1. A pressure vessel comprising: a pipe comprising a proximal end, a distal end, a proximal tapered pipe section at the proximal end, a distal tapered pipe section at the distal end, a cylindrical pipe section between the proximal tapered pipe section and the distal tapered pipe section, an outer surface, and a bore that extends through the pipe from the proximal end to the distal end, and the bore having a first diameter in the cylindrical pipe section, and a proximal end diameter of the bore at the proximal end is smaller than the first diameter, and a distal end diameter of the bore at the distal end is smaller than the first diameter; and the outer surface of the pipe comprises a two-axis wound filamentous composite;a plug in the bore at the proximal end and the distal end, each plug comprising a cylindrical plug section, the cylindrical plug section being innermost in the bore and being contiguous with a cylindrical wall section, the cylindrical wall section being a section of the wall surrounding the bore in the cylindrical pipe section, and a tapered plug section being contiguous with the wall surrounding the bore in the proximal or distal tapered pipe section, the tapered plug section comprising an inward taper and the tapered plug section terminating in a surface located at or near the proximal or distal end of the pipe;wherein: the cylindrical plug section comprises a circumferential groove in which is disposed a seal;a compression cap at each of the proximal end and the distal end of the pipe, each compression cap comprising a tapered cap section, an inner surface of the tapered cap section being contiguous with an area of the outer surface of the proximal or distal tapered pipe section;wherein at 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 thermoplastic polymer. 6. The pressure vessel of claim 4, 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 tapered section 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, and the flange being at the end of the tapered plug section at or near the proximal or distal end 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 first diameter of the cylindrical section of the pipe is 18 inches or less. 12. The pressure vessel of claim 1, wherein the first diameter of the cylindrical section of the pipe is 6 inches or less. 13.

The pressure vessel of claim 13, wherein the filamentous composite comprises a matrix polymer. 15. The pressure vessel of claim 1, comprising an adhesive layer between the cylindrical surface of the plug and the cylindrical wall section. 16. The pressure vessel of claim 1, wherein the compression cap is fabricated of a material selected from the group consisting of a metal, an alloy, a polymer, a polymeric composite and a combination of these. 17. The pressure vessel of claim 1, wherein the fluid comprises a gas, a liquid or a combination thereof. 18. The pressure vessel of claim 4, wherein the liner comprises a ceramic. 19. The pressure vessel of claim 4, wherein the liner comprises a thermoset polymer. 20. The pressure vessel of claim 1, wherein the filamentous composite comprises a glass filament, a ceramic filament, a carbon filament, an aramid filament, a natural filament, an ultra-high molecular weight polyethylene filament, or a combination thereof. 21. The pressure vessel of claim 20, wherein the filamentous composite comprises a matrix polymer. 22. The pressure vessel of claim 21, wherein the matrix polymer comprises a thermoset polymer. 23. The pressure vessel of claim 22, wherein the thermoset polymer comprises an epoxy resin. 24. The pressure vessel of claim 22, wherein the thermoset polymer comprises a polyester. 25.
