    Hydrostatic Kev Ntsuam Xyuas

    Nqe lus piav qhia 3

    Cov yeeb nkab yuav tsum tau txais kev kuaj hydrostatic yam tsis muaj kev lom los ntawm Weld Seam lossis Yeeb Nkab Lub Cev
    Cov tub ntxhais kawm tsis tas yuav muaj kev sim hydrostatically, muab cov feem ntawm cov yeeb nkab siv hauv kev khij cov pob qij txha ua ntej ua ntej kev koom ua haujlwm.

    Limer Kab

    Tracaulity:
    Rau PSL 1 Yeeb Nkab, cov chaw tsim tshuaj paus yuav tsum tsim thiab ua raws cov txheej txheem sau tseg rau kev saib xyuas:
    Cov kev kuaj kub kub kom txog thaum txhua qhov kev xeem chmical tau ua thiab ua raws nrog cov kev xav tau tshwj xeeb yog qhia
    Cov kev xeem-chav kuaj xyuas kom txog thaum txhua qhov kev ntsuas uas cuam tshuam nrog thiab ua haujlwm nrog cov kev cai tshwj xeeb yog qhia
    Rau psl 2 yeeb nkab, tsim cov chaw tsim tshuaj yuav tsim thiab ua raws cov txheej txheem sau tseg rau kev tswj hwm cov cua sov thiab cov xeem ntawv rau tus kheej rau cov yeeb nkab. Cov txheej txheem no yuav tsum muaj txoj kev tsim nyog rau tracing ib qho ntev ntawm cov yeeb nkab mus rau chav kuaj kom yog thiab cov tshuaj ntsuam xyuas kom raug.

    Ib qho ntawm qhov zoo ntawm SSAW cov yeeb nkab yog nws cov khoom lag luam tau yooj yim. Cov kav dej no tuaj yeem tsim nyob rau hauv ntau qhov ntau thiab tsawg cov diameters thiab thickinges thiab tuaj yeem kho kom tau raws li qhov haujlwm tshwj xeeb. Tsis tas li ntawd, kauv submerged arc welded kav welded feem ntau yog ua los ntawm cov hlau zoo, ua rau lawv kho kom haum thiab ua kom muaj kev pabcuam ntev dua.

    API 5L Kab Yeeb Nkab:

    API 5L Kab Yeeb NkabYog siv dav siv Hollow tshooj style cov yeeb nkab uas tau raws li cov koom haum Asmeskas roj av (API). Cov raj hluav taws xob no tsim rau cov kua dej thauj, xws li roj thiab nkev, dhau mus deb. API 5L Kab Kab yog paub rau nws lub zog siab, kav ntev thiab kev tawm tsam rau huab cua ib puag ncig.

    Cov txheej txheem tsim khoom ntawm Api 5L Kab Yeeb Cuam cuam tshuam nrog nruj zoo tswj kev ntsuas kom ntseeg tau tias nws txoj kev ntseeg tau. Cov kav dej no yog ua los ntawm cov roj carbon hlau thiab muaj cov khoom siv neeg kho kom zoo nkauj. Nruj nreem rau API cov qauv ua kom cov kav dej uas cov kav dej siab tuaj yeem tiv thaiv qhov siab thiab kub hloov pauv, kev lag luam roj ntsha.

    Ua ke zoo:

    Thaum kauv submerged arc welded yeeb nkab thiab api 5L kab yeeb yog sib xyaw, lawv muab cov kev ntseeg ncaj ncees thiab kev ntseeg tau. Tus muab kauv seams ntawm ssaw yeeb nkab ua ke nrog lub zog thiab durability ntawm api 5L kab yeeb nkab tsim cov qauv kev txhawb zog muaj zog.

    Ntxiv rau lawv cov txiaj ntsig zoo, qhov sib piv ntawm kauv submerged arc welded yeeb nkab roj ua kom muaj kev ua tau zoo ntawm cov phiaj xwm pipeline. Cov versatility ntawm ssaw yeeb nkab tso cai yooj yim sib txuas nrog API 5L kab yeeb nkab, ua kom cov dej ntws tawm ntawm cov kua yeeb.

    Hauv kev xaus:

    Hollow ntu cov qauv kav dej yog qhov tseem ceeb tshaj plaws thaum lub tsev muaj cov cuab yeej muaj zog. Kev sib xyaw ua ke ntawm SSAW cov yeeb nkab thiab API 5L kab yeeb nkab muab cov tshuaj muaj zog uas muab zog, kav ntev thiab kev ntseeg tau rau ntau yam haujlwm. Txawm hais tias kev txhawb nqa lub hauv paus ntawm cov vaj tse siab lossis thauj cov dej tseem ceeb tshaj, cov kav dej ua si lub luag haujlwm ntev thiab ruaj khov ntawm peb cov cuab yeej siv hluav taws xob. Los ntawm kev siv zog ntawm kev kauv submerged arc welded yeeb nkab welded ntawm api 5L kab yeeb nkab, engineers tuaj yeem tsim lub hauv paus rau ib qho zoo dua tag kis.
