High-density polyethylene yeeb nkab muaj nuj nqis los ntawm kev lag luam pipeline rau nws cov khoom siv tshuaj zoo heev, toughness, hnav tsis kam, tus nqi qis thiab kev teeb tsa. Nws yog qhov thib ob nkaus xwb rau polyvinyl chloride thiab qhov thib ob feem ntau siv cov khoom siv yas yeeb nkab; High-density polyethylene yeeb nkab (HDPE) ob-phab ntsa corrugated yeeb nkab yog ib hom yeeb nkab uas tsis siv cov khoom siv, siab rigidity, zoo heev yooj, corrugated sab nrauv phab ntsa thiab du sab hauv phab ntsa. Piv nrog rau cov kav dej zoo tib yam ntawm tib qhov tshwj xeeb thiab lub zog, cov kav dej ob phab ntsa tuaj yeem txuag tau 40 feem pua ntawm cov ntaub ntawv, thiab muaj cov yam ntxwv ntawm kev ua haujlwm siab thiab kev ua haujlwm siab, thiab txhim kho sai. Daim ntawv thov thaj chaw: dav siv los ua cov kav dej, cov kav dej phwj, cov kav dej hauv av, cov kav dej ua liaj ua teb thiab cov kav dej.
Hla-txuas polyethylene yeeb nkab yog suav tias yog ib tiam tshiab ntawm cov yeeb nkab ntsuab vim nws txoj kev tu cev zoo thiab kev siv tshuab thiab lub cev muaj zog. Cov yam ntxwv tseem ceeb yog tsis muaj xeb, zoo tshuaj corrosion kuj; ruaj khov kev ntxhib los mos thiab siab tsis kam mus rau sab hauv siab; qis nro ntawm cov phab ntsa hauv cov yeeb nkab, uas tuaj yeem tiv thaiv nplai; du sab hauv phab ntsa ntawm cov yeeb nkab, me me dej ntws tsis kam, hydraulic zog zoo heev. Daim ntawv thov teb: Nws tuaj yeem siv rau hauv kev tsim cov dej txias thiab kub, haus cov kav dej, cua sov hauv pem teb thiab dej cua sov, thiab lwm yam.
