Nyob rau hauv xyoo tas los no, cov yeeb nkab polyethylene tau dhau los ua qhov kev xaiv zoo tshaj plaws ntawm lub nroog gas pipeline network thiab cov kav dej tsis tshua muaj siab networkdue vim nws qhov tshwj xeeb thiab zoo weld tuaj yeem yooj yim txuas, tawg tsis kam, kev tiv thaiv ib puag ncig, kev noj qab haus huv, kev siv dua tshiab thiab lwm yam. yam ntxwv.Nrog rau qhov muaj koob meej ntawm PE siab piping daim ntawv thov, PE fused fittings rau nws cov kev tsim kho yog yooj yim, txhim khu kev qha vuam thiab tau txais daim ntawv thov dav, tshwj xeeb tshaj yog nyob rau hauv lub nroog gas teb tau nrov, kuj pib dav siv nyob rau hauv lub tshav pob ntawm dej.Kev paub keeb kwm qhia tau hais tias kev siv tswv yim hauv tsev thiab txawv teb chaws nrog polyethylene yeeb nkab kev pab cuam lub neej ntawm qhov yooj yim sib npaug txhim khu kev qha kev sib txuas ntawm vuam.Yog li ntawd, fused fittings thiab hluav taws xob vuam tshuab yog dav siv thiab kev loj hlob sai.Tsis tas li ntawd, steel hlau web skeleton polyethylene compound pub yeeb nkab nyob rau hauv xyoo tas los no, nrog rau qhov zoo ntawm PE yeeb nkab, thiab muaj kev ua tau zoo dua kev ua tau zoo dua li PE raj, tshwj xeeb tshaj yog nyob rau hauv ceev nrooj kev ntxhov siab tawg tsis kam, creep resistance, tsis tu ncua txhua yam kev ua tau zoo. yog zoo dua li cov ntshiab PE yeeb nkab thiab lwm yam, yog li, kuj tau pib dav siv rau cov kav dej hauv nroog.Txoj kev txuas tseem ceeb yog hluav taws xob fusion vuam, sib txuas fused fittings thiab hluav taws xob vuam tshuab yog tsim.

Polyethylene yeeb nkab fusion welded txoj cai

Polyethylene yeeb nkab fusion welded hauv paus ntsiab lus yog embedded nyob rau hauv lub tshuab hluav taws xob vuam mus rau lub puab phab ntsa ntawm fused yeeb nkab tsis kam hlau cua sov, lub cua sov lub zog rau fittings thiab tubing kev twb kev txuas interface melting.Qhov sib txawv ntawm ob qho kawg ntawm lub raj kaw, qhov cuam tshuam ntawm thaj chaw yaj thiab cov yaj nyob rau hauv qhov siab ntawm qhov kub thiab txias, interdiffusion ntawm cov saw hlau molecular, yog tias qhov cuam tshuam rau qhov tob ntawm interdiffusion ntawm molecular saw entanglement tsim nyog qhov ntev, ntuj txias interface qhov tsim nyog vuam lub zog tuaj yeem tau txais, tsim kom muaj kev txhim khu kev qha solder txuas yeeb nkab.Raws li lub hauv paus ntsiab lus ntawm electrofusion vuam thiab kev xyaum hauv tsev thiab txawv teb chaws tau lees paub, cov raj xa dej tuaj yeem tsim cov kev sib txuas ua tau zoo thiab feem ntau yog los ntawm kev tsim cov yeeb nkab fused, qhov kub thiab txias, tsis muaj zog, fused vuam fais fab mov voltage muab fittings thiab cov kav dej stability thiab qhov xwm ntawm cov khoom. ua ntej kev sib txuas ntawm qhov sib txuas, txuas nrog qhov sib txuas ntawm qhov dav dav thiab qhov sib xws, fittings thiab tubing clamp ntawm kev ruaj ntseg thiab kev mob, vuam tsis, vuam ambient kub, tus neeg teb xov tooj theem thiab lwm yam.
