Qhov zoo ntawm kauv submined arc welded yeeb nkab:

1. Siv txuag tau:

SSAW cov pipes ib kauv weld tsim qauv uas tso cai rau kev tsim cov khoom lag luam zoo thiab txo qis. Qhov no cov xeeb ceem tshwj xeeb no ua rau nws xaiv thawj qhov kev xaiv rau kev tsim qauv loj xws li roj thiabRoj Kav, Dej kis dej tshuab, thiab ntug dej drilling platform. Cov txheej txheem txuas ntxiv vuam ua kom muaj kev ntseeg siab ntawm cov txheej txheem kev ncaj ncees, nce lub durability thiab kev pabcuam lub neej ntawm cov yeeb nkab.

2. Lub zog zoo thiab hloov tau zoo:

Tus qauv coj ntawm ssaw cov yeeb nkab nce ntxiv rau nws lub zog, tso cai rau nws tiv thaiv sab nraud thiab sab hauv. Cov kav dej no muaj peev xwm tiv taus cov cua hauv huab cua huab, ua rau lawv haum rau saum toj no thiab hauv qab cov ntawv thov. Tsis tas li ntawd, qhov yooj ntawm cov SSAW cov kav dej tso cai rau lawv kom yooj yim yoog thiab nruab rau ntau hom terrains, suav nrog cov av ntxhib thiab tsis khov khov.

3. Cov tshuaj zoo:

Nruam vuam cov txheej txheem nce cov khoom lag luam thaum muaj kev cuam tshuam vuam tsis xws luag thiab cov nqi. Tsis tas li ntawd, kauv submerged arc welded kav kev muab lub zog zoo dua thiab kev kho cov nqi thiab kev xaiv kev lag luam rau kev lag luam.

Cov kev sib tw uas muaj los ntawm kauv submerged arc welded kav dej:

1. Tswjhwm Zoo:

Vim hais tias ntawm cov txheej txheem vuam complex uas tsim cov kauv submerged arc welded kav, ua kom zoo sib xws yog qhov nyuaj. Yog tias vuam qhov tsis yog tswj kom raug, vuam tsis xws li undercuts, pores, thiab tsis muaj fusion yuav tshwm sim. Yuav kom kov yeej qhov kev sib tw no, nruj kev tswj kev ntsuas thiab kev saib xyuas kev tshawb xyuas kev tsim khoom yog qhov tseem ceeb.

2. Yeeb nkab hla kev txwv ntau yam:

Thaum muab kauv submerged arc welded kav yog qhov zoo tagnrho rau kev lag luam streger loj, lawv yuav tsis haum rau kev lag luam uas xav tau cov yeeb nkab tsawg. Cov txheej txheem tsim tau yog ntau dua rau cov kav dej loj, ua rau muaj kev txwv me me rau cov phiaj xwm me me xws li cov piping thiab cov khoom lag luam me me. Rau cov cai no yuav tsum muaj, lwm yam yeeb nkab raug yees siv tshuab yuav tsum tau txiav txim siab.

3. Cov txheej saum npoo:

Lwm qhov kev sib tw ntsib SSAW cov yeeb nkab kev lag luam yog kom tsim nyog thiab ua kom muaj zog rau kev tiv thaiv corrosion thiab hnav. Cov ntawv thov txheej ntawm cov kauv yuav tsum muaj cov cuab yeej zoo thiab cov kev txawj ntse kom ntseeg tau tias tseem muaj kev pov hwm thiab cov nplaum. Tsim kom zoo txheej txheem yog qhov tseem ceeb kom ncua kev pabcuam lub neej ntawm kev kauv submerged arc Welded yeeb nkab, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig hnyav.

Hauv kev xaus:

Muab kauv submerged arc welded kav welded tau ua pov thawj rau kev ua tau zoo heev hauv kev lag luam niaj hnub, muaj zog thiab nqi-ua hauj lwm. Nws cov kab ke ntawm cov kauv weld tso cai rau kev tsim khoom zoo thiab muaj zog nce ntxiv, ua kom haum rau cov haujlwm tsim kev tsim kho loj. Txawm li cas los xij, rau kev ua tiav txuas ntxiv thiab muaj ntau txoj kev xa khoom siv ntawm cov tshuab raug no, cov kev tswj hwm xws li kev tswj hwm zoo, thiab cov txheej txheem degree yuav tsum raug hais. Los ntawm kev kov yeej cov kev sib tw no los ntawm kev ua haujlwm thev naus laus zis thiab kev sib koom tes kev lag luam muaj cov khoom siv hluav taws xob welded muaj kev hloov pauv thiab txhawb nqa cov cuab yeej tseem ceeb hauv ntiaj teb.
