Abstract: The invention relates to a device (1) for measuring the surface condition of a component (4, 5, 6). Said device (1) comprises a measurement member (2) comprising at least one sensor (21, 22, 23) capable of measuring at least one datum relating to the surface condition of the component (4, 5, 6) and at least one transmitter (24) capable of transmitting the datum from the sensor (21, 22, 23). The measurement device (1) also comprises a support (3) for the measurement member (2), the support comprising means for connecting same to the component (4, 5, 6).

Abstract: The invention relates to a method for checking, prior to welding, two components made of polymer material, the method comprising a step of determining respective values relating to the roughness of the components, a step of determining respective values relating to the cleanliness of the components, a step of determining respective values relating to the temperature of the components and automated means for halting progression to a subsequent method step should the predetermined conditions not be met.

Abstract: The invention relates to a nondestructive testing device for detecting possible thickness anomalies (Ve) of a wall (P), this device comprising a sensor (1) including means (11) for emitting and receiving ultrasonic waves, and acoustic coupling means (2). The sensor according to the invention comprises a rigid enclosure (12, 13) sealingly defining a free internal volume (10), and the coupling means (2) comprise a solid coupling body (21) belonging to the enclosure, and a coupling liquid (L) disposed in the free internal volume (10) and in which the emitting and receiving means (11) soak.

Abstract: A method of repairing in situ a pipe or tank of thermo-fusible material, with a step for installing an electric heating element, the heating element including electrical conductors, and with a step for supplying said conductors with appropriate electric energy. The electrical conductors are supplied by a control panel set up prior to the repair and matching, for different thermo-fusible materials and different types of damage of the pipe or tank to be repaired, at least one technical characteristic of the pipe or tank, one characteristic of the electric energy to be applied and a profile of the application time of the electric energy.

Abstract: The invention relates to a device and a method for welding two polymer parts via fusion using a heater mat knitted from a resistive wire coated with an insulating varnish, the heater mat being given a final shape. The heater mat is resistive wire having a diameter ranging from 0.2 mm to 0.3 mm, and has approximately parallelepiped meshes, the dimensions of which range from 1.5×3 mm2 to 2.5×4.5 mm2.

Abstract: The invention concerns an identification process that makes it possible to confer traceability to manufactured products (PROD), from data of origin (C, D) initially brought together at a source point (P_SOURCE) and including a control identification number (C) and manufacturing data (D) common to these products (PROD). The process of the invention provides for the formation of two parallel information flows, (?1 and ?2), each of which ensures a propagation of the data of origin (C, D) in time and space from the source point (P_SOURCE), and includes three tests (COMPAR—1, COMPAR—2, COMPAR—3) that makes it possible to verify the internal consistency and integrity of these data of origin in the form in which they are propagated.
