摘要: An elongated product is formed such that first a core is formed, the outer surface of the core being made of plastic. Thereafter, a tubular metal layer is extruded such that the layer is seamless. When the metal layer is extruded, a clearance is allowed between the metal layer and the core. After the metal layer has cooled, the diameter of the metal layer is reduced such that the metal layer contacts the plastic core. Thereafter, the metal is annealed such that the flexibility of the metal layer increases.

摘要: The invention relates to a method for producing a strand-shaped part, wherein a hollow section (16) of metal is extruded, the extruded metal hollow section (16) cools and/or is cooled, and a plastic strand (28) having one or more layers is extruded into the extruded metal hollow section (16) after or during cooling. The plastic strand (28) passes by a dispensing tool (24), exposed to the heat of the extruded metal hollow section (16) of an extruder (34). The dispensing tool is inserted into the metal hollow section (16) and comprises a dispensing outlet (26), which is disposed inside a region of the metal hollow section (16) in which the dispensing tool is cooled in relation to the temperature thereof during extrusion.

摘要: 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”.

摘要: The heating and/or sanitation pipe comprises an inner pipe (12) made of a plastic material and a metal corrugated pipe (14) surrounding the inner pipe (12) at a radial distance {circle around (R)}). Further, the heating and/or sanitation pipe is provided with a compressible and/or expanded material (16) between the inner pipe (12) and the corrugated pipe (14) for fixing the inner pipe (12) inside the corrugated pipe (14). The compressible and/or expanded material (16) is adapted to be detached from the inner pipe for the purpose of exposing a connecting end of the inner pipe (12). Further, the heating and/or sanitation pipe comprises an insulation layer (18) surrounding the metal corrugated pipe (14) and an outer covering (20) around the insulation layer (18).

摘要: A screw joint for pipes, in particular sanitary and floor heating pipes of, for example, plastic material or a composite material of metal and plastics is provided with at least one screw joint member with a substantially cylindrical portion, in which a thread with at least one helical raised portion of, in particular, triangular cross section is formed. The at least one raised portion of the thread has a base section adjoining or located in the cylindrical portion and an end section radially adjoining the base section. Within at least a part of the course of the thread, at least the end section of the at least one raised portion is made of a material that is more elastic than the material of the cylindrical portion.
