摘要

This flexible piping element is of the type consisting, essentially, of a segment of corrugated tube (4) housed in a tubular segment of external braid (5), these two segments (4, 5) being joined to one another at their ends by crimping and/or welding of the tubular segment of braid (5) onto a smooth end part (4a) of the segment of corrugated tube (4), a stop ring (6) surrounding the cylindrical end (5b) of the tubular segment of braid (5) level with this join. The segment of corrugated tube (4) has, at each of its ends, at least one deployed corrugation (7a), that is to say one whose pitch is made greater than that of the other corrugations (7). IMAGE
