CONSTITUTION: A sleeve for connecting a steel pipe comprises a cylindrical body unit(11) and an inclined surface. The external diameter of the cylindrical body unit is identical to the internal diameter of the steel pipe and an inner side is hollow. One end of the inclined surface is tapered to an inner side from the front end of the cylindrical body unit. The inclined angle is 20-45 degrees. |
