CHARACTERIZATION OF POLYETHYLENE RESINS AND GAS PIPE. PHASE 2. CORRELATIONS. FINAL REPORT, SEPTEMBER 1986-FEBRUARY 1989
The chemical properties of commercial polyethylene natural gas distribution pipe were measured. These properties included molecular weight averages and distribution, crystallinity, density, type and concentration of molecular branches on the polymer chain. The mechanical behavior of these pipes was evaluated in constant tensile load (CTL) tests that covered a wide range of applied stress. The CTL test data were fit to a bilinear model that provided parameters reflecting the long-term test behavior of the pipes.
