Kev tsim cov hlau nplaum hnub los ntawm 1800's. Thaum pib, yeeb nkab tau tsim los ntawm tes - los ntawm cov cua sov, khoov, lapping, thiab rauj cov npoo ua ke. Thawj cov kev siv yeeb nkab cov yeeb nkab tsim tau qhia hauv 1812 hauv tebchaws Askiv. Cov txheej txheem tsim khoom tau txuas ntxiv hloov txij li lub sijhawm ntawd. Qee cov yeeb nkab nrov sib xyaw ua ke tau piav qhia hauv qab no.
Lap Vuam
Kev siv Lap vuam los tsim cov yeeb nkab tau qhia nyob rau thaum ntxov xyoo 1920. Txawm hais tias txoj kev tsis ua haujlwm, qee cov yeeb nkab uas tau tsim los siv Lap Vuam cov txheej txheem tseem siv hnub no.
Nyob rau hauv txoj cai lap vuam txheej txheem, hlau tau rhuab nyob rau hauv lub cub tawg thiab tom qab ntawd dov mus rau hauv cov duab ntawm lub tog raj kheej. Cov npoo ntawm cov phaj steel tau tom qab ntawd "txoj phuam qhwv caj dab". Txoj phuam qhwv cajd cuam tshuam nrog overlaying sab hauv ntawm cov hlau phaj, thiab lub tapered ntug ntawm sab nraud ntawm lub phaj. Lub npoo yog ces welded siv lub pob vuam, thiab cov yeeb nkab rhuab tau dhau los ntawm cov txiv ntoo uas yuam cov leeg ua ke los tsim ib daim ntawv cog lus.
Cov velds tsim los ntawm Lap Vuam tsis yog raws li cov neeg tsim siv cov txheej txheem niaj hnub ntxiv. Cov neeg Asmeskas haiv neeg ntawm cov neeg kho tshuab engineers (ASME) tau tsim ib qho kev sib npaug rau kev suav cov yeeb nkab uas tau tso cai ntawm cov yeeb nkab, raws li hom txheej txheem tsim khoom. Qhov kev sib npaug no suav nrog cov ntsiab lus sib txawv raws li "sib koom ua ke", uas yog raws li hom kev siv Weld siv los tsim cov leeg ntawm cov yeeb nkab ntawm cov yeeb nkab ntawm cov yeeb nkab ntawm cov yeeb nkab ntawm cov yeeb nkab ntawm cov yeeb nkab ntawm cov yeeb nkab Seamless kav muaj ib qho kev sib koom tes ntawm 1.0 Lap Welded yeeb nkab muaj qhov sib koom ua ke ntawm 0.6.
Hluav taws xob tiv thaiv welded yeeb nkab
Hluav taws xob tsis welded (ERW) yeeb nkab yog tsim los ntawm cov ntawv txias txias rau ib daim hlau uas ua rau hauv ib lub cylindrical puab. Tam sim no yog tom qab ntawd dhau ntawm ob lub npoo ntawm cov hlau los ua kom sov cov hlau mus rau ib qho npoo yog yuam ua ke yam tsis muaj kev siv vuam cov khoom siv. Pib cov txheej txheem tsim kev tsim qauv no siv tsawg zaus AC tam sim no los ua kom sov cov npoo. Qhov txheej txheem qis no tau siv los ntawm xyoo 1920 txog xyoo 1970, tsawg kawg cov txheej txheem tau hloov cov txheej txheem loj uas tau ua rau muaj weld siab dua.
Sij hawm dhau los, cov ntsiav tshuaj ntawm tsawg zaus ERW cov yeeb nkab tau pom tias yog cov leeg uas muaj peev xwm xaiv tau cov nqaws, yog li tsawg zaus ERW tsis siv los tsim cov yeeb nkab. Cov txheej txheem siab tshaj plaws tseem siv los tsim cov yeeb nkab rau siv hauv kev tsim kho tshiab tshiab.
