Abstract

Umreženi polietilen visoke gustoće je materijal nove generacije. Razvoj ovog materijala u industriji cijevnih sustava te njegova upotreba u građevinarstvu ukazuje na želju za napretkom i konstantu potragu za boljim i otpornijim materijalima s kojima bi se unaprijedio način građenja. Kratica za umreženi polietilen je PE-X. Cijevi na kojima je stavljen naglasak u ovom radu su cijevi oznake PE-Xa sa stupnjem umreženosti polietilena većom od 70%, koje su proizvedene Engelovim procesom ekstrudiranja. U ovom radu istražen je proces proizvodnje i primjena cijevi od PE-Xa materijala te je napravljen proračun cijevi u računalnom programu UPONOR HSE 4.5 na konkretnom primjeru obiteljske kuće. Također je provedeno eksperimentalno istraživanje na tri serije uzoraka različitih cijevi dostupnih na tržištu s ciljem određivanja granice popuštanja, vlačne čvrstoće, modula elastičnosti i produljenja pri lomu prema HRN EN ISO 6259-3:2015.

Abstract (english)

Cross-linked high-density polyethylene is a new generation material. The development of this material in the piping industry and its use in construction indicates a desire for progress and a constant search for better and more resistant materials in order to improve the way of building. The abbreviation for cross-linked polyethylene is PE-X. The pipes that are emphasized in this paper are pipes designated PE-Xa with a degree of crosslinking of polyethylene greater than 70%, which are produced by the Engel process of extrusion. In this paper, the process of production and application of pipes made of PE-Xa material is investigated, and a calculation of the piping system is made in the software UPONOR HSE 4.5 for a specific family house. An experimental study was also performed on three series of test specimens of different pipes available on the market with the aim of determining the yield strength, tensile strength, modulus of elasticity and elongation at break according to HRN EN ISO 6259-3:2015.
