Seamless luj tshib: Luj tshib yog ib hom yeeb nkab fittings siv nyob rau hauv khoov ntawm cov yeeb nkab. Nyob rau hauv cov kav dej siv nyob rau hauv tag nrho cov yeeb nkab fittings, qhov loj tshaj plaws kev faib ua feem, txog 80%. Feem ntau, cov txheej txheem sib txawv yog xaiv rau lub luj tshib ntawm cov khoom sib txawv lossis phab ntsa thicknesses. Kev tsim cov nroj tsuag feem ntau siv seamless luj tshib txoj kev yog kub laub, stamping, extrusion, thiab lwm yam.
Kub thawb txoj kev
Kub laub lub luj tshib txoj kev tsim yog siv lub luj tshib tshwj xeeb thawb lub tshuab, cov tub ntxhais pwm thiab cov khoom siv cua sov, kom cov txheej txheem ntawm billet ntawm pwm nyob rau hauv lub tshuab thawb kom thawb rau pem hauv ntej lub zog, nyob rau hauv lub zog yog rhuab, nthuav thiab khoov rau hauv lub txheej txheem. Cov yam ntxwv deformation ntawm lub luj tshib kub yog raws li txoj cai ntawm yas deformation ntawm cov ntaub ntawv hlau ua ntej thiab tom qab lub ntim ntawm lub billet txoj kab uas hla, txoj kab uas hla ntawm lub billet siv yog tsawg tshaj li txoj kab uas hla ntawm lub luj tshib, los ntawm cov tub ntxhais pwm los tswj. cov txheej txheem deformation ntawm lub billet, kom lub puab arc ntawm compressed hlau ntws los them rau qhov nthuav thiab thinning ntawm lwm qhov chaw, thiaj li yuav tau ib tug uniform phab ntsa thickness ntawm lub luj tshib.
Kub laub lub luj tshib txoj kev tsim muaj ib tug zoo nkauj tsos, niaj hnub phab ntsa thickness thiab tas mus li kev lag luam, haum rau loj ntau lawm, yog li ua lub ntsiab txoj kev ntawm carbon steel, alloy steel luj tshib, thiab kuj siv nyob rau hauv lub tsim ntawm tej yam specifications stainless hlau luj tshib.
Kev tsim cov txheej txheem cua sov yog nruab nrab zaus los yog siab zaus induction cua sov (lub voj voog cua sov tuaj yeem ua ntau tig los yog tig ib zaug), nplaim hluav taws xob cua sov thiab qhov hluav taws xob hluav taws xob cua sov, kev siv cov cua sov txoj kev nyob ntawm qhov yuav tsum tau ua ntawm cov khoom tsim thiab lub zog qhov teeb meem. .
Stamping
Stamping txoj kev luj tshib yog qhov ntxov tshaj plaws siv nyob rau hauv lub loj zus tau tej cov seamless luj tshib txoj kev, nyob rau hauv zus tau tej cov feem ntau specifications luj tshib tau hloov los ntawm kub laub txoj kev los yog lwm yam txheej txheem, tab sis nyob rau hauv ib co specifications ntawm lub luj tshib vim yog zus tau tej cov me me. kom muaj nuj nqis, phab ntsa tuab tuab dhau los yog nyias dhau.
Cov khoom tseem siv tau thaum muaj cov kev cai tshwj xeeb. Lub luj tshib stamping thiab sib sau siv lub luj tshib sab nraud txoj kab uas hla sib npaug rau lub billet, kev siv cov presses hauv pwm ncaj qha nias rau hauv cov duab.
Ua ntej stamping, lub billet yog muab tso rau hauv qis tuag, lub puab tub ntxhais thiab qhov kawg tuag yog loaded rau hauv lub billet, thiab lub Upper tuag txav mus los pib nias, thiab lub luj tshib yog tsim los ntawm kev txwv ntawm lub sab nrauv tuag thiab kev txhawb nqa ntawm sab hauv tuag.
Piv nrog rau cov txheej txheem kub thawb, cov tsos ntawm stamping txoj kev zoo tsis zoo li qub; stamping luj tshib nyob rau hauv kev tsim ntawm lub sab nrauv arc nyob rau hauv ib tug tensile lub xeev, tsis muaj lwm yam seem ntawm cov hlau ntau dhau los them, yog li cov phab ntsa thickness ntawm lub sab arc yog hais txog 10% thinner. Tab sis vim yog cov yam ntxwv ntawm ib qho kev tsim khoom thiab tus nqi qis, yog li cov txheej txheem stamping luj tshib feem ntau yog siv me me, tuab-walled luj tshib raug tsim.
Stamped luj tshib yog muab faib ua ob hom txias stamping thiab kub stamping, feem ntau raws li cov khoom thiab cov khoom muaj peev xwm xaiv txias stamping los yog kub stamping.
