Title: Welded double-walled tube and method for its manufacture
Inventor: BAILLET RAYMOND
IPC: B21C37/06
Filed: 1985-03-07
Granted: 1987-12-17
Abstract: The double-wall welded tube has two portions of the tube, in the region of which the weld (10) is located, which are each defined by the outer surface of a fold (6, 7) formed by the material constituting, in this region, the double wall of the tube. In this way, the regin in which the weld is effected is perfectly homogeneous and the weld can therefore be of very high quality.

Abstract: Methods and apparatus for determining the relative proportions of intermixed constituents of a multiphase fluid system. The constituents for which relative proportions are being measured must have measurably different electrical permittivities. The systems use at least one electrically conductive probe (20) having two conductors (21, 22) which are spaced apart and capable of receiving the fluid system therebetween. Time domain reflectometers (40) present a stimulating time varying electrical signal to the probes and receive and measure reflected signals generated at impedance changes in the transmission line and probe. The probe transit time and/or associated average probe velocity provide a measure of the fluid system conditions which can be compared to predetermined values corresponding to various relative proportions of the intermixed constituents. A measure of the relative portions of the constituents is thus provided. The variability of individual probe transit velocity data can be measured, analyzed and used to measure fluid system turbulence. Relevant data can also be interpolated, extrapolated and integrated to provide profiling of the fluid system conditions and a means of total system inventory of the constituents.
