Kev txuas cov yeeb nkab yas rau lub qhov dej hlau lossis lub twj tso kua mis yog ib qho teeb meem tas li. Cov khoom siv hloov pauv tshwj xeeb kim heev, hnyav, thiab tuaj yeem ua rau muaj qhov tsis ua haujlwm tshiab rau hauv koj lub cev.

Ib qho kawg ntawm lub raj yog ib daim yeeb nkab luv luv uas muaj lub dab tshos uas tau vuam rau qhov kawg ntawm lub yeeb nkab. Nws yog siv nrog lub flange hlau los tsim kom muaj kev sib txuas uas tshem tau, ntsia hlau uas muaj zog thiab tsim nyog tus nqi.

Kuv nco qab tias kuv tau tham txog ib qhov project loj nrog ib tug khub. Lawv tau ntsib teeb meem nrog tus nqi ntawm cov flanges stainless hlau uas yuav tsum tau txuas lawv cov kav dej HDPE rau ntau yam twj thiab cov tank. Thaum kuv qhia lawv lubQhov kawg ntawm lub qhov (stub end) thiab lub flange backing system, nws yog ib qho kev tshwm sim. Lawv pom tias lawv tuaj yeem tau txais qhov kev tiv thaiv xeb ntawm HDPE sab hauv, tab sis siv pheej yig dua,Cov hlau carbon coated rau cov flanges thaub qabuas muab lub zog clamping. Qhov kev hloov pauv yooj yim no tau txuag lawv ntau ntawm lawv cov peev nyiaj siv. Nws yog ib qho piv txwv zoo meej ntawm kev tsim vaj tsev ntse uas daws tau ntau yam teeb meem ib zaug.

HDPE stub kawg yog dab tsi?

Koj pom ib feem uas zoo li lub flange tab sis ua los ntawm yas. Koj tsis paub tseeb tias nws yog ib lub flange tag nrho lossis lwm yam, uas ua rau kev txiav txim tsis meej pem.

Ib qho kawg ntawm HDPE yog ib qho khoom siv tshwj xeeb uas ua los ntawm High-Density Polyethylene. Nws muaj ib ntu yeeb nkab luv luv nrog lub dab tshos zoo li disc. Nws tsis yog ib lub flange nws tus kheej tab sis siv nrog lub flange hlau backing los tsim kev sib txuas.

Qhov zoo ntawm HDPE stub kawg yog tias nws tsim ib lub kaw lus ob ntu uas muab qhov zoo tshaj plaws rau koj. Lub stub kawg nws tus kheej yog welded ncaj qha rau koj cov yeeb nkab HDPE. Qhov no txhais tau tias cov kua hauv cov yeeb nkab tsuas yog kov ib yam khoom xwb:HDPE uas tsis muaj xeb, tiv taus corrosionLub dab tshos uas nthuav dav, lossis "lap," ntawm qhov kawg ntawm lub stub ua haujlwm ua lub ntsej muag kaw. Tom qab ntawd, ib qho sib caishlau thaub qab flangeswb hla lub yeeb nkab tom qab qhov kawg ntawm lub stub. Lub flange hlau no muab lub zog los ntsia hlau qhov kev sib txuas rau lwm qhov flanged Cheebtsam, xws li lub valve lossis twj tso kua mis. Vim tias lub flange hlau yeej tsis kov cov kua, koj tsis tas yuav siv cov hlau kim, tiv taus corrosion. Qhov kev sib cais ntawm lub luag haujlwm no - qhov kawg ntawm lub stub yas rau lub foob thiab lub flange hlau rau lub zog - ua rau nws yog qhov kev daws teeb meem zoo thiab pheej yig rau kev txuas yas rau hlau.

Cov hom stub kawg sib txawv yog dab tsi?

Koj yuav tsum tau xaj cov kawg ntawm cov kav dej, tab sis saib cov hom sib txawv uas teev tseg. Kev xaiv hom tsis raug rau koj cov yeeb nkab loj lossis cov khoom siv yuav ua rau muaj kev ncua sijhawm ntawm qhov chaw thaum lawv tsis haum.

Cov hom HDPE stub ends tseem ceeb yog txhais los ntawm lawv txoj kev vuam. Socket fusion stub ends yog rau cov kav dej me dua, thaum butt fusion stub ends yog siv rau cov kav dej loj dua.

Ntawm Pntek, peb tsim ob hom no kom tau raws li qhov xav tau ntawm txhua qhov project. Hom uas koj xaiv nyob ntawm qhov loj ntawm cov yeeb nkab uas koj siv.

Qhov (Socket Fusion) vs. Qhov (Butt Fusion) Qhov (Stub Ends)

Peb liQhov (Socket Fusion Stub Ends)yog tsim los rau cov kav dej me me, feem ntau los ntawm20mm txog 110mmCov no muaj ib lub qhov (socket), lossis qhov khoob, uas cov yeeb nkab raug ntxig rau hauv tom qab ob qho tib si raug cua sov. Txoj kev no yog qhov ceev thiab yooj yim rau cov yeeb nkab me me, yooj yim tswj tau ntau dua uas feem ntau pom muaj nyob rau hauv cov kav dej lossis cov kab kev lag luam me me.

