The material parameters of TiNiFe shape memory alloy were determined by experiments, and the constitutive model was established. The coupling force of the system of pipe-coupling and connected tube was simulated with raising temperature, and the influences of inner diameter, wall thickness and fit clearance of pipe-couplings were investigated. In order to improve the connecting strength, the wall thickness was properly increased, and the inner diameter and fit clearance should be decreased.
