Stainless hlau yeeb nkab haum txoj kev sib txuas: Daim ntawv qhia ua tiav

Taw qhia rau Stainless Hlau Yeeb Nkab Fitting Connections

Stainless hlau yeeb nkab fittings muab faib ua plaub pawg raws li lawv txuas mus rau cov yeeb nkab uas nyob ib sab los yog cov khoom siv: lub qhov (socket fittings), threaded fittings, flanged fittings, thiab welded fittings. Txhua hom kev sib txuas haum rau qhov sib txawv ntawm kev ntsuas siab, qhov kub thiab txias, kev pabcuam, thiab kev saib xyuas yuav tsum tau ua. Nkag siab txog plaub tsev neeg thiab cov txheej txheem tsim tom qab lawv yog thawj kauj ruam mus rau kev tsim cov kav dej txhim khu kev qha.

Plaub txoj kev sib txuas

Qhov (socket) Weld Fittings

Lub qhov (socket weld fittings) tau muab tso rau hauv lub qhov (socket) - zoo li qhov chaw so thiab koom nrog lub qhov (fillet weld) ntawm sab nraud. Lawv muab cov bore du thiab muaj zog tuav, thiab tau dav siv rau cov kav dej me me hauv petrochemical thiab fais fab nroj tsuag. Kev sib txuas ntawm lub qhov (socket) haum txoj kab uas hla mus txog kwv yees li DN50, qhov chaw kuaj hluav taws xob tsis zoo.

Xov Fittings

Threaded fittings cia siab rau tapered los yog parallel threads txiav ntawm qhov haum thiab cov yeeb nkab kawg. Lawv tso cai rau kev sib sau ua ke sai thiab disassembly yam tsis muaj vuam, uas yog qhov tseem ceeb rau kev saib xyuas - cov tshuab siv zog thiab rau cov kev pabcuam siab qis hauv qab li 2 MPa. Xov sealant lossis daim kab xev sealing feem ntau yog siv los lav qhov xau- nruj sib koom ua ke.

Flanged Fittings

Flanged fittings siv bolted flange khub nrog lub gasket ntawm lub ntsej muag. Lawv yog qhov kev xaiv zoo tshaj plaws rau qhov loj - txoj kab uas hla piping, rau kev sib txuas uas yuav tsum tau qhib ntau zaus, thiab qhov twg lub kaw lus txuas nrog cov twj, li qub, thiab cov hlab ntsha. Flange lub ntsej muag tiav thiab cov khoom siv gasket raug xaiv raws li cov kev pabcuam nruab nrab thiab qib siab.

Welded Fittings

Welded fittings tau koom ncaj qha rau cov yeeb nkab los ntawm lub taub qab vuam, muab qhov muaj zog tshaj plaws thiab feem ntau xau- tiv thaiv kev sib txuas. Butt-weld fittings yog tus qauv rau siab-siab, siab- kub, thiab kev pabcuam tu cev. Tag nrho - nkag welds nrog argon shielding yog yuav tsum tau rau austenitic stainless hlau los tiv thaiv corrosion.

Kev tsim cov txheej txheem siv hauv kev tsim khoom haum

Forging

Nyob rau hauv txoj kev forging, cov yeeb nkab kawg lossis ib ntu yog ncab nrog lub tshuab forging kom txo tau cov kab sab nraud. Cov tshuab ua teb forging feem ntau suav nrog hom teb, hom txuas, thiab hom rau cov menyuam. Forging refines lub grain qauv thiab txhim kho cov neeg kho tshuab lub zog ntawm lub tiav haum.

Rolling

Rau ntug rounding, ib tug mandrel muab tso rau hauv lub stainless hlau haum thaum rollers nias rau sab nrauv. Qhov thib ob dov variant ua haujlwm yam tsis muaj mandrel thiab tsim nyog rau sab hauv ntug sib npaug ntawm tuab - cov yeeb nkab phab ntsa. Rolling ua ib lub vojvoog zoo ib yam thiab kev hloov pauv ntawm cov yeeb nkab kawg.

