Vim li cas dej tank tshuaj xyuas ua ntej ua zaub mov xa tuaj?
1. Tiv thaiv cov kev tsis txaus siab loj uas tshwm sim los ntawm cov dej xau. Kev vuam tsis zoo lossis kev sib koom ua ke tuaj yeem ua rau pom kev tom qab kev teeb tsa. Cov dej xau tuaj yeem ua rau cov chaw nyob ntawm qhov chaw puas. Kev xa rov qab cov khoom tom qab tuaj txog txawv teb chaws yuav ua rau tus nqi loj ntxiv.
2. Zam kev sib dhos tsis sib haum. Kev sib txawv ntawm tag nrho qhov loj me lossis qhov chaw yuav txwv cov neeg siv khoom los ntawm kev txhim kho cov tso tsheb hlau luam ib txwm, uas ua rau ncua kev ua haujlwm thiab ua rau muaj kev sib cav txog kev lag luam.
3. Nrhiav cov khoom siv thiab kev ua haujlwm txaus ntshai ua ntej. Sub-standard phaj thickness, tsis zoo los tiv thaiv corrosion txheej thiab ntxhib vuam yuav ua rau lub neej luv luv. Kev tshuaj xyuas pab tsis lees paub ntau yam ua ntej ua zaub mov xa tuaj.
4. Kev thauj mus los tsawg dua kev pheej hmoo. Kev thauj mus los hauv hiav txwv ntxhib tuaj yeem ua rau lub cev tank. Peb tuaj yeem txhim kho kev tiv thaiv ntim khoom thaum kuaj xyuas ua ntej xa khoom.
5. Ua kom cov khoom seem thiab cov khoom siv ua tiav. Tsis muaj gaskets lossis fasteners yuav tuav cov neeg siv khoom ntawm qhov chaw ua haujlwm.
Kev soj ntsuam Standards
Kev Cai Sampling
Sampling yog ua raws li AQL cov qauv, nrog rau cov qauv xaiv los ntawm cov khoom tiav batch tos cov khoom xa tuaj. Kev nyab xeeb-cov teeb meem cuam tshuam thiab dej siab / dej tsis ua haujlwm tau raug cais raws li ** Tsis Txaus Siab Tseem Ceeb (CR=0)**; nrhiav pom ntawm tej yam tsis xws luag yuav tsis lees paub tag nrho cov batch.
Kev soj ntsuam cov khoom thiab kev lees txais
1. Cov ntaub ntawv thiab Specification Verification
Txheeb xyuas qhov kev txiav txim yuav khoom, kos duab, qauv, thiab cov ntaub ntawv npe. Cov khoom tshwj xeeb thiab qhov chaw ua haujlwm yuav tsum ua raws li cov neeg siv khoom kos duab. Cov ntawv sau npe yuav tsum ua kom tiav thiab pom tseeb.
2. Kev tshuaj xyuas qhov muag
Lub tank saum npoo yuav tsum tsis muaj qhov pom tseeb dents thiab kua muag. Cov tshuaj tiv thaiv -corrosion txheej yuav tsum zoo ib yam, tsis muaj tev, flaking, lossis khawb hnyav. Weld seams yuav tsum du, tsis muaj porosity, txias welds, los yog tawg. Yuav tsum tsis muaj burrs ntse ntawm cov npoo.
- Tseem ceeb: Weld tawg, tank tsim kua muag, los yog perforation
- Loj: Loj: - thaj tsam txheej txheej txheej, loj dent deformation, txias vuam
- Me: Teeb khawb, me me -weld blemishes
3. Dimensional soj ntsuam
Ntsuas tag nrho qhov ntev, dav, qhov siab, phaj thickness, flange qhov ntev, thiab qhov nruab nrab qhov nrug. Ntsuas qhov tseem ceeb yuav tsum nyob twj ywm hauv kev kos duab tolerances. Tawm ntawm - ntawm - kev ntsuas kev ua siab ntev suav tias yog qhov tsis xws luag loj; cov khoom uas tsis tuaj yeem sib dhos ua rau batch rejection.
4. Sealing thiab Hydrostatic Test (Ua raws li tus neeg thov)
Ua hydrostatic lossis dej - sau cov dej xau raws li cov neeg siv khoom xav tau. Tsis pub dej los yog poob rau ntawm lub tank lub cev, welds, lossis flange pob qij txha thaum nyob hauv siab. Txhua qhov dej xau raug cais raws li qhov tsis xws luag.
5. Kev tshuaj xyuas khoom siv
Accessories-xws li flanges, gaskets, thiab fasteners- yuav tsum yog hom raug, ua kom muaj nuj nqis, thiab tsis muaj xeb lossis tawg. Cov khoom siv uas ploj lawm lossis tsis raug suav tias yog qhov tsis xws luag.
6. Ntim thiab Sau npe
Lub ntim sab nrauv yuav tsum ruaj khov thiab muab cov dej noo- pov thawj thiab cuam tshuam- tiv thaiv tiv thaiv. Cov cim kev xa khoom thiab cov qauv ntawv yuav tsum tau luam tawm thiab pom tseeb. Ntim kev puas tsuaj uas tuaj yeem ua rau kev thauj mus los tau raug cais raws li qhov me lossis loj, nyob ntawm qhov loj ntawm kev puas tsuaj.
Kev txiav txim siab
Cov batch raug lees txais yog tias qhov teeb meem tseem ceeb=0, qhov tsis xws luag loj tsawg dua lossis sib npaug rau 2.5 AQL, thiab qhov tsis zoo me me Tsawg dua lossis sib npaug rau 4.0 AQL. Yog tias cov kev txwv no dhau lawm, tag nrho cov khoom lag luam tsis raug tshuaj xyuas, thiab lub Hoobkas yuav tsum rov ua haujlwm dua thiab rov ua dua - tshuaj xyuas cov khoom.
