1. A pipe comprising a host pipe,a pipe liner, the pipe liner including a base pipe, the base pipe comprising a new pipe made of temperature-resistant non-metallic corrosion-resistant material, the base pipe having an outer surface, an inner surface, a first end and a second end and a flow channel therethrough from the first end to the second end,the base pipe comprising a plurality of individual pipe sections connected together,a first strengthening wrap around the base pipe,a second strengthening wrap around the base pipe,a plurality of spaced-apart axial strength members positioned on the base pipe,a protective outer wrap on the second strengthening wrap, andthe base pipe comprising a stand-alone replacement for use within a damaged host pipe,the base pipe having a wall thickness of between about 4 mm and 7 mm, andwithout the application of energy to the pipe liner before or after installation thereof in the host pipe. 2. The pipe of claim 1 wherein the plurality of individual pipe sections of the base pipe are welded together. 3. The pipe of claim 1 wherein the plurality of individual pipe sections of the base pipe are butt fusion welded together end-to-end using a fusion welding machine. 4. The pipe of claim 1 wherein each of the plurality of individual pipe sections is an extruded cylinder. 5. The pipe of claim 1 wherein the base pipe has a Standard Dimensional Ratio between 26 and 36. 6. The pipe of claim 1 wherein the pipe liner is of a continuous length produced in-situ at a site of a host pipe. 7. The pipe of claim 1 further comprising a plurality of sensors positioned on the base pipe that provide signals indicative of one of tension applied to the pipe, leaks of the pipe, movement of the pipe, and temperature along the pipe. 8. The pipe of claim 7, the pipe liner further comprising a third wrap to secure the axial strength members and sensors in place, anda fourth wrap to cover the third wrap. 9. The pipe of claim 1 wherein the first strengthening wrap and the second strengthening wrap are fabric material made of high strength synthetic fibers. 10. The pipe of claim 1 wherein the axial strength members are unidirectional tapes made of synthetic fibers. 11. The pipe of claim 1 wherein the protective outer wrap is one of adhesive backed thermoplastic tape, a sleeve of thermoplastic film, and a sleeve of HDPE film. 12. The pipe of claim 1 wherein the axial strength members are pulling tapes. 13. The pipe of claim 1 wherein the pipe and the pipe liner range in length up to 10 miles. 14. The pipe of claim 1 in which the base pipe has a Hazen-Williams coefficient between 150 and 160. 15. A method for making a pipe liner suitable for installation into a host pipe without the application of energy to the pipe liner before or after the installation, the method comprising welding together a plurality of pipe sections to form a base pipe, the base pipe comprising a new pipe, the base pipe comprising a temperature resistant non-metallic corrosion-resistant material made in-situ at a use site, the base pipe having an outer surface, an inner surface, a first end and a second end and a flow channel therethrough from the first end to the second end, the base pipe comprising a stand-alone replacement for use within a damaged host pipe, the base pipe having a wall thickness between about 4 mm and 7 mm,wrapping the base pipe with a first strengthening wrap,wrapping the base pipe with a second strengthening wrap,securing a plurality of axial strength members on the base pipe,deforming the base pipe to facilitate insertion thereof into a damaged host pipe, andwrapping the base pipe following deforming with a plurality of members to maintain the pipe in a deformed shape during insertion into a damaged host pipe. 16. The method of claim 15 wherein the welding is done by a fusion welding machine for butt fusion welding the pipe sections together end-to-end. 17. The method of claim 15 wherein each of the plurality of individual pipe sections is an extruded cylinder. 18. A pipe liner which is suitable for insertion into a host pipe, without the application of energy to the pipe liner before or after the insertion, the pipe liner comprising the pipe liner comprising a stand-alone continuous length high-pressure non-metallic liner produced in-situ at a site of a host pipe,the pipe liner comprising a plurality of individual pipe sections connected together, each section comprising an extruded cylinder,a base pipe comprising a plurality of pipe sections welded together, the pipe sections each being an extruded cyliner made of temperature-resistant non-metallic corrosion-resistant material, the base pipe comprising a new pipe, the base pipe having an outer surface, an inner surface, a first end and a second end and a flow channel therethrough from the first end to the second end,the base pipe having a wall thickness of at least 7 mm,the base pipe having a Standard Dimensional Ratio between 26 and 36,at least one strengthening wrap around the base pipe,a plurality of spaced-apart axial strength members positioned longitudinally on the base pipe,at least one fiber optic sensor on the base pipe for providing a signal indicative of one of tension applied to the pipe, leaks of the core pipe, movement of the pipe, and temperature along the pipe,a third wrap to secure the axial strength members and sensors in place,a fourth wrap on the third wrap,the pipe liner ranging in length up to 10 miles, andthe pipe liner made in-situ at a location of the host pipe,the base pipe comprising a stand-alone replacement for use within a damaged host pipe. 19. The pipe liner of claim 18 wherein the plurality of individual pipe sections are welded together. 20. The pipe liner of claim 18 wherein the plurality of individual pipe sections are butt fusion welded together end-to-end using a fusion welding machine. 21. The pipe liner of claim 19 wherein weld beads produced during welding of the individual pipe sections are removed. 22. The pipe liner of claim 21 wherein weld beads are removed from an inside of the pipe. 23. The pipe liner of claim 18 further comprising a protective outer wrap on the base pipe for protection during installation of the pipe liner.
