Pipe section, pipe assembly, method for manufacturing a pipe section and pipe arrangment, and use of a pipe assembly

A pipe section for conveying oil and/or gas, the pipe section comprising:

• a support layer consisting of a metal base material, the support layer having:
• a length,
• an inner diameter,
• an inner surface,
• an outer surface, and
• at least two pipe section ends each having an end region and an intermediate region;
• a first coating consisting of a first metal coating material, the first coating being in each end region of the inner surface of the support layer, the first coating being welded to the support layer, and the first coating having a first thickness, a penetration depth, and a longitudinal extension;
• and
• a second coating consisting of a second metal coating material, the second coating being in the intermediate region of the inner surface of the support layer, and the second coating being sprayed onto the support layer using a thermal spraying process,
• wherein the support layer, on the inner surface, has a roughness Ra of more than or equal to 0.2 μm.

A method for manufacturing a pipe section, the method comprising steps of:

• providing a support layer consisting of a metal base material, the support layer having a length, an inner diameter, an inner surface, an outer surface, and at least two pipe section ends each having an end region and an intermediate region;
• roughening the support layer on the inner surface;
• applying a first coating in each end region of the inner surface of the support layer, using a laser deposition welding process;
• and
• applying a second coating in the intermediate region of the inner surface of the support layer, in particular using an arc spraying process.
