Kev tsim thiab siv cov kav dej HDPE thiab fittings yuav tsum ua raws li cov qauv kev lag luam hauv teb chaws thiab kev lag luam- xws li GB/T 13663, Polyethylene (PE) Piping Systems for Water Supply- ntawm lwm tus. Cov qauv no tsim cov kev qhia meej meej txog cov khoom siv, qhov ntev, thiab cov yam ntxwv ntawm kev ua haujlwm ntawm cov kav dej thiab fittings, yog li ua kom cov khoom zoo thiab kev nyab xeeb.
Txheej txheem cej luam ntawm Cov Qauv Txheej Txheem rau HDPE Yeeb Nkab thiab Fittings
Hauv kuv lub tebchaws, tau tsim cov qauv kev qhia dav dav rau High-Density Polyethylene (HDPE) kav, feem ntau muab faib ua ob theem hierarchical: cov qauv hauv tebchaws thiab cov qauv kev lag luam. GB / T 13663 series ntawm specifications tswj cov kev xav tau rau cov kav dej, thaum CJ / T 250 tus qauv siv rau lub tsev tso dej; Tsis tas li ntawd, cov kev cai hauv zos -xws li DG/TJ08-2314- yog tsim los muab cov kev cai ntxiv raws li cov xwm txheej tshwj xeeb. Cov qauv no tau tsim cov kev cai tshwj xeeb rau cov kev qhia tseem ceeb-xws li nominal txoj kab uas hla specifications, phab ntsa thickness tsis, thiab nplhaib txhav qib-yog li tsim lub hauv paus rau kev tsim, tshuaj xyuas, thiab installation ntawm HDPE kav.
Tus qauv ntawm cov yeeb nkab txoj kab uas hla specifications tsis yog ib qho teeb meem ntawm cov khoom sib hloov; nws tseem cuam tshuam ncaj qha rau kev ua haujlwm hydraulic thiab kev ncaj ncees ntawm cov kav dej. Cov qauv tam sim no siv Nominal Diameter (DN) raws li qhov tseem ceeb siv tsis tau rau cov yeeb nkab loj; Qhov no yog ua ke nrog Tus Qauv Dimension Ratio (SDR) los tswj cov phab ntsa tuab, thiab ntxiv dag zog ntxiv los ntawm Ring Stiffness (SN) kev faib tawm kom ntseeg tau tias muaj zog compressive. Qhov no multi-dimensional parametric moj khaum ua rau muaj qhov sib txuam ntawm lub siab-cov kev cai thiab kev teeb tsa ntawm ntau hom kev siv engineering.
