<p>The invention relates to a pipe section for insulation of pipes, consisting essentially of mineral wool which contains at least a binder and possibly also other additives, and to a method for manufacturing the same. In the method, a block (1) of cured pipe section, emerging from the production line and consisting essentially of mineral wool which contains at least a binder and possibly also other additives, is brought to its final shape by cutting off its uneven ends. At least a part of cut-off ends (2) of the section blocks (1), along with all materials contained therein, are reused in at least one previous manufacturing stage of said blocks of pipe section by adding the same on top of and/or to a still uncured mineral wool material (3).</p> |
