不適とされる。However, since the above-mentioned sanitary joint 7 is a technique which has been used for a sanitary electromagnetic flow meter used in the dairy industry and the like where the fluid pressure is relatively low, it is suitable for high pressure fluids. Had the problem of being unsuitable. That is, in large plants with long and complicated pipes as seen in beer relations, etc., when installing in a place where the pipe size is large and the fluid pressure is high, the pipes and electromagnetic flow meters themselves also become large and heavy. , Twisting, bending, compression due to expansion and contraction of the pipe due to temperature change around the pipe, tensile stress, and vibration of the pipe cannot be ignored, and as a result, the lap joint 2 and the flange portion 5a
There has been a problem that the fluid to be measured leaks due to the displacement of the joint portion with, the displacement of the pipe, the deformation, the damage of the gasket, and the like. Therefore, in order to prevent such a problem, the number of fixing points of the pipe has been increased more than ever, and the pipe work has been carried out to press it firmly, but a radical solution has not been reached. That is, the connection structure using the clamp joint 7 has a weak fastening force and is unsuitable for a large-scale plant with high fluid pressure.
