초록 ▼

A self-supporting pipe rupture and whip restraint system (10) for a process fluid pipe (12) of a nuclear reactor steam generator pressure vessel (14) includes a guard pipe (26) concentrically disposed about the process pipe (12) so as to entirely encase the process pipe (12) from the pressure vessel nozzle 18 to a terminal end fitting component (36) disposed exteriorly of the reactor facility building wall (32), the guard pipe (26) being integrally fixed to the process pipe (12) through means of the nozzle (18) and the component (36). Under postulated rupture conditions of the process pipe (12), pipe whipping of the process pipe (12) is restrained by the guard pipe (26), and the process fluid effluent from the process pipe (12) is contained within the guard pipe (26). Leak detection apparatus (50) is operatively associated with the annular space (30) defined between the process pipe (12) and the guard pipe (26) so as to detect ruptures or fractures within either the process pipe (12) or the guard pipe (26). The provision of a 90°elbow bend section (52) within the system also facilitates thermal expansion of the process pipe (12) relative to the guard pipe (26) without requiring conventional expansion joints or expansion bellows.

대표청구항 ▼

A pipe rupture and whip restraint system, comprising: first pipe means for conveying a fluid within an area to be protected from whipping of said first pipe means in response to a pipe rupture condition which can occur at any axial position along the longitudinal extent of said first pipe means within said area to be protected; and second pipe means, concentrically disposed about said first pipe means in a radially spaced fashion so as to define a free annular space between said first and second pipe means into which said fluid can enter under said pipe rupture condition and having its opposite ends integrally fixed to the opposite ends of said first pipe means such that said ends of said first and second pipe means are joined together to form single-piece, unitary structures whereby said first pipe means will be entirely encased within said second pipe means in a fluid-tight and load-bearing manner, for withstanding dynamic load forces attendant a rupture of said first pipe means, for containing said fluid within said annular space defined between said first and second pipe means, and for physically and stably restraining the whipping of said first pipe means within said second pipe means under said pipe rupture condition of said first pipe means by permitting said fluid to enter said annular space defined between said first and second pipe means.
