Abstract: Provided is an efficient preparation method of a bimetallic seamless composite pipe, and belongs to the technical field of steel pipe manufacture. The efficient preparation method of the bimetallic seamless composite pipe includes following steps: sheathing a base pipe blank on a cladding pipe blank to obtain a composite pipe blank, and carrying out a stress relief annealing treatment on the composite pipe blank, where the base pipe blank and the cladding pipe blank are made of different materials; heating the composite pipe blank after the stress relief annealing treatment to a hot working window temperature, and sheathing on a core rod of an extrusion cylinder after an insulation treatment, and then extruding along an axial direction of the extrusion cylinder to obtain a bimetallic seamless composite pipe.

Abstract: An inspection robot system, including one or more detection devices, a rail, a traction device, one or more connecting devices, and a multi-axis manipulator. The detection devices are configured to at least obtain environmental image information. The rail is suspended in an air. The traction device includes a steel cable and a steel cable drive assembly. The steel cable drive assembly is connected to the steel cable and is configured to drive the steel cable to move along an axial direction of the steel cable. The connecting devices are slidably connected to the rail. The detection devices are respectively arranged on the connecting devices. The connecting devices are connected to the steel cable and are configured to move along the rail under a traction of the steel cable. At least one of the connecting devices is/are each provided with the multi-axis manipulator.
