ABSTRACT:
A security splicing system of aligned pipes against an expansion and/or contraction thereof due to variations in temperatures, has a flange unit providing a stability and watertightness of a splice, and including a double flange with two identical fastening elements gripping an outer face of an end area of two previously spliced pipes with a watertight connecting flange, so that an accidental displacement of the watertight connecting flange is prevented in an event that dimensions of the end area of the pipes vary due to an expansion or contraction.
