Kev siv hluav taws xob flanges yog cov yeeb nkab fittings uas txuas kav teb siv tshuab hluav taws xob siv hluav taws xob siv tshuab hluav taws xob. Lawv feem ntau siv rau kev nrawm, xau-} Kev sib txuas nruj hauv polyethylene (PE) cov twj luam tawm. Lawv lub ntsiab cai tseem ceeb yog los siv lub ntsaws qhov (socket) qauv nrog cov hlau cua sov sab hauv. Thaum hluav taws xob tau thov, PE cov ntaub ntawv melts thiab fuses nrog sab nraud phab ntsa ntawm cov yeeb nkab ntawm qib molecular. Cua txias tsim lub siab - lub zog ci. Raws li cov txheej txheem, lawv muaj nyob hauv peb hom loj: ncaj -} los ntawm, reducer, thiab flanged.
Nyob rau hauv cov nqe lus ntawm cov yam ntxwv kev ua yeeb yam, hluav taws xob fusion flanges muaj peb cov ntsiab lus zoo: 1) Lub zog sib txuas tuaj yeem ncav cuag tau ntau tshaj li 90% ntawm cov yeeb nkab lub zog, ntau tshaj kev sib txuas txuas ntxiv; 2) Kev sib xyaw ua ke - tswj cov txheej txheem kev tswj hwm vuam cov txheej txheem tsis raug, tshem tawm cov neeg tsav tsheb yuam kev; thiab 3) kev sib txuam fusion nyob ib ncig ntawm tag nrho cov ncig ua kom muaj xau dej xau ntawm 0.1 mpa. Cov qauv kev lag luam tshwj xeeb yog hais txog GB / T 13663.2 -}}}}}}} art 2: fittings, "thiab iso 8085-3.
Cov ntawv thov tsom rau tsib qhov tseem ceeb: sib txuas DN300- dnelines hauv cov dej ntws thiab cov dej ntws; nruab nrab -} siab xa xov (0.4-0.8 mpa) hauv cov roj txheem kev kis roj tsheb; Corrosive Media Thauj Hauv Cov Nroj Tsuag Tshuaj; Polyethylene piping tshuab ntawm ntug platform; thiab txawb yeeb nkab tes hauj lwm rau kev ua liaj ua teb. Nyob rau hauv thee mine lub qhov chaw them nyiaj yug thiab grouting system, nws cov anti-static version ntsib MT558.3.3-2005 mining txheem.
Nruj me ntsis ua raws li plaub {- Cov txheej txheem qib, Scraping Endsment Phaj yuav tsum tau txiav, scraping txheej ntawm 0.2- mm; 2) Lub Chaw Pabcuam Sib Tw Yuav tsum raug tswj tsis pub dhau 0.5 hli; 3) Thaum lub sij hawm lub vuam theem vuam, xaiv lub voltage (39.5 ± 0.5 v) thiab sijhawm (kwv yees li 210 feeb rau DNICH; Thiab 4) thaum lub caij txias txias, cov yeeb nkab yuav tsum txias rau hauv qab 40 degree. Cov kev pheej hmoo ntau suav nrog cov pob qij txha txias (vim yog cov hluav taws xob txias) thiab dhau ntawm cov khoom yuam kev), xav kom muaj kev ntsuas dav hlau siv cov cuab yeej ntsuas tshwj xeeb.
Cov khoom lag luam tseem ceeb ntawm kev ua lag luam yog categorized rau ob chav kawm kub: Qib rau 40 degree), nrog cov kev ntsuas kub los ntawm PN6 rau PN16. Qhov tseeb thev naus laus zis kev tsim kho tau xws li cov neeg siv hluav taws xob uas siv cov chips ntse kom sau cov kab txuas ntxiv, thiab cov pa hluav taws xob nrog ntxiv cov iav fiber ntau ntxiv. Peb daim ntawv pov thawj ua kom zoo rau thaum yuav khoom: TSG), kev haus dej huv si tso cai (rau EU FE CE ntawv pov thawj (rau cov phiaj xwm CE (rau cov haujlwm xa tawm). Tam sim no peb muab PE fusion flanges, ua los ntawm cov qauv hauv tebchaws 1 carbon hlau los yog stainless hlau lossis statent corrosion tsis kam thiab haum muaj zog corrosion thiab haum rau dej thiab roj media. Muaj nyob rau hauv ntau thiab tsawg los ntawm dn50 mus rau DN2000, lawv tuaj yeem xa mus rau peb lub Hoobkas.
