Rubber lined Npauj Npaim Valve, sab hauv nrog ebonite hauv ob sab phlu ntawm thickness 3mm los yog 5mm, dav siv nyob rau hauv cov dej phwj tuaj, tshuaj kev lag luam, dej hiav txwv kev kho mob thiab desalinization project thiab lwm yam.
Tus qauv tsim: BS EN593, AWWA C504, API 609
Lub ntsej muag ntev: EN558-1 / ISO5752 series 14 lossis Series 13, AWWA C504
Loj: DN300 - DN3600 / 12 "-144"
Kev ntsuas siab: PN6-PN10-PN16-PN25-PN40 / 75psi-150psi-250psi-350psi-580psi
Tag nrho cov roj hmab lined npauj npaim li qub ntawm kev ntseeg siab, tsim kom muaj zog raws li qhov phem tshaj plaws nyob ib puag ncig.
Ebonite hauv ob sab phlu: muaj tshuaj zoo stability, zoo heev tshuaj corrosion kuj thiab organic hnyav tsis kam, tsis tshua muaj dej nqus, siab tensile zog thiab zoo heev hluav taws xob rwb thaiv tsev etc.features.
Lub ebonite hauv ob sab phlu tsim cov txheej txheem txuas ntxiv ntawm cov substrate ntxiv cov qauv tsim tshwj xeeb thiab cov txheej txheem ntawm kev sib koom ua ke kom cais cov ferrous substrate los ntawm cov kev pabcuam nruab nrab, yog li ua kom cov khoom siv sijhawm ntev.
Rau cov kua dej corrosive, nws yuav yog ib qho kev daws teeb meem ntau dua.
Cov cheeb tsam yuav tsum tau tiv thaiv los ntawm ebonite hauv ob sab phlu yuav tsum tau xuab zeb blasted kom pom cov hlau dawb thiab ncav cuag kev huv si Sa 2.5 rau ISO 8501 thiab roughness nruab nrab G rau ISO 8503.
Nyob rau hauv ib puag ncig nrog cov av noo tsis tshaj 60% thiab qhov kub ntawm 15-40 ℃, siv cov cuab yeej hauv ob sab phlu, xws li lub siab rau cov menyuam thiab scraper kom ua tiav cov ntaub ntawv roj hmab thiab cov substrate raws li cov txheej txheem nruj thiab cov kev cai.
Lub ebonite hauv ob sab phlu vulcanization txheej txheem nrog cua kub los yog chav nyob rau hauv lub vulcanization kettle.
Cov txheej txheem tom ntej tuaj yeem pib tsuas yog tom qab dhau ntau yam kev sim thiab tshuaj xyuas (kev tshuaj xyuas qhov muag, hluav taws xob kuaj pom rau hnub so / pinholes / tawg, adhesion test thiab hardness test etc.)
Lub hardness ntau yam yuav tsum ua tiav Shore D 75 ± 5.
Kev tiv thaiv corrosion sab nraud:Cov txheej txheem pleev xim hauv qab no tau muab rau kom haum rau C5 corrosivity qeb raws li EN ISO 12944-2,
Epoxy zinc-nplua nuj primer - 60μm, Epoxy micaceous hlau / nruab nrab xim - 120μm, Acrylic polyurethane tiav xim - 60μm, Tag nrho qhuav sau thickness (DFT) 240μm
Epoxy iav flake primer- 80μm, Epoxy iav flake xim ob txheej - 160μm, Tag nrho qhuav sau thickness (DFT) 240μm
Tag nrho cov fastenings sab hauv thiab sab nraud xws li txiv ntseej, bolts, screws thiab fittings yuav tsum yog stainless hlau qib 316L los yog duplex stainless hlau.
Tag nrho cov roj hmab lined npauj npaim li qub tsim nyog yuav tsum tau kho nyob rau hauv txoj hauj lwm ntsug los yog kab rov tav txoj hauj lwm.
Lub qhov muag lifting / lifting nuv tsau nyob rau hauv txoj hauj lwm tsim nyog kom lub valve tuaj yeem nqa tau hauv txoj hauj lwm ntsug lossis kab rov tav.
