Title: Inside surface plated copper pipe
Inventor: WATANABE MASAHITO
IPC: F16L58/04
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To improve the peeling resistance and corrosion resistance of the inside surface coating layer of a copper pipe by forming an Ni coating layer of a specific film thickness on the inside surface of the inside surface plated copper pipe and further forming an Sn coating layer of a specific film thickness on this Ni coating layer. SOLUTION: This inside surface plated copper pipe is obtd. by forming the Ni coating layer 2 having 0.1 to 20μm film thickness on the inside surface of the copper pipe 1, then forming the Sn coating layer 3 having 0.2 to 3μm film thickness thereon. The Ni of the inside surface plated copper pipe has a high adhesion property not only to Cu but to Sn as well and, therefore, the Ni coating layer 2 adheres sufficiently to both of the inside surface of the copper pipe 1 and the Sn coating layer 3 foamed above and below the same. Both of the Ni coating layer 2 and the Sn coating layer 3 are, therefore, hardly peelable from the inside surface of the copper pipe 1.  The double coating layers are formed by the formation of the Sn coating layer 3 on the Ni coating layer 2 and since there are the fewer plating pinholes to be the cause for the occurrence of corrosion, the better corrosion resistance is obtd.

IPC: G01F1/66
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To improve the precision by providing a transmitter for oscillating an ultrasonic wave out of a measuring pipe line, a reflecting plate for reflecting the ultrasonic wave on the measuring pipe line inner wall, and a plurality of receivers for receiving the ultrasonic wave out of the measuring pipe line. SOLUTION: An ultrasonic wave transmitted from an ultrasonic oscillator 11 provided on the outer wall of a measuring pipe line 1 is emitted into a measuring fluid Flo through a pad 12. The emitted ultrasonic wave is advanced vertically to the flow of the measuring fluid Flo, reflected by an ultrasonic reflecting plate 13, and also detected by a receiver 16. The ultrasonic wave reflected by the reflecting plate 13 is reflected vertically to the directions of average flow velocity paths B and C and reflected to the transmitter 11 in the direction of an acoustic velocity measuring path F. Consequently, the acoustic velocity can be measured by the path F, the flow velocity of the measuring fluid Flo can be measured by the average flow velocity paths B, C, and the flow velocity can be thus precisely measured.  Since the transmitter 11 and the receivers 14, 15, 16, 17 are provided on the outer wall side of the measuring pipe line 1, no complicated seal structure is required, and the cost can be thus reduced with high reliability.
