The pre-insulated pipe section includes a pipe and a thermal insulation layer of rigid foam molded to surround the pipe. The pre-insulated pipe section having fasteners made of rigid material fixedly connected to the insulation layer as integral parts for connecting the pre-insulated pipe section to another structure. ## Claims ### Claim 1 A plumbing arrangement comprising a pre-insulated pipe section, the pre-insulated pipe section comprising a pipe and a thermal insulation layer of rigid foam molded to surround the pipe, wherein the pre-insulated pipe section comprises fasteners made of rigid material fixedly connected to the insulation layer as integral parts for connecting the pre-insulated pipe section to another structure, wherein the fastener comprises a baseplate comprising perforations which form passageways for the uncured foam during molding for securing the baseplate to the rigid foam, when cured, and a fastening member arranged to the baseplate for connecting the pre-insulated pipe section to another structure. ### Claim 2 (depends on 1) The plumbing arrangement according to claim 1, wherein the fasteners are made metal of metal or rigid plastics. ### Claim 3 (depends on 1) The plumbing arrangement according to claim 1, wherein the fasteners are partly embedded in the insulation layer. ### Claim 4 (depends on 1) The plumbing arrangement according to claim 1, wherein the fasteners are bonded with an adhesive on the outer surface of the insulation layer. ### Claim 5 (depends on 1) The plumbing arrangement according to claim 1, wherein the fasteners are bonded with a double sided tape on the outer surface of the insulation layer. ### Claim 6 (depends on 1) The plumbing arrangement according to claim 1, wherein the fasteners are bonding fasteners. ### Claim 7 (depends on 6) The plumbing arrangement according to claim 6, wherein the fastening member comprises a hole in the baseplate. ### Claim 8 (depends on 7) The plumbing arrangement according to claim 7, wherein the fastening member comprises a nut connected to the baseplate coaxially with the hole. ### Claim 9 (depends on 8) The plumbing arrangement according to claim 8, wherein the nut is a rivet nut. ### Claim 10 (depends on 6) The plumbing arrangement according to claim 6, wherein the fastening member comprises a screw fixedly connected to the baseplate. ### Claim 11 (depends on 10) The plumbing arrangement according to claim 10, wherein the screw is a rivet screw connected to the baseplate. ### Claim 12 (depends on 1) The plumbing arrangement according to claim 1, wherein rigid foam of the insulation layer is expanded polyurethane (PUR) or expanded polypropylene (EPP) or expanded polystyrene (EPS) or expanded polyisocyanurate (PIR). ### Claim 13 (depends on 1) The plumbing arrangement according to claim 1, wherein the pre-insulated pipe section comprises at least two fasteners arranged at a distance from each other along the length of the pre-insulated pipe section. ### Claim 14 (depends on 1) The plumbing arrangement according to claim 1, wherein the pre-insulated pipe section comprises a plurality of fasteners arranged at a distance from each other in a row along the length of the pre-insulated pipe section. ### Claim 15 (depends on 14) The plumbing arrangement according to claim 14, wherein the pre-insulated pipe section comprises at least two rows of fasteners. ### Claim 16 A plumbing arrangement comprising a pre-insulated pipe section, the pre-insulated pipe section comprising a pipe and a thermal insulation layer of rigid foam molded to surround the pipe, wherein the pre-insulated pipe section comprises fasteners made of rigid material fixedly connected to the insulation layer as integral parts for connecting the pre-insulated pipe section to another structure, wherein the plumbing arrangement comprises a prefabricated installation module having mounting means for mounting in a room of a building to form continuous vertical plumbing lines together with other similar installation modules, the installation module comprising the pre-insulated pipe section, and a frame made of metal and having an inner space into which the pre-insulated pipe section is installed and supported to the frame with said fasteners. ### Claim 17 (depends on 16) The plumbing arrangement according to claim 16, wherein the frame comprises a support member comprising a counterpart configured for connection to the fastener. ### Claim 18 (depends on 17) The plumbing arrangement according to claim 17, wherein that the support member is movably connected to the frame. ### Claim 19 (depends on 1) The plumbing arrangement according to claim 1, wherein the plumbing arrangement comprises a push fitting connected to an end part of the pipe protruding outside from the insulation layer of the pre-insulated pipe section. ### Claim 20 (depends on 19) The plumbing arrangement according to claim 19, wherein the plumbing arrangement comprises an extension insulation section made of rigid foam and arranged in abutment with the pre-insulated pipe section, the extension insulation section having an external dimension (d) conforming to the an external dimension (d) of the pre-insulated pipe section, and an inner channel having an inner dimension adapted to receive the push fitting therein, the extension insulation section comprising two section halves having connecting elements for detachably connecting the section halves together. ### Claim 21 (depends on 20) The plumbing arrangement according to claim 20, wherein the connecting elements are selected from the group: a hook and loop fastener, double-sided tape, a spike, a cable tie, a tongue
