FIELD: method of joining of two pipes of the same diameter from reinforced thermoplastics material. SUBSTANCE: method includes butt welding of pipe ends along weld over circumference. After formation of weld, external sleeve is installed on it with sleeve extended beyond weld sides over end sections of both pipes. External sleeve is heated and joined with pipe end sections. Applied to external sleeve of reinforced thermoplastic material is radial pressure. Pressure is applied until structures of reinforcing pipes and external sleeve come in contact with mutual penetration of external sleeve and end sections of two pipes. EFFECT: reliable joint of pipes, prevention of their separation caused by axial loads. 13 cl, 7 dwg
