Generally from the course of corrosion-resistant FRP pipe has been developed as an alternative material of the corrosive metal pipe, combination with existing metal flange is required. Basically, by mating surfaces unified, common commercialization can be achieved. So, after standards of PCD/ hole diameter of the bolt, a flange inner and outer diameters are defined, from the specifications of unevenness of the flange contact surface, waterproof function, applied bolts/number, and the allowable pressure, product design is carried out.
