Multi-layered pipes, machines for forming multi-layered pipes, and methods of forming multi-layered pipes, such as for use in the hydrocarbon industry as may form high-pressure pipelines including forming an inner metal tube from a first metal stock, and while forming the inner metal tube, forming at least a second metal tube around the inner tube from at least a second metal stock. In some methods, sheet metal is bent to form tubes having seams, which are welded while the tubes are being formed. Some methods are performed proximate to an installation site for the multi-layered pipe, such as a hydrocarbon extraction or transportation site. Some methods are performed on a vehicle and proximate to an installation site.

The method of claim 3, wherein the inner metal tube has an outer surface, wherein the second metal tube has an inner surface, and further wherein the outer surface of the inner metal tube tightly rests against the inner surface of the second metal tube. 5. The method of claim 1, wherein the bending the first sheet metal includes feeding the first sheet metal through an inner-tube die, and wherein the bending the second sheet metal includes feeding the second sheet metal through a second-tube die. 6. The method of claim 1, further comprising: while forming the inner metal tube, inspecting the at least one inner-tube seal and inspecting the at least one second-tube seal. 7. The method of claim 1, wherein the joining the at least one inner-tube seam includes welding the at least one inner-tube seam to form the at least one inner-tube seal, and wherein the joining the at least one second-tube seam includes welding the at least one second-tube seam to form the at least one second-tube seal. 8. The method of claim 1, further comprising: while forming the inner metal tube, applying a coating to one or more of at least one side of the first sheet metal, at least one side of the second sheet metal, at least one of an inside and an outside of the first metal tube, and at least one of an inside and an outside of the second metal tube. 9. The method of claim 8, wherein the coating includes one or more of a paint, an adhesive, a glue, a cement, an epoxy, a lubricant, a polymeric, a thermal insulating material, an electrical insulating material, a material adapted to distribute stress, and a material adapted to protect against corrosion. 10. The method of claim 1, further comprising: while forming the inner metal tube, forming a third metal tube around the second metal tube from a third metal stock fed from a third metal supply. 11. The method of claim 1, further comprising: while forming the inner metal tube, positioning a preformed intermediate material between the inner metal tube and the second metal tube. 12. The method of claim 11, wherein the intermediate material between the inner metal tube and the second metal tube is non-metallic. 13. The method of claim 1, wherein the multi-layered pipe has an outer diameter greater than 150 mm. 14. The method of claim 1, wherein the multi-layered pipe has a thickness greater than 10 mm. 15. The method of claim 1, further comprising: ceasing the forming of the inner metal tube and ceasing the forming of the second metal tube when a length of the multi-layered pipe is greater than or equal to a predetermined length, wherein the predetermined length is at least 100 times an outer diameter of the multi-layered pipe. 16. The method of claim 1, wherein the multi-layered pipe is configured to withstand an internal pressure of at least 3.45 MPa. 17. The method of claim 1, wherein the multi-layered pipe is formed proximate to an installation site for the multi-layered pipe. 18.
