摘要： A method of assembling tubular heat exchangers and particularly of expanding tubes in the tube walls of various heat exchangers and steam generators in the petrochemical, gas-processing, chemical, power, metallurgical and shipbuilding industries including the manufacture of nuclear power plants for ships, of nuclear power stations and related products. According to the method the measuring of a force parameter or variable is effected simultaneously with the measuring of a linear parameter or variable of the expanding successively at three areas, viz. the area of elastic deformation of the tube, the area of plastic deformation of the tube up to the engagement of the tube with the surface of the opening in the tube wall, and the area of elastic deformation of the tube wall.

摘要： Apparatus for assembling tubular heat exchangers and particularly for expanding tubes in the tube sheets of various heat exchangers and steam generators in the petrochemical, gas-processing, chemical, power, metallurgical and shipbuilding industries including the manufacture of nuclear power plants for ships, of nuclear power stations and related products. A rolling tool acts to expand the tubes and measurement of a force parameter or variable is effected simultaneously with the measuring of a linear parameter or variable of the expanding successively at three areas, viz. the area of elastic deformation of the tube, the area of plastic deformation of the tube up to the engagement of the tube with the surface of the opening in the tube sheet, and the area of elastic deformation of the tube wall. Intermediate the tool and its drive is a device for measuring the linear variables of the expanding, and a device for measuring the force variable, the devices being operatively connected with an input of a computer whose output is connected through a control unit with the drive, for selective deenergization and reversing of this drive.
