Document Type and Number:
WIPO Patent Application WO/1998/011375
Kind Code:
A1
Abstract:
A stainless steel pipe (10) comes in three types, stainless steel pipes (10a, 10b, 10c) in which bellows portions (11) are bent to respectively provide a triangular shape, a trapezoidal shape, and a polygonal shape, and the respective stainless steel pipes (10a, 10b, 10c) are selected so as to be suitable for piping site requirements and combined with the bellows portions (11) bent at desirable angles to form various configurations of piping paths in a simple manner. Integrally secured to a straight pipe portion (12) on one end of the stainless steel pipe (10) through resin molding is an insulating sleeve (13) having a circumferential surface having a low friction coefficient to permit slide fitting, and a single-ended nipple (15) or a cap nut (24) is rotatably mounted on the outer circumference of the sleeve (13) while a means is provided for preventing the coming-off thereof.