Peb liKev Txhaj Tshuaj Butt Fusion HDPE Stub Endsyog rau cov haujlwm loj dua, nrog rau qhov ntau thiab tsawg xws li50mm txog 1200mmRau cov kav dej loj no, nws yog qhov siv tau zoo dua los txuas cov kawg ncaj qha. Qhov kawg ntawm qhov kawg ntawm lub raj xa dej thiab qhov kawg ntawm cov kav dej raug cua sov thiab tom qab ntawd nias ua ke, lossis "butted," los ua ib qho vuam. Qhov no yog tus qauv rau cov kav dej loj thiab cov kav dej ua haujlwm hauv kev lag luam.

Cov stub ends no ua li cas?

Ib qho kawg ntawm lub stub yuav tsum tiv taus qhov siab ntawm lub bolting. Koj txhawj xeeb tias ib qho khoom yas uas ua tsis zoo yuav tawg lossis ua tsis tiav, ua rau muaj qhov xau loj ntawm qhov chaw sib txuas tseem ceeb.

Cov kawg ntawm cov kav hlau zoo yog ua los ntawm kev txhaj tshuaj molding. Peb txhaj cov resin PE100 uas yaj thiab zoo rau hauv cov pwm hlau uas tau tsim los ntawm kev kub siab heev, ua rau muaj ib daim uas tuab, tsis muaj qhov khoob, thiab muaj zog heev.

Cov txheej txheem tsim khoom yog qhov tseem ceeb rau kev ntseeg tau ntawm cov khoom siv. Txhua yam pib nrog cov khoom siv raw zoo tshaj plaws - peb siv cov pellets PE100 uas muaj qhov ceev ceev. Cov pellets no raug yaj mus rau hauv lub xeev ua kua. Cov yas yaj no ces raug txhaj rau hauv lub pwm hlau uas tau khov kho uas tau ci kom zoo li daim iav. Lub siab siab no ua kom cov yas puv txhua lub ces kaum ntawm cov pwm, tsim kom muaj qhov ceev ceev thiab tsis muaj cua npuas sab hauv lossis qhov chaw tsis muaj zog. Cov khoom raug tuav hauv qab lub siab thaum nws txias thiab khov ua ntej raug ntiab tawm ntawm cov pwm. Peb cov txheej txheem tsis siv neeg ua kom ntseeg tau tias txhua qhov kawg ntawm lub qhov, txij li qhov me tshaj plaws mus rau qhov loj tshaj plaws, muaj qhov loj me zoo meej, tshwj xeeb tshaj yog qhov tuab thiab qhov tiaj tus ntawm lub dab tshos flared, uas yog qhov chaw kaw tseem ceeb. Cov txheej txheem nruj no lav qhov koj ntseeg siab tau.

Lub hom phiaj tseem ceeb ntawm kev siv lub stub kawg yog dab tsi?

Koj yuav tsum txuas cov yeeb nkab yas rau lub qhov dej hlau. Kev vuam lawv tsis yooj yim sua, thiab kev siv cov khoom siv tshwj xeeb tuaj yeem kim thiab tsim cov pob qij ntxiv uas yuav xau.

Lub hom phiaj tseem ceeb ntawm qhov kawg ntawm lub stub yog los tsim ib qho chaw txuas uas tshem tau, flanged ntawm cov yeeb nkab yas, feem ntau yog rau kev koom nrog nws rau lub flange hlau ntawm lub valve, twj tso kua mis, lossis lub tank.

Lub rooj sib dhos kawg ntawm lub stub yog ib qho kev daws teeb meem uas muaj ntau yam nrog ntau lub hom phiaj tseem ceeb:

• Koom nrog Cov Txheej Txheem Sib Txawv:Qhov no yog nws txoj haujlwm thib ib. Nws muab ib txoj hauv kev nyab xeeb thiab txhim khu kev qha los txuas lub raj xa dej HDPE uas tau vuam rau lub raj xa dej flanged.

• Tsim Cov Pob Qij Txha Uas Tshem Tau:Cov kav dej uas vuam tag nrho yog qhov ruaj khov. Los ntawm kev siv cov kawg ntawm cov kav dej, koj tsim cov chaw tawg tseem ceeb. Qhov no yog qhov tseem ceeb rau kev teeb tsa cov khoom siv xws li cov twj tso kua mis lossis cov lim dej uas yuav tsum tau tshem tawm rau kev saib xyuas lossis hloov pauv tom qab.

• Txo Cov Nqi:Zoo li kuv tau hais lawm, lub flange backing tsis kov cov khoom siv hauv lub yeeb nkab. Qhov no tso cai rau koj siv cov flange backing steel uas pheej yig thiab tus qauv es tsis txhob siv cov flanges stainless steel kim lossis alloy kim, uas ua rau cov nqi khoom siv tsawg dua.

• Ua kom yooj yim rau kev teeb tsa:Lub flange backing tuaj yeem tig tau yooj yim ncig lub yeeb nkab ua ntej nws raug bolted. Qhov no ua rau nws yooj yim heev rau cov neeg teeb tsa los teeb tsa cov qhov bolt nrog lub flange txuas. Nws tshem tawm txoj haujlwm nyuaj ntawm kev ntswj ib feem yeeb nkab hnyav kom tau txais cov qhov bolt kom phim.
