Purpose: The article describes influence of temperature on friction coefficient of low density polyethylene in the aspect of loads occurring in a drawing die during free drawing of pipes. Design/methodology/approach: Research was conducted on the basis of the PN-EN ISO standard. Findings: The paper presents results of friction coefficient research. The research was conducted on a testing machine with a special design table for measurement of friction in different, set temperatures. The paper resulted in characteristics of correlation between examined friction coefficient and temperature. Research limitations/implications: Research on dependence allows to evaluate thickness of the plasticized layer in free drawn PE pipes. Thickness of the plasticized layer depends on the value of friction coefficient. This is important in case of after-deformation returns which allows tight fitting of polyethylene lining during digless pipe reconstruction. Practical implications: Results of conducted research allow to verify the mathematical model describing a process of free pipe drawing. Originality/value: Research was conducted on exclusively prepared samples, which allows to reproduce conditions inside a drawing die.
