METHOD FOR PRODUCING PIPING PARTS FOR HIGH PRESSURE AND PIPING PARTS FOR HIGH PRESSURE

摘要

PROBLEM TO BE SOLVED: To provide a method for providing piping parts for high pressure and the piping parts for high pressure produced with this producing method, wherein the allowance degree of pressure-resistance can be improved.;SOLUTION: This structural body 10 is formed with a closed forging and composed of a main body part 11 formed with a front part pressing-out formation and side arm parts 12, 13 formed with a side part pressing-out formation, and in the main body part 11, a fiber-flow 111 is formed along a flowing passage 14a by after-working, and in the side arm part 12, the fiber-flow 121 is formed along the flowing passage 14b. Therefore, since the energizing direction according to the impression of the inner pressure to the flowing passages 14a, 14b are almost orthogonal to the directions of the fiber-flows 111, 121, the allowance degree of the pressure-resistance of the body for injector can be improved.;COPYRIGHT: (C)2006,JPO&NCIPI
