Abstract: The fire protection system is for two or more supply lines (10), especially supply lines (10) mounted on a route (16) or a rack (18). The supply lines (10) are entirely surrounded by an isolating layer (12) made of a non-flammable or hardly combustible insulating material while a hollow space (15) is embodied between the supply lines (10) and the isolating layer (12). An insulating layer (14, 24) comprising an intumescent insulating layer-forming agent or an ablation is applied to the inside and/or outside of the isolating layer (12) to create a fire protection system for supply lines which ensures sufficient functionality of the supply lines even when space is limited.

Abstract: An agent and method for manufacturing a fire protection element on the basis of polyurethane foams from a polyol component and a diisocyanate component, the polyol component containing at least one phosphorus-containing polyol and wherein the polyol component and the diisocyanate component do not contain any borate.

Abstract: The method for protecting a pipe and/or cable lead through from heat and/or fire by providing a heat and/or fire retardant sealing for a pipe and/or cable passageway using a dimensionally stable, deformable fire protection element using an elongate fire protection element which is laid in the pipe and/or cable passageway, the elongate fire protection element being arranged transverse to the pipeline or to the cable.

Abstract: Metal-plastic multilayer pipe with a plastic inner pipe (30) and a metal sheath (32) around the plastic inner pipe (30), where the metal sheath (32) is of uniform thickness, is applied to the plastic inner pipe (30) so that it completely encircles the plastic inner pipe (30) and a practical plastic outer layer (38), with the feature that the thickness of the metal sheath (32) as compared to the total thickness of all layers of the multilayer pipe (32, 34 and 38), is sufficiently thin that the metal sheath (32) accounts for a negligible part of the overall strength and stiffness of the multilayer pipe and, as a consequence, when the multilayer pipe is bent in an arc, the metal sheath (32) offers negligible resistance to such bending as compared to the resistance offered by the inner pipe (30) and the practical cover layer (38), and when so bent, the multilayer pipe tends to remain bent in said arc, whereby, the multilayer pipe has “form stability”.

Abstract: Apparatus for bending pipes, particularly plastic or composite pipes, includes a chucking fixture for anchoring the pipes near the bending region, a bending template, the profile of which is made to fit the pipe cross section, and a bending cylinder which, in turn, has a profile that is made to fit the pipe cross section and is supported by a provided lever which, during a pivoting motion of the bending cylinder, is moved on a graduated circle about the bending template and runs concentrically to the surface of the bending template. In order to achieve easy manipulation, the apparatus is constructed as a manually operated device and parts of the apparatus are disposed on a mounting plate which is provided with a hand lever as a back-stop and which has a pivoted lever in the form of a hand lever for the bending cylinder.
