si kom tshem tawm cov kab mob, roj, thiab oxide txheej uas tuaj yeem cuam tshuam qhov zoo ntawm vuam. Gas Tungsten Arc Vuam (GTAW/TIG) yog qhov zoo dua rau cov ntawv thov tseem ceeb, muab kev tswj xyuas qhov kub thiab txias zoo nrog cov cua sov tsawg heev - thaj chaw cuam tshuam. Rov qab-purging nrog cov roj inert tiv thaiv oxidation thiab paug ntawm cov hauv paus hniav, ua kom muaj kev tiv thaiv corrosion thoob plaws hauv kev sib koom tes. Tom qab-welding tu thiab passivation rov qab tiv thaiv oxide txheej tseem ceeb rau stainless hlau corrosion kuj, thaum uas tsis yog -kev kuaj kev puas tsuaj (NDT) txheeb xyuas qhov kev ntseeg ntawm vuam thiab ua raws li cov cai thiab cov qauv.
3. Kev Ntsuas thiab Kev Ua Haujlwm
Kev soj ntsuam zoo thiab cov txheej txheem ua haujlwm tau lees paub tias cov khoom siv stainless hlau cov yeeb nkab fittings ua tau zoo thiab ua tau raws li cov qauv kev nyab xeeb thiab kev tswj hwm. Hydrostatic kev ntsuas siab validates kev sib koom ua ke thiab xyuas kom meej tias qhov kev ntsuas siab ua tau raws li lossis tshaj qhov tsim nyog. Kev kuaj xyuas cov dej xau kom ntseeg tau tias tsis muaj cov pa tawm uas tuaj yeem ua rau muaj kev nyab xeeb ntawm kev ua haujlwm lossis kev ua raws li ib puag ncig. Flow testing paub meej tias kev ua haujlwm hydraulic thiab txheeb xyuas cov kev txwv lossis qhov tsis sib xws uas cuam tshuam rau kev ua haujlwm ntawm lub cev. Ua kom tiav cov ntaub ntawv- suav nrog cov ntawv xeem, daim ntawv pov thawj cov ntaub ntawv, thiab cov ntaub ntawv teeb tsa- muab qhov tseem ceeb ntawm kev taug qab thiab txhawb nqa kev tu thiab ua raws li kev ua haujlwm thoob plaws hauv lub neej ua haujlwm.
