Siab Bearing Peev Xwm Ntawm PE Yeeb Nkab

Kev siv cov kav dej PE hauv kev lag luam tuaj yeem hais tau zoo heev. Thaum lub sij hawm vuam txheej txheem, vim nws cov ntsiab lus tig ntau thiab kev ntxhov siab, nws yuav dhau los ua qhov tsis muaj zog txuas hauv cov kav dej. Yog li ntawd, nws yog ib qho tsim nyog yuav tau ua qhov kev ntsuam xyuas sib piv ntawm hydrostatic zog ntawm welded yeeb nkab fittings. Tom ntej no, cia peb luv luv to taub txog lub siab muaj peev xwm ntawm PE kav:
Nyob rau hauv kev siv engineering siv, lub siab tsis kam ntawm cov kav dej khoov yuav tsum yog ib theem qis dua li ntawm cov kav dej polyethylene ntawm tib qib, thaum lub siab tsis kam ntawm qhov sib npaug ntawm txoj kab uas hla Sanyuan yuav tsum raug txo los ntawm ob theem.
2. Cov txheej txheem tsim khoom ntawm PE welded yeeb nkab fittings yuav tsum tau tswj nruj me ntsis, thiab cov txheej txheem tsim nyog yuav tsum tau tsim los ua kom cov khoom zoo.
3. Tsim cov qauv tsim nyog rau welded yeeb nkab fittings thiab teeb tsa kev ruaj ntseg coefficients rau cov fittings.
4. Kev ntsuas tau zoo tuaj yeem siv rau hauv cov ntawv thov engineering tshwj xeeb txhawm rau ntxiv dag zog rau cov welds ntawm cov kav dej polyethylene los ntawm kev khi lossis nchuav pob zeb. Yuav ua li cas los xyuas qhov zoo ntawm cov kav dej PE yog kom pom qhov pom ntawm lub nplhaib vuam los xyuas nws qhov zoo. Qhov tsim nyog vuam sib koom ua ke tsis puas, deformed, los yog tsis muaj xim, thiab tus ncej me me hauv lub qhov nce ib txwm. Tom qab vuam cov yeeb nkab fittings, cov cim yog pom tseeb. Txawm li cas los xij, kev ntseeg siab ntawm txoj kev no tsis yog siab, vim nws tsis tuaj yeem kuaj pom qhov tsis xws luag hauv thaj chaw sib txuas thiab tsis tuaj yeem lav qhov kev ntseeg tau ntawm kev sib txuas.
Ob txoj hauv kev yog kev sim ua kom puas tsuaj. Ua tensile, dabtsi yog khoov, tensile creep tests, thiab lwm yam ntawm lub melting point.
