Nyob rau hauv cov nqe lus ntawm daim ntawv thov scenarios, nws cov kev pab yog dav heev. Hauv kev tsim vaj tsev, nws feem ntau yog siv los ua cov khoom thauj -cov kab thiab cov ncej txhawb nqa rau cov chaw ntau pob loj thiab cov tsev siab siab - nce siab, hloov cov qauv steel ib txwm, uas tuaj yeem txo qhov hnyav tag nrho thiab txhim kho kev ruaj ntseg. Hauv choj thiab pawg hauv paus engineering, loj - txoj kab uas hla, tuab - cov kav dej LSAW steel yog cov tub ntxhais thauj khoom- cov kabmob; piv rau cov vaj tse pob zeb, lawv tsis tsuas yog sib zog, tab sis kuj tseem ua rau lub sijhawm tsim kho; Tsis tas li ntawd, kev txhawb nqa cua turbine ntauwd, cov hauv paus hauv paus dock, cov qauv steel loj hauv nroog, thiab cov khoom siv sab nrauv sab nrauv kuj tseem nyiam xaiv rau cov khoom siv yeeb nkab no.
Hais lus ncaj ncees, nws cov txheej txheem tsim khoom tsis yog qhov nyuaj, tab sis nws txoj kev ruaj ntseg yog siab heev. Cov txheej txheem tsim khoom siv ob txheej txheem ua ntej- vuam cov hauv paus hla thiab precision vuam cov khoom kawg. This ensures a stable and controllable welding process, resulting in a highly dense weld seam with virtually no common defects such as porosity or slag inclusions. Nyob rau tib lub sijhawm, cov khoom tiav ua tiav tag nrho cov tshuab txoj kab uas hla kev nthuav dav, zoo tso cov kev ntxhov siab sab hauv thiab txhawb nqa kev ntxhov siab ntau dua; Qhov no txhim kho kev tiv thaiv kev ntxhov siab thiab ua kom zoo dua qhov raug; Roundness, straightness, thiab phab ntsa thickness uniformity tag nrho ua tau raws li qhov yuav tsum tau ntawm siab -precision engineering installations, ua kom yooj yim ntawm - qhov chaw txuas thiab vuam, thiab txhim kho kev tsim kho kom zoo.
Hais txog kev ua tau zoo, cov yeeb nkab no tshwj xeeb yog qhov zoo tshaj plaws - haum rau hnyav - cov haujlwm ua haujlwm. Cov ntaub ntawv tseem ceeb muaj xws li Q235B thiab Q355B/C/D, muab lub zog nplua nuj gradient uas tso cai rau kev xaiv yooj yim raws li qhov project load-bearing peev, seismic resistance, thiab low-kub qhov kev pab cuam. Nws zoo heev plasticity, toughness, thiab txias dabtsi yog khoov kev ua tau zoo nyob rau hauv uniform load tis nyob rau hauv kev ntxhov siab, tiv thaiv lub zos kev nyuaj siab concentrations; Nws tsis kam mus deformation thiab siab tshaj qhov zoo tib yam welded kav. Qhov no yog vim li cas nws tsis yog ib qho yooj yim steel qauv khoom; nws kuj tseem tsim nyog rau ntau qhov hnyav sab nraum zoov, siab -qhov siab, thiab loj-span engineering ib puag ncig.
Kev thauj mus los thiab kev cia khoom kuj tseem ceeb heev. Vim muaj txoj kab uas hla loj thiab hnyav hnyav ntawm cov qauv LSAW steel kav, cov cuab yeej nqa khoom tsim nyog yuav tsum tau siv thaum hoisting kom tsis txhob muaj kev puas tsuaj rau cov yeeb nkab kawg. Qhov chaw cia yuav tsum tiaj tus thiab khov kho kom tsis txhob deformation tshwm sim los ntawm kev khaws cia ntev -. Tshwj xeeb tshaj yog thaum lub sijhawm thauj khoom hiav txwv, kev tiv thaiv xeb thiab kev ruaj ntseg yuav tsum tau coj los tiv thaiv cov teeb meem zoo thaum tuaj txog ntawm qhov chaw.
Ntawm no, nws yog ib qho tseem ceeb kom paub qhov txawv ntawm ib qho kev lag luam misconception: ntau tus neeg muas zaub tsis meej pem LSAW steel kav nrog pipeline LSAW steel kav. Cov qub ua raws li lub teb chaws cov qauv tshwj xeeb rau kev siv cov qauv, tsom rau lub zog, nruj, thiab ruaj khov, thiab tsim nyog rau kev thauj khoom zoo li qub-cov kabmob; qhov tom kawg yog feem ntau yog siv rau kev thauj mus los roj thiab roj, hais txog kev ua haujlwm siab, kev sib khi, thiab kev tiv thaiv corrosion los ntawm cov khoom thauj. Lawv cov kev siv thiab cov qauv ntsuas sib txawv kiag li, thiab lawv yuav tsum tsis txhob siv sib hloov thaum xaiv qhov project. Tsis tas li ntawd, piv rau cov kav dej welded, ncaj- seam submerged arc welded steel kav muaj luv luv weld txoj kev, ntau cov duab tsis tu ncua, thiab ruaj khov ntau yam kev ntxhov siab, ua rau lawv tsim nyog rau cov tub ntxhais load-cov kabmob uas tsis tshua muaj kev nyab xeeb thiab ruaj khov.
Zuag qhia tag nrho, cov qauv ncaj nraim- seam submerged arc welded steel kav tau dhau los ua cov khoom siv siab tshaj -cov khoom siv hauv kev tsim kho vaj tse, muab ob qho tib si tus nqi- kev ua tau zoo thiab kev nyab xeeb, ua tsaug rau lawv cov cuab yeej paub tab, kev ua haujlwm ruaj khov, thiab ntau yam ntawm cov xwm txheej siv tau. Nrog rau kev txhim kho txuas ntxiv ntawm cov loj- nplai infrastructure thiab cov haujlwm tshiab zog, daim ntawv thov scenarios ntawm cov yeeb nkab no txuas ntxiv nthuav dav, ua rau nws yog ib qho tseem ceeb welded yeeb nkab khoom uas tsis tshua muaj kev lees paub thiab kev ua tau zoo hauv steel qauv engineering.
