Cov yeeb nkab hlau tsis muaj seamless feem ntau yuav tsum tau pleev xim thiab txiav ua ntej tawm hauv lub Hoobkas. Cov kauj ruam ua tiav no yog los txhim kho kev ua haujlwm ntawm cov yeeb nkab hlau thiab hloov kho rau ntau yam kev xav tau ntawm kev tsim kho.

Lub hom phiaj tseem ceeb ntawm kev pleev xim yog los tiv thaiv cov kav hlau kom tsis txhob xeb thiab lwj thaum lub sijhawm khaws cia thiab thauj mus los. Kev pleev xim tuaj yeem tsim ib daim zaj duab xis tiv thaiv rau ntawm qhov chaw ntawm cov kav hlau, cais cov huab cua thiab cov dej noo, thiab ua kom lub neej ua haujlwm ntawm cov kav hlau ntev dua. Kev pleev xim yog qhov tseem ceeb tshwj xeeb rau cov kav hlau uas yuav tsum tau khaws cia ntev lossis siv rau hauv qhov chaw noo noo.

Kev kho kom zoo nkauj yog los pab txhawb kev vuam cov kav hlau. Cov kav hlau tsis muaj qhov sib txuas feem ntau yuav tsum tau vuam thaum txuas. Bevel tuaj yeem ua rau thaj chaw vuam ntau dua thiab xyuas kom meej tias qhov vuam ruaj khov thiab kaw. Tshwj xeeb tshaj yog nyob rau hauv cov kav dej siv hauv qhov chaw siab thiab kub siab, kev kho kom zoo nkauj tuaj yeem txhim kho qhov zoo ntawm kev vuam thiab tiv thaiv kev xau thiab tawg.

Rau cov qauv tshwj xeeb ntawm cov kav hlau tsis muaj seamless, xws liASTM A106, ASME A53thiabAPI 5L, cov kev kho mob hauv qab no yuav tsum tau ua thaum lub sijhawm ua tiav:

Kev txiav: Txiav rau hauv qhov ntev uas xav tau raws li cov neeg siv khoom xav tau.
Kev pleev ximSiv cov xim tiv thaiv xeb rau ntawm qhov chaw ntawm cov yeeb nkab hlau.
BevelKev kho kom zoo nkauj yog ua raws li qhov xav tau, feem ntau suav nrog ib qho V-puab thiab ob chav V-puab bevels.
Kev ncaj: Xyuas kom meej tias cov yeeb nkab hlau ncaj rau kev teeb tsa thiab siv tau yooj yim.
Kev sim hydrostaticUa qhov kev sim hydrostatic ntawm cov yeeb nkab hlau kom paub tseeb tias nws tuaj yeem tiv taus qhov siab uas tau teev tseg thiab ua tau raws li cov qauv kev nyab xeeb.
Kev kuaj pom qhov tsis zooSiv cov txheej txheem kuaj tsis ua puas tsuaj xws li ultrasound thiab X-ray los xyuas qhov tsis zoo sab hauv ntawm cov yeeb nkab hlau kom paub tseeb tias nws zoo.
Kev cim: Kos cov lus qhia txog cov khoom, cov qauv, cov ntaub ntawv ntawm cov chaw tsim khoom, thiab lwm yam rau ntawm qhov chaw ntawm cov yeeb nkab hlau kom yooj yim nrhiav thiab tswj.
Cov kauj ruam ua tiav no ua kom ntseeg tau tias cov kav hlau tsis muaj qhov tsis sib xws thiab muaj kev nyab xeeb hauv ntau yam kev siv thiab ua tau raws li cov kev cai nruj ntawm cov kav hlau hauv ntau qhov chaw lag luam.
