Description

This invention relates to a field of winding collars for connecting bypass conduits or devices such as pressure sensors or temperature sensors to a main pipeline. In particular, the present invention relates to a winding device intended to be mounted on a pipeline opening, comprising at least one clamp collar having a diameter adaptable to several pipeline diameters. In particular, the present invention makes it possible to adapt the winding device in place to several types of existing pipelines. Numerous devices exist to form bypasses on the main pipeline, connecting to other conduits or devices such as measuring sensors. Conventional bypass devices, also known as "bypass collars," or even "winding collars," traditionally consist of a rigid base intended to be positioned in a sealed manner on the main pipeline, facing the bypass orifice. For this purpose, the base may have, for example, a lower section intended to penetrate into the orifice. A seal may also be positioned between the base and the pipeline orifice. The bypass device further includes a flexible flange that cooperates with the base to hold the base on the conduit. US reference 4, 435, 476 discloses a bypass device having an elbow-shaped tubular section. One end of the elbow has a circular seal positioned so that the end of the elbow protrudes below the seal. This end is intended to be inserted into the orifice of the main pipeline. The seal, having a diameter larger than the diameter of the orifice, is intended to rest on the pipeline to seal the orifice. The flange is formed by a circular collar with a central opening. The collar is inserted around the tubular section to place the collar on the seal. Thus, when the collar is closed around the pipeline, it compresses the seal against the pipeline orifice. However, this system cannot accommodate several types of devices on the pipeline. In fact, the collar's opening has a fixed diameter, which limits the shape and dimensions of the additional equipment. Specifically, the equipment must have a portion with a diameter smaller than or equal to the collar's opening to allow the collar to slide along the pipeline, and a portion with a diameter larger than the opening to allow the collar to hold the equipment against the pipeline. Reference FR 2 933 764 describes a bypass device comprising a saddle with a through-opening including threads, which allows for the screwing in of a bypass pipe. The saddle also comprises means for fastening a flexible strip. The fastening means includes a through-opening at one end of the saddle, allowing the flexible strip to be inserted and locked by a tongue. The other end of the saddle has a rotating metal rod system for winding up the flexible strip. The ends of the rod and strip are provided with openings for receiving screws that, on the one hand, prevent the rod from rotating, and on the other hand, hold the strip on the rod. This system has asymmetrical means for securing the flexible strip, complicating the installation of the device on the pipeline. Furthermore, the manufacture of such a device is extremely complex and expensive.
