Abstract
A means for thermal maintenance of industrial pipe by virtue of a working medium passing through at least one prefabricated hollow element attachable to the outside surface of the pipe wall is disclosed. The hollow element comprises an outer cover defined by an inner portion, facing the external surface of the pipe wall, an outer portion, situated opposite the inner portion and facing outwardly and transition portions connecting the inner portion with the outside portion. The inner portion is provided with concave configuration defined by radius R1 and closely matching the curvature of the pipe. The inner portion encloses about 180 degrees of the pipe's external surface and the transition portions are rounded by radius r, wherein r<R1.
