Određivanje mehaničkih svojstava umreženog polietilena
, 2020 Cijevi od umreženog polietilena (PE-X) mogu se koristiti umjesto cijevi od metalnih materijala pri izvođenju sustava za sanitarnu vodu ili grijanje. Pritom PE-X cijevi mogu nadoknaditi nedostatke metalnih cijevi poput slabe otpornosti na koroziju. U ovom radu prikazane su cijevi od umreženog polietilena sa stupnjem umreženosti većim od 70% (PE-Xa). Kao
