Hom txheej txheem ntau lawm rau stainless hlau flanges
Stainless hlau flange yog ib qho tseem ceeb rau kev sib txuas cov kav dej thiab cov khoom siv. Nws muaj cov yam ntxwv ntawm kub tsis kam, corrosion kuj thiab zoo sealing. Cov txheej txheem ntau lawm stainless hlau flange feem ntau muab faib ua plaub hom: forging, casting, txiav, thiab dov.
(1) Cam khwb cia hlau stainless flange
Cov txheej txheem ntawm kev txhaj tshuaj molten hlau rau hauv pwm los nrum stainless hlau flanges yog hu ua txoj kev casting. Qhov zoo yog: cov duab zoo thiab qhov loj ntawm qhov khoob, qhov ntim me me, tus nqi qis, thiab cov pwm tuaj yeem hloov kho raws li cov neeg siv khoom xav tau los tsim cov duab ntau dua. Disadvantages: Casting defects (pores, kab nrib pleb, inclusions), tsis zoo streamlined internal qauv ntawm lub casting, tsis zoo shear quab yuam thiab tensile quab yuam. Tau kawg, tseem muaj ntau dua cam khwb cia hlau stainless flange txheej txheem uas tuaj yeem txo qhov tsis zoo. Piv txwv li, centrifugal stainless hlau flanges yog ib hom cam khwb cia hlau stainless flanges. Txoj kev centrifugal yog ib txoj hauv kev zoo tshaj plaws los tsim cov hlau stainless flanges. Stainless hlau flanges cam khwb cia nyob rau hauv txoj kev no yog ntau finer tshaj li cov xuab zeb casting txheej txheem, qhov zoo yog ntau txhim khu kev qha, thiab nws tsis tshua muaj teeb meem xws li pores, tawg, thiab trachoma.Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm centrifugal casting ntawm stainless hlau flanges.
(2) Forged stainless hlau flange
Forged stainless hlau flanges feem ntau muaj cov ntsiab lus qis dua li cam khwb cia hlau stainless flanges thiab tsis tshua muaj xeb. Cov forgings muaj qhov zoo streamlines thiab cov qauv denser. Lawv cov khoom siv kho tshuab zoo dua li cov cam khwb cia stainless hlau flanges thiab lawv tuaj yeem tiv taus siab dua shear rog thiab tensions. Txuas ntxiv.
Feem ntau forged stainless hlau flanges yog forged thiab forged.
Forged flange yog flange tsim los ntawm kev kub kub ntawm cov ntaub ntawv hlau thiab tom qab ntawd ntaus. Lub ntsiab feature ntawm cov txheej txheem no yog siv qhov kub thiab txias siab kom maj mam deform cov khoom siv hlau kom nws cov duab thiab kev ua tau zoo.
Qhov txawv ntawm forged flange thiab forged flange yog tias nws siv cov tshuab ua haujlwm los pwm cov ntaub ntawv hlau, txheej txheem hlau zoo ib yam li forged flange. Cov txheej txheem no muaj feem xyuam rau forging deformation es tsis yog phau ntawv forging.
Hauv qab no yog cov lus piav qhia ntxaws ntxaws ntawm forged stainless hlau flanges thiab forged stainless hlau flanges.
(3) Txiav stainless hlau flange
Ncaj nraim txiav tawm lub flange sab hauv thiab sab nraud txoj kab uas hla thiab thickness disks ntawm stainless hlau nruab nrab phaj, thiab ces ua cov ntsia liaj qhov rooj qhov thiab dej kab. Qhov loj ntawm stainless hlau flanges txiav thiab tsim feem ntau tsis tshaj DN150. Yog tias qhov loj dua DN150, tus nqi yuav nce ntxiv.
(4) Rolled stainless hlau flange
Cov txheej txheem ntawm kev txiav stainless hlau nruab nrab daim hlau rau hauv ib daim hlab thiab tom qab ntawd dov lawv mus rau hauv lub voj voog feem ntau yog siv los ntawm qee qhov loj stainless hlau flanges. Tom qab ua tiav dov, nws yog welded, ces flattened, thiab tom qab ntawd cov waterline thiab bolt qhov ua tiav. Vim tias cov khoom siv raw yog nruab nrab phaj, qhov ceev yog qhov zoo. Cov txheej txheem vuam ntawm qhov sib txuas ntawm cov dov flange yog qhov tseem ceeb tshaj plaws, thiab yuav tsum tau kuaj X-ray lossis ultrasonic zaj duab xis.
