FIELD: chemical engineering. SUBSTANCE: second body in the form of the first layer which has first and second main surfaces is placed on first body. Second main surface of second body is brought in contact with main external surface of first body. This done, bodies being coupled are subjected to irradiation in wavelength range of infra-red radiation. Tube is used as first body. After second body is superposed on tube third body in the form of second layer is laid on. Second layer is applied on first layer. When layers are irradiated two adjacent main surface of first and second layers are heated up to welding temperature, thus coupling them by melting. In addition, superposition of first layer on tube and second layer on first one is performed by winding the layers under tension. Direction of winding of first layer on tube is opposite to direction of winding of second layer of first one. Material, structure of layers and their positioning on tube surface, as well as description of tube manufactured by given method are given herein. EFFECT: enhanced tube manufacturing process. 8 cl, 2 dwgr |
