Because of the various excellent characteristics of cast basalt materials,such as,anti-corrosion,anti-wearing,good hardness,high chemical stability,of which steel may not possess,the steel-basalt composite pipes are used in severe environments for compensating the defects of steel.The limit of bending moment with which steel-basalt composite pipe may safely endure was calculated and the limit curvature of the composite pipe in the safe range was presented.The application temperature of steel-basalt pipe was examined due to a different coefficient among basalt,mortar and mild steel.
