PURPOSE: A steel pipe joint for electric wire pipe is provided to perform easily a joint process by using an aluminium alloy material, a plastic material, a cast iron material, and a cast steel material. CONSTITUTION: A body is shaped by using an aluminium alloy material, a plastic material, a cast iron material, and a cast steel material. A fitting bolt(4) is used for fixing a steel pipe(9) for electric wire pipe. A rubber packing(3) is used for preventing a clogging phenomenon of the steel pipe(9) due to cement water in a concrete process. A steel socket(1) for electric wire pipe is used for connecting the steel pipes(9) for electric wire pipe arrangement to each other. In a process for connecting a normal band with the steel pipe(9) for electric wire pipe arrangement, the steel pipe(9) for electric wire pipe arrangement and a normal band are inserted into both insertion holes of the steel socket(1) for electric wire pipe arrangement.
