Title:
RESIN PIPING AND MANUFACTURING METHOD FOR THE SAME
Document Type and Number:
Japanese Patent JP2017001318
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To easily suppress a variation in the welded strength between a first case and a second case depending on the areas.SOLUTION: A resin piping 12 includes an outside case and an intermediate case 30 joined to the outside case. At least a part of junctions 29A, 29B, 29C, 39A, 39B, 39C of the outside case and the intermediate case 30 is extended by being superimposed on projection planes of bottom surfaces 311, 321, 331 of gasket grooves 31, 32, 33 formed on the back surface of the intermediate case 30 projected along a direction orthogonal to the bottom surfaces 311, 321, 331. Also, wall thicknesses between the bottom surfaces 311, 321, 331 of the gasket grooves 31, 32, 33 in the intermediate case 30 and the junctions 29A, 29B, 29C, 39A, 39B, 39C are designed to be uniform.SELECTED DRAWING: Figure 9
