Abstract:
The present invention relates to a method of manufacturing a seamless multilayer composite pipe, an apparatus for manufacturing a seamless multilayer composite pipe, and a seamless multilayer composite pipe. The method of manufacturing a seamless multilayer composite pipe comprises the steps of a) providing a seamless metal pipe with at least one continuous layer covering its inner surface, and b) passing the seamless metal pipe through a unit in order to reduce the diameter of the seamless metal pipe by cold working. An apparatus for manufacturing a seamless multilayer composite pipe comprises a unit for providing a seamless metal pipe with at least one continuous layer covering its inner surface, and a unit for reducing the diameter of the seamless metal pipe by cold working. A seamless multilayer composite pipe comprises a seamless metal pipe with at least one continuous layer covering its inner surface, wherein the continuous layer covering the inner surface of the a seamless metal pipe is mechanically compressed.
