PE hluav taws xob fusion yeeb nkab fittings yog ib hom yeeb nkab uas yog tsim los ntawm cov khoom siv polyethylene thiab tsim los ntawm ntau cov txheej txheem ntau lawm. Nws keeb kwm tuaj yeem taug qab rov qab mus rau xyoo 1940s thaum nws thawj zaug siv los ua cov xov tooj thiab tom qab ntawd hauv thaj chaw dej thiab roj. Nrog kev nce qib ntawm kev siv technology sai, nws tau dhau los ua qhov thib ob zoo tshaj plaws-muag yas raj hauv ntiaj teb.
PE hluav taws xob fusion yeeb nkab fittings muaj ntau yam khoom zoo uas tsis tuaj yeem muab piv rau lwm yam khoom. Ua ntej, lawv muaj lub neej ua haujlwm ntev heev, tshwj xeeb tshaj yog thaum siv dav hauv kev zais engineering. Feem ntau, lawv lub neej kev pabcuam tuaj yeem ntev li 50 xyoo, uas tuaj yeem txo qis lub sijhawm siv rau kev kho dua tshiab thiab rov ua dua tshiab ntawm cov tes hauj lwm qub.
PE hluav taws xob fusion yeeb nkab fittings muaj kev txhim khu kev qha txuas, nrog rau ntau yam pob qij txha thiab muaj zog tensile tsis kam ntawm vuam pob qij txha. Thiab nyob rau hauv ntau qhov chaw hauv av, nws kuj muaj cov yam ntxwv xws li acid tsis kam thiab corrosion kuj. Cov kav dej hauv av tuaj yeem ua tau raws li qhov yuav tsum tau ua thiab tsis nkag siab rau qhov kub thiab txias. Txawm hais tias nws yog lub nroog sab qaum teb lossis lub nroog yav qab teb, nws tuaj yeem siv txawm tias huab cua qhuav lossis ntub. Piv rau PE hluav taws xob fusion fittings, lawv qhov chaw siv yog qhov tsis muaj kev txwv, thiab ob peb lub zog oxides tuaj yeem ua rau lawv, ua rau txo qis kev pab cuam lub neej.
Cov khoom lag luam loj tshaj plaws ntawm PE hluav taws xob fusion yeeb nkab fittings yog lawv muaj peev xwm tsim kho. Tam sim no, kev tsim kho thev naus laus zis ntawm PE hluav taws xob fusion kav hauv Suav teb yog qhov paub tab heev, vim nws qhov yooj yim thiab muaj zog ua haujlwm, uas kuj tau yooj yim lees txais los ntawm ntau lub tuam txhab tsim kho.
Yog vim li cas vim li cas PE hluav taws xob fusion fittings tau txais los ntawm cov pej xeem thiab muaj cov neeg siv khoom lag luam loj txaus yog ze rau cov khoom nws tus kheej.
Kev tsim kho thiab kev teeb tsa ntawm PE hluav taws xob fusion yeeb nkab fittings
PE hluav taws xob fusion yeeb nkab fittings yog cov feem ntau ntawm polyethylene yeeb nkab fittings. Yuav ua li cas txiav txim siab qhov kev tsim kho kom raug yog ib qho txuj ci uas yuav tsum tau ua tiav hauv cov txheej txheem ua
Nyob rau hauv cov nqe lus ntawm voltage, qhov vuam voltage ntawm PE fais fusion yeeb nkab fittings yuav tsum nyob ib ncig ntawm 39 volts, nrog ib tug sib txawv ntawm ntxiv los yog rho tawm 0.6 volts, kom tsis txhob muaj voltage instability thaum lub vuam txheej txheem. Thaum qhov hluav taws xob tsawg dhau los yog nyob rau hauv qhov chaw uas vuam seam kev kho mob tsis tuaj yeem ua tiav ib txwm, peb tuaj yeem siv kho vuam lossis nce lub sijhawm vuam. Thaum vuam, qhov siab tshaj plaws dhau tam sim no yuav tsum tswj tsis pub dhau 100 amperes.
Thaum nws los txog rau hluav taws xob fusion yeeb nkab fittings, qhov cuam tshuam tsis zoo ib yam. Cov tsis muaj kub yaj vuam yog cuam tshuam los ntawm ntau yam, nrog rau kev tsim kho ib puag ncig, nrog rau qhov kub thiab txias, huab cua humidity, thiab lwm yam. Cov kev txwv yuav txawv nyob rau sab qaum teb thiab yav qab teb kev tsim kho. Qhov thib ob muaj feem cuam tshuam yog cuam tshuam los ntawm qhov tsis xws li phab ntsa thickness, qib raw khoom, thiab cov qauv siv. Tam sim no, cov qauv kev lag luam hauv Suav teb yog TSG D2002-2006 thiab GB / T19809, thaum cov qauv rau cov khoom siv roj av yog CJJ engineering txuj ci.
