1. A pressure vessel, comprising: a pipe having a proximal end, a distal end, a cylindrical section comprising a two-axis wound filamentous composite, a wall that defines a bore, the bore having an inside diameter in the cylindrical section, and a length that, together with the inside diameter, defines a volume, and the pipe having an outer surface; whereineach end of the pipe is inwardly tapered such that a diameter of the bore at each end of the pipe is smaller than the inside diameter;a plug in the bore at each end of the pipe, each plug comprising a cylindrical section at its proximal end, the cylindrical section being innermost in the bore and contiguous with a section of the wall of the pipe in the cylindrical section of the pipe and an inwardly tapered section at it distal end that is contiguous with the wall of the tapered section of the pipe, the tapered section of the plug terminating in a surface located at or near the end of the pipe; wherein:the cylindrical section of the plug includes a circumferential groove in which is disposed a seal;a compression cap at each end of the pipe, each compression cap having an inner surface, and each compression cap comprising a cylindrical section that is disposed over and contiguous with a portion of the outer surface of the cylindrical section of the pipe and a tapered section, the inner surface of the tapered section of the compression cap being contiguous with the outer surface of the tapered section of the wall of the pipe; whereinat least one of the plugs comprises a threaded port for fluid ingress and egress. 2. The pressure vessel of claim 1, where the angle at which the filamentous composite is wound is about 5° to about 85° in relation to a center line of the pipe. 3. The pressure vessel of claim 2, wherein the angle at which the filamentous composite is wound is about 20° to about 85°. 4. The pressure vessel of claim 1, wherein the pipe comprises a liner. 5. The pressure vessel of claim 4, wherein the liner comprises a material selected from the group consisting of a thermoplastic polymer, a thermoset polymer, a ceramic, a metal and combinations of these. 6. The pressure vessel of claim 5, wherein the liner comprises a metal. 7. The pressure vessel of claim 6, wherein the metal liner has been subjected to autofrettage. 8. The pressure vessel of claim 1, wherein the distal end of the plug comprises a flange extending orthogonally outward from a centerline of the plug for a distance that is the same or slightly less than the thickness of the wall of the pipe. 9. The pressure vessel of claim 1, wherein the taper of the plug and of the compression cap is inward at an angle of 5° to 45°. 10. The pressure vessel of claim 1, wherein the taper of the plug and of the compression cap is inward at an angle of approximately 10°. 11. The pressure vessel of claim 1, wherein the inside diameter of the cylindrical section of the pipe is 18 inches or less. 12. The pressure vessel of claim 1, wherein the inside diameter of the cylindrical section of the pipe is 6 inches or less. 13. The pressure vessel of claim 1, wherein the filamentous composite comprises a filament selected from the group consisting of a glass filament, a ceramic filament, a carbon filament, an aramid filament, a natural filament, an ultra-high molecular weight polyethylene filament and combinations thereof. 14. The pressure vessel of claim 13, wherein the filamentous composite comprises a matrix polymer. 15. The pressure vessel of claim 14, wherein the matrix polymer is a thermoset polymer. 16. The pressure vessel of claim 15, wherein the thermoset polymer is selected from the group consisting of epoxy resins, polyester resins, vinyl ester resins, polyimide resins, dicyclopentadiene resins, and combinations thereof. 17. The pressure vessel of claim 1, wherein the plug is fabricated of a material, the material being a metal, an alloy, a polymer, a polymeric composite or a combination of these. 18. The pressure vessel of claim 17, wherein the cylindrical surface, the tapered surface or both the cylindrical and tapered surface of the plug is knurled. 19. The pressure vessel of claim 1, comprising an adhesive layer between the cylindrical surface of the plug and the inner surface of the cylindrical section of the wall of the pipe. 20. The pressure vessel of claim 1, wherein the compression cap is fabricated of a material, the material being a metal, an alloy, a polymer, a polymeric composite or a combination of these. 21. The pressure vessel of claim 1, wherein the fluid comprises a gas, a liquid or a combination thereof.
