Sliding wear properties of neat polychlorotrifluoroethylene against SUS304 stainless steel surface, which are indispensable for predicting service life of gaskets used in the swivel-type joints on LNG loading arms, were investigated at the temperatures of the ambient (20℃) and LNG (-162℃). The effects of contact pressure, sliding speed and sliding distance on the amount of wear loss were analyzed by applying the Rhee-type wear equation. Through regression analysis, the Rhee-type wear equation for the stable sliding wear condition range was approximated as follow: (1) At the ambient temperature, 20℃: W_1=2.09X10^ <-7>P^ <2.35>V^ <3.38>t^ <1.44> PV<20MPa・mm/sec (2) At LNG temperature,-162℃: W_2=1.60X10^ <-12>P^ <1.05>V^ <3.50>t^ <2.29> PV<240MPa・mm/sec where W is the wear loss (mg/cm^2), P is the nominal contact pressure (Mpa), V is the sliding speed (mm/sec), t is the sliding time(min), and PV is the PV factor (Mpa・mm/sec).