Txias extrusion luj tshib txheej txheem yog kev siv lub luj tshib tshwj xeeb tsim tshuab, lub billet rau hauv cov txheej txheem tuag, lub sab sauv thiab qis tuag tom qab tuag, nyob rau hauv lub laub pas nrig, lub billet nyob rau hauv lub puab thiab txheej tuag reserved rau qhov sib txawv txav thiab ua tiav. txoj kev tsim.
Kev siv cov txheej txheem txias extrusion sab hauv thiab sab nraud tuag tsim lub luj tshib zoo nkauj zoo nkauj, cov phab ntsa tuab tuab, qhov sib txawv me me, yog li rau stainless hlau luj tshib, tshwj xeeb tshaj yog nyias-walled stainless hlau luj tshib tsim ntau dua li kev siv cov txheej txheem no. Cov txheej txheem no yuav tsum muaj qhov raug siab ntawm qhov tuag sab hauv thiab sab nraud; phab ntsa thickness sib txawv ntawm cov billet kuj tseem hnyav heev.
Phaj welding system
Siv lub phaj nrog xovxwm los ua ib nrab ntawm lub luj tshib profile, thiab tom qab ntawd txuas ob qhov profile ua ke. Cov txheej txheem no feem ntau yog siv los ua DN700 lossis ntau dua lub luj tshib.
Lwm txoj kev tsim
Ntxiv nrog rau cov txheej txheem saum toj no peb txoj kev tsim, seamless lub luj tshib tsim muaj kev siv extrusion ntawm billet rau sab nrauv tuag, thiab tom qab ntawd los ntawm cov pob zeb pob shaping txoj kev. Tab sis cov txheej txheem no yog qhov nyuaj, kev ua haujlwm teeb meem, thiab kev tsim cov khoom zoo tsis zoo li cov txheej txheem tau hais tseg, yog li siv tsawg dua.
Nws yog ib hom yeeb nkab haum feem ntau siv rau hauv kev teeb tsa cov kav dej los txuas ob lub kav dej ntawm tib lossis sib txawv nominal diameters, kom cov raj xa dej tuaj yeem ua rau lub kaum ntse ntse tig, thiab lub siab nominal yog 1-1.6Mpa.
Lub luj tshib los ntawm lub kaum sab xis, muaj 45 °, 90 °, 180 ° peb feem ntau siv, ntxiv rau, raws li kev xav tau ntawm engineering, kuj suav nrog 60 ° thiab lwm lub kaum sab xis tsis zoo; Raws li cov txheej txheem ntau lawm, tuaj yeem muab faib ua vuam luj tshib, stamping luj tshib, thawb lub luj tshib, casting luj tshib, thiab lwm yam.
1.Raws li feem ntau ntawm cov yeeb nkab fittings yog siv rau vuam, txhawm rau txhim kho qhov zoo ntawm vuam, qhov kawg yog tig mus rau hauv bevels, tawm hauv ib lub kaum ntse ntse nrog ib qho ntug, qhov kev xav tau no kuj tseem nruj, tuab npaum li cas ntawm ntug, lub kaum sab xis. rau ntau npaum li cas thiab qhov sib txawv ntawm qhov sib txawv tau teev tseg. Qhov saum npoo zoo thiab cov khoom siv kho tshuab yog qhov tseem ceeb tib yam li cov yeeb nkab. Rau qhov yooj yim ntawm vuam, steel hom yeeb nkab fittings thiab cov yeeb nkab txuas yog tib yam.
2.yog tias tag nrho cov yeeb nkab fittings tau raug kho rau saum npoo, sab hauv thiab sab nrauv ntawm cov hlau oxide los ntawm kev txhaj tshuaj blasting kev kho mob, thiab tom qab ntawd coated nrog cov xim tiv thaiv corrosion. Qhov no yog rau export xav tau kev pab, ntxiv rau, nyob rau hauv lub teb chaws kuj yog los pab txhawb kev thauj mus los los tiv thaiv xeb thiab oxidation, yog ua hauj lwm no.
3.yog qhov yuav tsum tau ntim rau cov yeeb nkab me me, xws li kev xa tawm, koj yuav tsum ua cov thawv ntoo, txog 1 cubic meters, tus naj npawb ntawm lub luj tshib hauv cov thawv no tsis tuaj yeem tshaj li ntawm ib tuj, tus qauv tso cai teev, uas yog, cov khoom loj. ntawm me me, tab sis qhov hnyav tag nrho feem ntau tsis tuaj yeem tshaj 1 tuj. Rau cov khoom loj ntawm y los ua ib pob, xws li 24 "yuav tsum yog ib pob. Lwm qhov yog lub cim ntim, lub cim yog qhia qhov loj, tus naj npawb steel, batch naj npawb, cov chaw tsim khoom lag luam, thiab lwm yam.
