ABSTRACT:
The method of manufacturing polymetallic pipes according to the invention consists of preparing the contacting surfaces of pipe billets, sealing off the gap between the billets at their ends and forming a multilayer pipe billet, heating said billet, placing it into a die and sealing off the space of the pipe billet, and filling said space with a fluid medium for exerting pressure on the internal surface of the billet, said pressure being sufficient for producing a diffusion joint.
According to the invention, the temperature gradient in the body of the pipe billet is distributed so that the temperature at one end of the billet is lower than it is in its other parts.
