Abstract

Abstract: In order to evaluate pipeline reinforcing effect with glass fiber composite material, cylinder tube with thinned defects was prepared. The test results showed that the defect area determined the reinforcing area of composite materials. As the border width of reinforcing composite materials is more than 80% of the defect of the axial length, the composite performance was fully played when pipeline blasting. Through reasonable design, the short-time burst pressure of reinforcing steel tube was more than 30MPa. At that time, the fatigue number of composite reinforcing steel pipe was greater than 15000 times.

Key words: pipeline repair, burst pressure, fatigue number
