Definitions
- a further preferred embodiment of the method for producing a multilayer pipe by means of a bending roll according to the present invention is characterized in that at least one of the material layers consists of more than one applied element, preferably more than one sheet.
- the laid-up elements can lie with their longitudinal edge parallel to the longitudinal edge of the underlying material layer, but need not. So it is also possible that they come to rest with their longitudinal edge transverse thereto.
- This method is particularly suitable for making large diameter, preferably larger than 610 mm (24 ") multilayer pipes of the invention where often the width of available inner layer material strips, preferably steel strips, is insufficient to provide a complete inner layer for such large If two tapes are not sufficient, the process can be continued as desired: three or more elements, preferably metal sheets, are then placed on top.
- the multilayer pipe is closed by welding the outer pipe along the Rorhrnaht and build-up welding of the inner tube, so as to manufacture the multilayer tubular body.
- the material layers can be connected to the front sides of the tube, such as there to prevent the ingress of moisture between the metallurgically yes not fully connected material layers.
- a preferred application of the method according to the present invention is the production of double-layer tubes according to the invention, however, the invention is not limited thereto, also three-, four- and more multi-layer pipes according to the invention are hereby basically produced, which is far more difficult according to the prior art if not impossible at all.
- sheets preferably metal sheets and more preferably steel sheets, as a material layer or elements of the material layer use.
- FIG. 2 shows a perspective sketch of two successive layers of material to be combined with the multilayer pipe, with a first connection, preferably welding between the material layers approximately along a (imaginary) line parallel to a longitudinal edge of the overlying material layer.
- 3 is a perspective sketch outlined in perspective on two superposed to multilayer pipe material layers to be combined, in which case one of the material layers of two launched in the tube longitudinal direction elements - preferably sheets - is,
- Fig. 10 is a perspective cross-section through a multilayer pipe according to the present invention, where the base plate of the outer tube has stop edges and the inner tube forming inner plate is clamped according to the deformation progress between these stop edges
- FIG. 6 shows a perspective sketched perspective view of an inventive multi-layer pipe 5 from one end side during the manufacturing process according to the invention, namely in the process step, where after a certain deformation progress at least one other compound - here two other compounds - 6a and 6b, here in each case as a continuous or partially executed weld, between the material layers 1, 2 was created by the fact that the overlying material layer 1 at least one other position - were connected together - here at two other positions.
