Taw qhia txog txoj kev tsim cov luj tshib hauv cov yeeb nkab fittings
Taw qhia:
Lub luj tshib yog qhov tseem ceeb ntawm cov yeeb nkab fittings siv los hloov cov kev taw qhia ntawm cov kav dej. Lawv suav rau ib feem tseem ceeb ntawm tag nrho cov yeeb nkab fittings siv nyob rau hauv pipeline systems. Cov ntaub ntawv sib txawv lossis phab ntsa thicknesses yuav xav tau ntau yam txheej txheem rau lub luj tshib. Cov hau kev rau kev tsim cov luj tshib seamless muaj xws li mandrel dabtsi yog khoov, txias sib sau, thiab kub extrusion. Ntawm cov no, mandrel dabtsi yog khoov yog ib txoj hauv kev khoov lub luj tshib los ntawm kub extrusion. Txoj kev no muaj cov txheej txheem tsim khoom siab heev thiab feem ntau siv. Nyob rau hauv tsab xov xwm no, peb yuav qhia txog cov txheej txheem ntawm mandrel dabtsi yog khoov rau lub luj tshib, aiming los muab kev nkag siab zoo.
1. Txias Mandrel Bending:
Txias mandrel bending yog hais txog txoj kev khoov lub luj tshib ntawm qhov kub thiab txias ua haujlwm, qhov twg cov yeeb nkab steel yog khoov rau hauv chav tsev kub uas siv lub mandrel dabtsi yog khoov.
Txias mandrel dabtsi yog khoov cov cuab yeej muaj cov qauv yooj yim thiab tsis xav tau cov cuab yeej tshwj xeeb, ua rau lawv ua tau zoo heev. Txawm li cas los xij, cov phab ntsa tuab tuab (t / d Ntau dua lossis sib npaug rau 0.06) feem ntau yog xav tau rau cov kav hlau stainless. Txwv tsis pub, cov yeeb nkab dawb paug yuav poob stability vim tsis zoo rigidity, ua rau bending tsis ua hauj lwm. Txias mandrel dabtsi yog khoov yog haum rau lub luj tshib nrog me me cross-section (Less tshaj los yog sib npaug rau 3%-5%) thiab nyias phab ntsa (Less tshaj los yog sib npaug rau 9%) qhov twg lub vojvoog dabtsi yog khoov me me (r/ d ≈ 1.3). Khoov rau sab hauv yuav ua rau wrinkling los yog distortion.
2. Kub Mandrel Bending:
Nyob rau hauv sib piv rau txias mandrel dabtsi yog khoov, kub mandrel dabtsi yog khoov yog ib txoj kev khoov lub luj tshib nyob rau hauv high-temperature. Nws suav nrog thawb cov yeeb nkab los ntawm lub taub hau taub hau hauv qab axial thrust. Kev thawb ntawm cov yeeb nkab ua rau axial expansion thiab axial dabtsi yog khoov deformation ntawm cov yeeb nkab dawb paug, tso cai rau nws mus rau hauv lub luj tshib loj dua.
Txoj kab uas hla ntawm cov yeeb nkab dawb paug siv rau kub mandrel dabtsi yog khoov yog me dua li ntawm lub luj tshib. Cov txheej txheem deformation ntawm cov yeeb nkab dawb paug yog tswj los ntawm cov duab core pwm, tso cai rau lub puab arc hlau ntws thiab them nyiaj rau lub thinning ntawm lwm qhov chaw vim txoj kab uas hla o. Cov txheej txheem no ua tiav qhov muag pom lub luj tshib nrog cov phab ntsa tuab. Nws yog haum rau loj ntau lawm. Yog li ntawd, kub mandrel dabtsi yog khoov tau dhau los ua thawj txoj hauv kev rau carbon steel thiab alloy steel luj tshib. Nws kuj tseem siv los tsim qee qhov tshwj xeeb ntawm stainless hlau luj tshib.

Kev tsim ntawm lub luj tshib plays lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam thiab kev siv. Kev xaiv ntawm txoj kev tsim, txawm tias txias mandrel dabtsi yog khoov los yog kub mandrel dabtsi yog khoov, nyob ntawm seb yam khoom siv, phab ntsa thickness, thiab cov kev cai tshwj xeeb ntawm qhov project. Nkag siab txog cov nuances ntawm cov txheej txheem tsim no yog qhov tseem ceeb rau kev ua tiav ntawm lub luj tshib.
SINO SPECIAL METAL yog lub chaw tsim khoom muaj koob npe ntawm cov kav dej, flanges, thiab fittings. Peb zoo siab tos txais cov lus nug thiab kev txiav txim, muab cov khoom lag luam zoo kom tau raws li koj qhov kev xav tau tshwj xeeb.
