Feem ntau cov haujlwm tiag tiag siv tsawg kawg ob ntawm peb hom no. Ib txoj kab faib hluav taws xob tshiab feem ntau yog butt fused raws nws txoj kev, nrog electrofusion rau cov tie-ins, thiab saddles ntawm txhua service tee thiabsocket fusionSab hauv cov thawv ntsuas. Cov txuas tag nrho yog ua los ntawm polyethylene thiab txhua qhov muaj zog zoo ib yam yog ua kom raug – tab sis cov kauj ruam, cov cuab yeej, thiab cov txuj ci ntawm tus neeg ua tsis yog ib yam uas hloov tau.
Yuav sau dab tsi rau hauv specification
Npe txoj kev rau txhua qhov haujlwm, teev cov neeg ua haujlwm rau txhua txoj kev cais, thiab xyuas kom muaj ib daim ntawv sau tshuab rau txhua qhov txuas qhia tias leej twg yog tus neeg ua haujlwm. Hauv ib qho project sib xyaw, cov ntaub ntawv traceability yog txoj kev tsuas yog los paub tom qab tias txoj kev twg ua rau qhov txuas uas ntws tawm.
Cov khoom txuas phim rau lub raj
Txawm siv txoj kev twg, qhov txuas yuav tsum phim DN ntawm lub raj.SDRand compound grade. Bothelectrofusion fittingsandbutt fusion fittingsLawv yog molded raws li SDR, thiab ob pawg no tsis yog lwm txoj kev – lawv raug vuam los ntawm cov tshuab sib txawv thiab tau teev tseg cais.
Cov khoom seem thiab kev teb ceev
Ib pab neeg kho tsis tuaj yeem txuas hluav taws xob hauv ib lub qhov dej ntub dej thaum ob teev sawv ntxov. Cov tuam txhab hluav taws xob khaws cov khoomelectrofusion couplings, saddles thiab end caps hauv qhov loj uas lawv network siv ntau tshaj, nrog rau ib qhowelding machineuas saib xyuas nws cov pob qij txha. Kev npaj network nrog daim ntawv teev khoom ntawd yog yam ua rau muaj peev xwm teb tau thaum muaj xwm ceev.
Cov Lus Nug Feem Ntau
Cov lus nug txog txoj kev uas tshwm sim ntau tshaj plaws thaum lub sijhawm piav qhia.
Puas yog pob qij txha electrofusion muaj zog dua pob qij txha pob qij txha sib xyaw?
Ob qho, thaum ua kom raug, muaj zog dua li lub raj uas lawv txuas, uas yog qhov ob txoj kev raug sim. Qhov txawv tiag tiag tsis yog zog tab sis yog kev sib npaug: electrofusion tau txais nws cov teeb tsa los ntawm qhov txuas thiab siv ntau dua kev npaj saum npoo, thaum butt fusion nyob ntawm tus neeg ua haujlwm thiab lub tshuab.
Vim li cas electrofusion thiaj kim dua rau txhua pob qij txha?
Vim txhua qhov txuas siv ib qho molded fittings nrog ib lub coil hauv paus, thaum butt fusion tsuas siv hluav taws xob thiab ib me ntsis raj xwb. Tus nqi ntxiv no muab koj nkag mus hauv qhov chaw me me, ib qho preset uas tsis tuaj yeem ua yuam kev, thiab ib daim ntawv sau tshuab. Rau cov txuas uas xav tau, tsis muaj kev xaiv pheej yig dua.
Qhov loj tshaj plaws uas koj tuaj yeem electrofuse yog pes tsawg?
Cov fittings ua tau txog DN630, thiab rau yam loj dua, butt fusion yog siv hloov. Qhov txwv yog hais txog kev siv tau ntau dua li kev xav: lub zog uas xav tau los tuav ib qho fitting loj kom ruaj khov, thiab lub zog xav tau los kub ib lub coil ntev, ob leeg nce sai raws li qhov dav loj dua.
Koj puas tuaj yeem tig cov tshuaj yej thaum nag?
Butt fusion thiab socket fusion tuaj yeem npog nrog lub tsev pheeb suab. Electrofusion tuaj yeem ua tau thaum nag me me yog tias qhov txuas tau tiv thaiv thiab cov raj kawg qhuav thiab huv, tab sis dej hauv qhov chaw yuav hloov mus ua pa kub thiab puas weld – yog li ntau tus neeg ua haujlwm tsuas zam kev sib txuas hauv qhov chaw qhib thaum nag hnyav.
Kuv puas tseem yuav tsum tau socket fusion yog tias kuv muaj electrofusion?
Rau cov haujlwm me me hauv tsev, feem ntau pheej yig dua, nrog cov cuab yeej nyhav tsawg thiab nqi nruab qis dua. Nws tsis yog hloov electrofusion ntawm cov raj loj faib hluav taws xob, thiab nws muaj qhov chaw tsawg tshaj plaws rau kev yuam kev ntawm tus neeg ua haujlwm ntawm peb txoj kev, yog li kev cob qhia tseem ceeb dua qhov twg los.
Txhua lub joint yuav tsum sau li cas?
Yam tsawg kawg, koj yuav tsum muaj tus lej joint thiab qhov chaw, batch uas haum thiab traceability code, tus neeg ua haujlwm, thiab cov settings thiab cov txiaj ntsig uas lub tshuab tau khaws cia. Cov tshuab electrofusion thiab butt fusion niaj hnub no export cov ntaub ntawv no tau yooj yim. Yog tias tsis tau sau rau hauv ib qhov project, nrhiav tau thawj qhov joint uas ua tsis tau yuav nyuaj heev.
