Lub cev thiab txhua yam khoom ntawm cov yeeb nkab HDPE raug raws li hauv qab no:
• Cov qauv siv tau: ISO 1183, ISO 4427, AS/NZS 4130, BS EN 12201, EN 12056, AWWA C901, AWWA C906, thiab lwm yam.
• Muaj qhov loj me: DN 16 txog 1600 (qhov loj me tuaj yeem tsim tau)
• Qhov ceev ntawm HDPE yeeb nkab: 930 - 970 kg/m³
Cov khoom siv ntawm cov yeeb nkab HDPE raug pom nyob rau hauv cov lus hauv qab no. Txawm li cas los xij, cov txiaj ntsig no txawv nyob ntawm cov chaw tsim khoom, yog li nws yuav tsum tau sab laj nrog cov chaw tsim khoom.
