PROBLEM TO BE SOLVED: To provide a high-pressure joint in which an applicable diameter is from 25 mm to 3 m, and pressure resistance is 100 MPa at most, regarding an adhesion joint of an FRP (Fiber-Reinforced Plastic) pipe.SOLUTION: A connection surface has a 1/16 taper; a corrosion resistant layer only comprising resin is laminated on all surfaces contacting to leaked water liquid; a circumferential long fiber is laminated for a laminate on the innermost surface of a pipe body; a resin having resin single elongation of at least about 10% is used for a pipe; and a shear reinforcement pin is used as needed.SELECTED DRAWING: Figure 10 |
