Dab tsi yog qhov txawv ntawm seamless thiab welded yeeb nkab?
Cov kav dej ua ib feem tseem ceeb ntawm cov tshuab uas xav tau kev thauj mus los ntawm ntau yam xov xwm thoob plaws refineries lossis cov txheej txheem kev lag luam. Lub peev xwm ntawm cov khoom thiab cov xov xwm uas lawv thauj yuav nyob ntawm seb cov khoom uas lawv tau ua los ntawm. Qee yam ntawm cov khoom lag luam siv xws li PVC, stainless hlau, hlau alloy, carbon steel, nickel alloys, titanium alloys, tooj liab nickel, monel, Inconel, Hastelloy, thiab lwm yam. kuj coj mus rau hauv tus account thaum tsim lawv. Yeej, muaj ob hom kev siv yeeb nkab. Ua ntej yog hom seamless, uas tsis muaj seam, thiab lub voj voog ntawm cov yeeb nkab yuav tsis muaj pob qij txha. Yog li qhov saum npoo ntawm cov kav dej no yuav smoother thiab ntau dua. Qhov thib ob ntawm kev tsim kho yog hom welded. Tsis zoo li hom seamless, hom welded yuav muaj ib lub seam uas koom nrog cov yeeb nkab, uas ua rau muaj kev tsim cov seamline ntawm nws qhov chaw.
Hauv luv luv, qhov sib txawv tseem ceeb ntawm kev tsim kho ntawm ob lub kav dej no yog kev suav nrog cov seamline hauv kev tsim kho welded. Txawm li cas los xij, muaj qee qhov kev txwv uas cais ob qho kev tsim kho nrog rau lub peev xwm siab thiab tus nqi taw tes. Nyob rau hauv cov nqe lus ntawm lub siab bearing cuab yeej, kev siv ntawm ib tug seamless yeeb nkab enables siab dua bearing peev xwm. Qhov nruab nrab, lub siab los ntawm cov yeeb nkab seamless yog yuav luag 20% siab dua li cov khoom siv welded. Cov cuab yeej no ua rau nws muaj txiaj ntsig zoo rau tus neeg muag khoom siv hom seamless rau daim ntawv thov siab. Txawm hais tias kev siv cov yeeb nkab welded haum rau cov ntawv thov kev ntxhov siab, nws cov vuam seam ua rau nws yooj yim rau kev ua tsis tiav, tshwj xeeb tshaj yog tias cov cua sov cuam tshuam weld cheeb tsam yog cuam tshuam rau intergranular corrosion. Yog hais tias cov yeeb nkab tau corroded los ntawm sensitized grain ciam teb, muaj feem ntau ntawm cov yeeb nkab bursting ntawm seamline yog heev. Qhov no yog ib qho uas tsis xav tau, tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas thauj hla cov khoom siv tshuaj lom lossis cov khoom siv bio-tshuaj lom lossis txawm tias cov khoom siv hluav taws xob. Nyob rau hauv cov xwm txheej zoo li no, tus neeg muag khoom yuav xaiv siv cov yeeb nkab seamless vim tias lawv tsis muaj kev cuam tshuam rau intergranular corrosion thiab yog li, qhov yuav tshwm sim ntawm cov yeeb nkab tawg tau txo qis heev.
Nqe sib txawv ntawm seamless thiab welded yeeb nkab
Lwm thaj chaw uas cais cov yeeb nkab no yog lawv cov nqi sib txawv. Yog vim li cas rau qhov tshwm sim ntawm tus nqi sib txawv yog lawv cov txheej txheem tsim khoom. Txij li thaum lub welded yeeb nkab yuav siv los ntawm ib tug hlau phaj, nws yog ib tug kuj yig los tsim lawv. Tsis tas li ntawd, tus nqi ntawm kev tsim khoom kuj tseem nrawm dua, uas kuj yog ib qho tseem ceeb uas ua rau cov khoom lag luam raug nqi qis. Ntawm qhov tod tes, cov yeeb nkab seamless yog kos los ntawm billets, thiab cov txheej txheem tsim khoom siv zog heev thiab siv sijhawm. Cov yam ntxwv no ua rau tus nqi ntawm cov khoom siab dua thiab. Tsis tas li ntawd, lub siab muaj peev xwm ntawm cov kav dej seamless yog siab dua li cov welded, thiab qhov saum npoo yog ntau smoother, nrog rau qhov yuav txo tau ntawm corrosion. Kev sib xyaw ua ke ntawm tag nrho cov xwm txheej no ua rau cov khoom lag luam muaj txiaj ntsig zoo, tab sis kev xaiv kim dua hauv kev sib piv rau cov yeeb nkab welded.
Seamless thiab welded yeeb nkab raug txheej txheem
Raws li tau hais dhau los, welded kav yog tsim los ntawm cov ntawv hlau, nrog rau cov phab ntsa thickness hais los ntawm tus neeg yuav khoom. Qhov ntev ntawm daim ntawv ua ntej yuav tsum tau welded yuav tsum tau ua kom ob sab hauv thiab sab nraud txoj kab uas hla ntawm cov yeeb nkab. Cov qhov ntev no yuav tsum tau muab los ntawm tus neeg yuav khoom thaum xaj xaj. Txoj kev siv vuam siv, yuav tsum tau ua raws li cov txheej txheem ntau lawm. Feem ntau, cov chaw tsim khoom, cov chaw muag khoom, thiab cov neeg yuav khoom ua raws li ntau yam ntawm ASTM cov qauv uas ua raws li cov lus qhia thaum tsim khoom.
Kev tsim cov kav dej seamless ua rau siv cov kev kho cua sov. Lub alloy yog thawj rhuab, ua raws li los ntawm molding nrog kev siv ntawm ib tug khoom billet. Cov khoom billet yog dab tsi coj cov alloy mus rau hauv ib feem uas yog zoo li tus nyob rau hauv daim ntawv ntawm ib lub tog raj kheej. Thaum cov hlau ua cov thooj voos kheej kheej, lawv tau dov xws li lawv tau ncab thiab tsim hollows. Thaum lub sijhawm ua haujlwm no, qhov chaw hollowed ntawm lub tog raj kheej yog qhov tsis zoo. Yuav kom tau txais ib qho chaw sib luag, hollow center, ib lub mos txwv zoo li tus piercer point yog thrust los ntawm cov tub ntxhais ntawm lub billet, ib txhij, raws li lub tog raj kheej yog dov. Ua raws li cov txheej txheem no, cov kav dej tau muab tso rau hauv cov tshuab ntxiv uas ncaj nraim rau lawv, thaum tseem tshem tawm cov deformities los tsim, zoo dua, smoother, thiab ruaj seamless kav.
Seamless thiab welded yeeb nkab thov
Txij li thaum lub luag haujlwm tseem ceeb ntawm cov kav dej yog ferry hla cov ntaub ntawv, daim ntawv thov lossis kev siv qhov kawg ntawm cov khoom yuav yog nyob ntawm ntau yam nrog rau cov nqi, lub zog, hom xov xwm uas tau siv hauv daim ntawv thov, qhov tsis kam ntawm cov alloy rau corrosion hauv ntxiv rau qhov kub thiab txias qhov xav tau. Kev lag luam xws li tshuaj, tsev & kev tsim kho, kev ua zaub mov, kev lag luam dej haus, kev tsim hluav taws xob nuclear, thiab lwm yam, siv cov kav dej thauj mus los thoob plaws lawv cov khoom. Txawm li cas los xij, kev lag luam uas ua rau feem ntau ntawm cov khoom no yog kev lag luam petrochemical thiab natural gas.