FAIS FAJ YAS WELDED YEEB NKAB
Fais Ntsa Welded Yeeb Nkab tau pib pib xyoo 1927. Flash Vuam tau ua tiav los ntawm kev sib sau cov ntawv hlau mus rau hauv cov ntawv cylindrical. Cov npoo tau ua kom sov kom txog thaum semi-molten, tom qab ntawd yuam ua ke kom txog thaum Molten hlau raug yuam tawm ntawm cov sib koom tes thiab tsim cov hlaws dai. Zoo li tsawg zaus ERW cov yeeb nkab, cov nqaws ntawm Flash Welded cov yeeb nkab muaj kev cuam tshuam nrog corrosion thiab nuv tawg, tab sis kom tsawg dua li ERW cov yeeb nkab. Hom yeeb nkab no tseem muaj kev ua tsis tiav vim yog cov tawv me me hauv cov hlau phaj. Vim tias feem ntau ntawm Flash Welded yeeb nkab tau tsim los ntawm ib qho chaw tsim khoom, nws ntseeg tau cov pob zeb tawv no tau tshwm sim vim yog cov hlau tsim khoom siv los ntawm cov chaw tsim khoom tshwj xeeb. Nyem vuam yog tsis siv lawm los tsim cov yeeb nkab.
Ob chav submolled arc welded (dsaw) yeeb nkab
Zoo sib xws rau lwm cov yeeb nkab tsim cov txheej txheem, ua cov khoom siv ntawm ob tog arc Welded yeeb nkab cuam tshuam nrog thawj daim phiaj hlau ua ke. Cov npoo ntawm cov phaj dov yog tsim kom v-puab grooves yog tsim nyob rau sab hauv thiab sab nraud ntawm thaj chaw ntawm lub seam. Cov yeeb nkab leeg yog tom qab ntawd welded los ntawm ib qho dhau ntawm arc welder ntawm sab hauv thiab sab nraud submermed). Lub vuam arc yog subc nrog flux.
Qhov zoo dua ntawm cov txheej txheem no yog tias WELDS nkag 100% ntawm cov yeeb nkab phab ntsa thiab tsim cov khoom siv hluav taws xob muaj zog heev.
Seamless Yeeb Nkab
Seamless yeeb nkab tau tsim tawm txij li 1800's. Thaum cov txheej txheem tau hloov zuj zus, qee yam tseem ceeb tau txais tib yam. Seamless cov yeeb nkab yog tsim los ntawm tho qhov kub hloov cov hlau billet nrog lub mandrel. Lub hollowed steel yog ntau tshaj li yob thiab ncab kom ua tiav qhov xav tau ntev thiab lub taub. Lub ntsiab kom zoo ntawm seamless yeeb nkab yog qhov kev tshem tawm ntawm cov leeg-ntsig txog cov tsis taus; Txawm li cas los xij, tus nqi tsim khoom yog ntau dua.
Thaum ntxov seamless yeeb nkab tau raug rau qhov tsis xws luag tshwm sim los ntawm impurities nyob rau hauv cov hlau. Raws li cov qauv hlau ua kom zoo dua qub, cov kev tsis zoo no tau txo qis, tab sis lawv tsis tau raug tshem tawm tag nrho. Thaum nws zoo nkaus li tias cov yeeb nkab seamless yuav zoo rau tsim, cov yeeb nkab-welded, lub peev xwm los txhim kho cov yam ntxwv xav tau hauv cov yeeb nkab muaj tsawg. Vim li no, seamless yeeb yog tam sim no muaj nyob hauv cov qib qis thiab cov phab ntsa thicknesses dua li welded yeeb nkab.
Jindalai Steel Group tau tshwj xeeb hauv kev tsim cov qib siab ERW (hluav taws xob tiv thaiv welded) thiab swsaw (kauv subderged arc welded) kav. Peb lub tuam txhab tau nce qib φ610 mol heal-zaus ncaj seam tsis kam vuam tshuab, thiab φ3048m kauv submerged arc welded tshuab welded.
