Experimental Research on the Mechanical Parameters of Frozen Pipes under Low Temperature

Abstract:

We carried out experiments of the mechanical properties of frozen pipes under different temperatures (-5°C, -10°C, -15°C), obtained axial tensile stress - strain curves of the steel and performance of the overall bending under low temperature conditions. The results showed that: the freezing pipes bending capacity increased with the decrease of temperature, but the stiffness was decreased with the decreasing temperature; the steel yield strength and ultimate strength were both increased with the decrease of temperature, the elongation and sectional shrinkage were decreased with the decrease of temperature. The test results provided the basis for the further research of frozen pipes’ ductile-brittle transition, fracture and other acts in low temperature, and provided reference for the selection of frozen pipe and engineering design.
