The present invention relates to a novel type of tubular insert 28 for connecting an extra-corporeal circuit 26 to a peristaltic pump 22. This tubular insert 28 comprises a loop 32 formed by a tube portion 20; the loop 32 comprises a curve 38 which extends around an axis X. The tube 20 which forms the curve 38 has an oval cross-section with a major axis M and a minor axis m perpendicular to each other, where the major axis M is longer than the minor axis m. Finally, in the tubular insert 28 according to the invention, the minor axis m of each cross-section of the tube 20 along the curve 38 is parallel to the axis X . The invention further relates to a method for producing the tubular insert 28 and to a peristaltic pump 22 suitable for operating with tubular inserts according both to the invention and to the prior art.

The invention relates to a supply tube (16') for a painting system, in particular for supplying compressed air to a turbine in a rotary atomizer or for supplying an atomizer with a fluid medium, such as paint or a rinsing agent, comprising an upstream tube section (20) and a downstream tube section (22). According to the invention, the upstream tube section (20) has a larger inner cross-section than the downstream tube section (22). The invention further relates to a painting robot with such a supply tube (16').

The invention relates to a flexible sleeve (1) arranged to be connected to at least one rigid duct (2a, 2b), said sleeve including at least one end arranged to be fitted onto an end of said duct. The end of the sleeve includes a peripheral groove (3a, 3b) formed in the inner surface thereof and arranged for receiving, when said end is slipped onto an end of said duct, a complementary peripheral bead (5a, 5b) arranged on the outer surface of said end, and the inner perimeter (4a, 4b) of said sleeve end is smaller than the outer perimeter (6a, 6b) of the end of said duct such that the reception of said bead in said groove and that the difference between the perimeter of the inner surface of said sleeve end and that of the outer surface of said duct end ensures a connection between said sleeve and said duct that is sealed to the material to be conveyed by the sleeve and the duct.

The invention relates to a flexible pipe comprising a plurality of layers surrounding a longitudinal axis and an at least partly integrated sensor arrangement. The plurality of layers comprising an internal sheath and one or more armouring layers, at least one armouring layer comprising at least one folded metal strip helically wound around said longitudinal axis of the pipe, at least a part of said sensor arrangement being placed in a fold of said folded metal strip, the sensor arrangement preferably comprises an optical fibre which is placed in the fold of said folded metal strip. By this flexible pipe with a sensor arrangement, the sensor arrangement may be incorporated into the armouring layer in a simple and safe way. The sensor arrangement may for example be capable of sensing at least one property, selected from the group of stress-strain, temperature, pipe leakage, wear, mechanical deformations, pressure, chemical corrosion, salt concentration of liquid in contact with the pipe and pH value of liquid in contact with the pipe.

The invention relates to a method for producing a system (10) for guiding and controlling the temperature of a urea/water solution, in which method at least one heating conductor (14) is wound around a section of a fluid line (12), and in which method at least one layer of polymer material (26) is wound around regions of the section, around which the heating conductor (14) has been wound, until the layer of polymer material (26) is wound around the section along the entire predefined length, in order to form a covering (16) of polymer material which surrounds the section, wherein the layer of polymer material (26) is produced by an extrusion process, and wherein the winding around the regions of the sections, around which the heating conductor (14) has been wound, is carried out before the layer of polymer material (26) is cured. Furthermore, the invention relates to an apparatus, in particular for carrying out the method.
摘要:
An ultra low permeability fluid member for conveying a fluid (e.g., a hose, tube, etc.) having a metal vapor barrier layer (22) formed around an inner tube (14). The metal vapor layer (22) is formed from one or more metal strips (40a, 40b) having edge portions (44) that are bonded so as to seal the vapor barrier layer (22) preventing permeation of vapor.
