Dab tsi yog cov txheej txheem tsim khoom rau BS4504 flanges?
Nws tsim cov txheej txheem ntawm BS4504 flange feem ntau suav nrog forging, casting, txiav thiab dov, ntawm cov forging thiab casting yog ob txoj hauv kev loj tshaj plaws. Cov txheej txheem sib txawv ncaj qha cuam tshuam rau cov khoom siv kho tshuab, siv cov xwm txheej thiab kev tswj tus nqi ntawm flange.
1, Forged Flange
Forging yog cov txheej txheem ntawm cov cua kub hlau rau hauv lub xeev yas thiab siv lub zog los ntawm cov khoom siv forging los ua nws, ua rau cov qauv denser thiab kev ua haujlwm zoo dua.
Qhov zoo:
Fine grain qauv, zoo streamline, muaj zog tensile thiab shear kuj
Cov ntsiab lus qis carbon tsawg, tsis yooj yim rau xeb, tshwj xeeb tshaj yog haum rau siab -siab, siab - kub lossis corrosive ib puag ncig
Tsis muaj qhov tsis xws luag xws li pores thiab tawg, txhim khu kev qha sealing kev ua tau zoo
Cov txheej txheem ntau:
Dawb forging: haum rau ib thooj lossis me me batch ntau lawm, nrog cov cuab yeej yooj yim tab sis loj machining nyiaj pub dawb
Qauv Forging: High precision, du nto, haum rau kev tsim khoom loj, cov qauv siv lead ua tsis sib xws
Cov ntawv thov: kev lag luam uas muaj kev nyab xeeb siab xws li roj, nkev, hluav taws xob, tshuaj, thiab lwm yam
2, Casting txheej txheem (Cast Flange)
Casting yog txheej txheem ntawm pouring molten hlau rau hauv pwm thiab txias nws rau daim ntawv, uas yog haum rau complex qauv thiab muaj tus nqi qis.
Qhov zoo:
Muaj peev xwm tsim cov flanges nrog cov duab nyuaj, xws li cov hlua txuas ntxiv lossis cov kev sib txuas tshwj xeeb
Tus nqi qis, tsim nyog rau qhov loj - nplai, qis- siv cov xwm txheej xav tau
Qhov tsis zoo:
Tej zaum yuav muaj qhov tsis xws luag xws li pores, suav nrog, thiab cov kab nrib pleb sab hauv, thiab cov khoom siv kho tshuab kuj tsis muaj zog.
Lub koom haum yog xoob, thiab nws cov compressive thiab cuam tshuam tsis zoo li ntawm forgings
Cov txheej txheem tshwj xeeb:
Centrifugal casting: Hlau yog tsim nyob rau hauv siab - nrawm tig pwm, nrog cov qauv ntom ntom thiab zoo dua li cov xuab zeb casting. Nws yog feem ntau siv nyob rau hauv zus tau tej cov tiaj vuam flanges
Cov ntawv thov: Kev kho dej, HVAC, cov kav dej dav dav
3, Txiav Phaj Flange
Txiav lub flange dawb paug ncaj qha los ntawm steel phaj thiab ces tshuab nws.
Txheej txheem: Cov khoom txiav → Txiav sab hauv thiab sab nraud → Drilling bolt qhov → Ua cov txheej txheem sealing
Yam ntxwv:
Kev siv cov khoom siv tsawg, tab sis tsis xav tau pwm, haum rau cov kev xav tau ib ntus ntawm qhov nruab nrab thiab qis, tsis yog - qhov loj me
Lub zog yog qis dua li ntawm forged flanges, thiab vim tsis muaj txheej txheem forging, cov hlau fibers tsis compacted.
Cov xwm txheej siv tau: cov haujlwm me me, kev saib xyuas thiab hloov pauv, kev sib txuas tsis yog qhov tseem ceeb
4, Rolled Flange
Yob cov hlau phaj rau hauv ib lub voj voog uas siv lub phaj dov tshuab, welding cov pob qij txha, thiab tom qab ntawd ua cov txheej txheem.
Yam ntxwv:
Haum rau txoj kab uas hla loj flanges (xws li DN1000 thiab siab dua), daws qhov kev txwv loj ntawm forging lossis casting
Tus nqi siab, tab sis muaj peev xwm ua tiav cov txheej txheem loj loj
Qhov zoo ntawm weld seam ncaj qha cuam tshuam rau tag nrho lub zog thiab yuav tsum nruj tsis yog -kev kuaj kev puas tsuaj
Daim ntawv thov thaj chaw: Cov khoom siv hnyav xws li cov cua turbine loj, cov nkoj, thiab cov chaw tawm ntug dej hiav txwv
