摘要
Abstract
Interference bonding is between the base pipe and the liner pipe of the mechanically lined pipe, and the liner pipe is relatively thin. If it is used unsuitably in the project, it is possible that buckling and instability would appear on the liner pipe of the bimetal lined pipe. Through the mechanism analysis on the buckling and instability of the liner pipe of the bimetal lined pipe, this paper indicates mechanical condition of the buckling occurrence on the liner pipe and the empirical formula, which is suitable for the critical load estimation on the liner pipe buckling. The principal factors that might influence the buckling of the lined pipe are analyzed according to the mechanical condition of the buckling occurrence, together with the design, production and using process of the lined pipe. Based on the theoretical analysis and empirical testing, this paper concludes that unreasonable design of the lined pipe structure and bonding strength between the base and liner pipe could lead to the reduction of the critical load of the liner pipe buckling. At the same time, the principal factors of the liner pipe buckling and instability are the water penetration between the base and liner pipe while using under high temperature, the appearance of penetrating defects on the liner pipe, which causes the transporting stuff to enter the gap between the base and liner pipe.关键词