Stamping

Nyob rau hauv txoj kev stamping, ib tug tapered core mounted rau lub punch nthuav cov yeeb nkab kawg mus rau qhov yuav tsum tau muaj qhov loj thiab cov duab. Stamping muaj txiaj ntsig zoo rau kev tsim khoom loj ntawm cov reducers, expanders, thiab flared xaus nyob rau hauv ib tug nruj dimension kam rau ua.

Khoov

Bending forming siv peb txoj kev tseem ceeb: txoj kev ncab, txoj kev stamping, thiab txoj kev rau cov menyuam. Cov txheej txheem rau cov menyuam siv peb mus rau plaub lub rollers, suav nrog ob lub taag rollers thiab ib qho adjustable rollers, tswj lub vojvoog khoov. Khoov yog siv los tsim lub luj tshib thiab nkhaus seem nrog lub vojvoog tswj.

Bulging

Nyob rau hauv txoj kev bulging, roj hmab yog muab tso rau hauv cov yeeb nkab thiab compressed nrog ib tug punch kom cov yeeb nkab expands mus rau hauv cov duab. Nyob rau hauv hydraulic bulging, nruab nrab ntawm cov yeeb nkab yog ntim nrog cov kua thiab cov kua siab ua rau cov contour xav tau. Bulging feem ntau yog siv los tsim cov hauv qab thiab corrugated expansion pob qij txha.

Xaiv Txoj Kev Sib Txuas Zoo

Kev txiav txim siab zoo

Tsis hais txog ntawm txoj kev sib txuas, fittings yuav tsum tau muab nrog cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj traceable rau lub yaj, thiab qhov ntsuas qhov ntev yuav tsum paub meej tias cov chav kawm siab thiab kev npaj kawg. Rau corrosive los yog tu cev kev pab cuam, lub puab nto tiav thiab tsis muaj crevices ntawm lub sib koom yog txiav txim. Gnee Steel muab cov khoom siv stainless hlau fittings thiab titanium cov khoom tsim thiab sim ua raws li cov qauv ASTM.

Cov lus nug nquag

Txoj kev txuas stainless hlau twg yog qhov muaj zog tshaj?

Butt-welded kev sib txuas yog qhov muaj zog tshaj plaws vim tias tag nrho - nkag mus rau weld tsim ib qho txuas txuas ntxiv nrog lub zog ze rau ntawm cov yeeb nkab niam txiv.

Thaum twg threaded fittings yuav tsum zam?

Threaded fittings yuav tsum tau zam nyob rau hauv siab -kev co, thermal- kev caij tsheb kauj vab, thiab siab - lub zog siab tshaj li ntawm 2 MPa, qhov twg xov xau yuav ua rau muaj kev pheej hmoo.

Vim li cas flanged kev sib txuas siv hauv cov nroj tsuag tshuaj?

Flanged kev sib txuas cia li qub, twj tso kua mis, thiab cov hlab ntsha tuaj yeem raug cais tawm thiab muab tshem tawm kom tsis txhob txiav cov kav dej.

Lub qhov (socket) vuam fittings puas tuaj yeem kuaj xyuas hluav taws xob?

Lub qhov (socket) welds yog qhov nyuaj rau kev tshuaj xyuas nrog cov duab hluav taws xob, uas yog ib qho laj thawj uas lawv txwv rau cov kav dej me me uas siv lwm txoj hauv kev tshuaj xyuas.

Dab tsi yog qhov txawv ntawm tus reducer ua los ntawm stamping thiab ib qho ua los ntawm forging?

Stamping nthuav dav cov yeeb nkab kawg nrog cov punch tapered thiab muaj txiaj ntsig rau kev tsim khoom loj, thaum forging stretches thiab compresses cov khoom los ua kom cov qauv nplej kom siab dua - kev pab cuam lub zog.

Yuav ua li cas lub vuam tiv thaiv thaum lub sij hawm stainless hlau yeeb nkab vuam?

Argon shielding yog siv rau ob qho tib si sab nraud thiab sab hauv ntawm lub vuam los tiv thaiv oxidation thiab khaws cov corrosion kuj ntawm austenitic stainless hlau.
