Taw qhia:
HDPE (High-Density Polyethylene) yeeb nkab fittings ua lub luag haujlwm tseem ceeb hauv ntau qhov kev lag luam vim lawv cov kev ua haujlwm siab zoo, ua haujlwm ntev, thiab ntau yam. Kab lus no muab cov ntsiab lus ntawm lub peev xwm siab thiab cov qauv tsim kev xav rau HDPE yeeb nkab fittings. Cov ntaub ntawv qhia ntawm no yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo thiab ua haujlwm ntawm HDPE kav dej.
1. Siab Peev Xwm ntawm HDPE Yeeb Nkab Fittings:
1.1. Kev faib khoom siv:
HDPE yeeb nkab fittings raug cais raws li lawv cov qib siab thiab cov khoom siv qib. Kev ntsuas siab txiav txim siab qhov siab tshaj plaws kev ua haujlwm siab (MAOP) ntawm cov fittings. Cov kev ntsuas siab tshaj plaws rau HDPE yeeb nkab fittings suav nrog PN4, PN6, PN10, PN16, PN20, PN25, thiab PN32, nrog PN sawv cev "Pressure Nominal" thiab tus lej qhia MAOP hauv cov tuav.
1.2. Qhov Loj thiab Phab Ntsa Thickness:
Lub peev xwm siab ntawm HDPE yeeb nkab fittings yog cuam tshuam los ntawm lawv qhov loj thiab phab ntsa tuab. Phab ntsa Thicker muab kev tiv thaiv zoo rau sab hauv thiab sab nraud. Nws yog ib qho tseem ceeb uas yuav tau xav txog qhov nominal txoj kab uas hla, sab nraud txoj kab uas hla, thiab phab ntsa thickness ntawm cov fittings thaum txiav txim siab lawv lub peev xwm.
2. Kev tsim qauv ntawm HDPE Yeeb Nkab Fittings:
2.1. Kev sib koom ua ke:
HDPE yeeb nkab fittings tuaj yeem koom nrog siv ntau txoj hauv kev, suav nrog pob tw fusion, electrofusion, socket fusion, thiab mechanical jointing. Kev xaiv ntawm txoj kev sib koom ua ke yog nyob ntawm yam xws li daim ntawv thov, txoj kab uas hla ntawm cov yeeb nkab, thiab qhov yuav tsum tau muaj zog sib koom ua ke. Cov txheej txheem sib koom ua ke thiab cov cuab yeej siv tau zoo yuav tsum tau siv los xyuas kom muaj kev sib txuas ruaj khov thiab tsis muaj paug.
2.2. Kev txhawb zog thiab kev txhawb nqa:
Nyob ntawm daim ntawv thov thiab kev ua haujlwm, HDPE yeeb nkab fittings yuav xav tau kev txhawb zog lossis kev txhawb nqa kom tiv thaiv cov khoom siv sab nraud thiab tiv thaiv deformation. Cov kev siv zog ntxiv xws li cov hlau ntxig, cov hlua khi, lossis cov hlua khi tuaj yeem txhim kho cov qauv kev ncaj ncees ntawm cov fittings thiab xyuas kom muaj kev xa khoom zoo.
2.3. Kev Ntsuam Xyuas Kev Nyuaj Siab:
Kev ntsuam xyuas kev ntxhov siab yog qhov tseem ceeb los ntsuas qhov kev ncaj ncees ntawm HDPE yeeb nkab fittings nyob rau hauv ntau yam kev ua haujlwm. Cov yam ntxwv xws li kev siab sab hauv, sab nraud loads, thermal expansion / contraction, thiab av kev sib haum xeeb yuav tsum tau txiav txim siab los soj ntsuam cov kev ntxhov siab tis thiab xyuas kom meej tias cov fittings muaj peev xwm tiv tau cov ntaub ntawv siv zog.

Kev nkag siab txog lub peev xwm siab thiab cov qauv tsim kev txiav txim siab rau HDPE yeeb nkab fittings yog qhov tseem ceeb rau lawv txoj kev xaiv, kev teeb tsa, thiab kev ua haujlwm. Los ntawm kev txiav txim siab txog kev faib khoom, qhov loj me, phab ntsa tuab, kev sib koom ua ke, kev txhawb nqa / kev txhawb nqa, thiab kev ntsuam xyuas kev ntxhov siab, cov kws tsim khoom thiab cov neeg tsim qauv tuaj yeem ua kom muaj kev nyab xeeb thiab ua haujlwm zoo ntawm HDPE kav dej. Nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov qauv kev lag luam, cov lus pom zoo ntawm cov chaw tsim khoom, thiab cov kev ua haujlwm engineering kom ua tiav cov kev daws teeb meem ruaj khov thiab ruaj khov siv HDPE yeeb nkab fittings.
