The present invention provides a Type 3 pressure vessel comprising a polar boss that is attached to a metallic liner and provides reinforced static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance of the liner orifice or neck region. In particular, the material
The present invention provides a Type 3 pressure vessel comprising a polar boss that is attached to a metallic liner and provides reinforced static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance of the liner orifice or neck region. In particular, the material of the polar boss has higher static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance relative to that of the liner material.

1. A metal lined composite overwrapped pressure vessel comprising: (a) a liner constructed from a metallic material and comprising: (i) a liner orifice;(ii) a liner neck region surrounding said orifice and having an outer surface comprising a male threaded element; and(iii) a liner polar region surrounding said liner neck region;(b) a polar boss constructed of a second material, wherein said polar boss comprises: (i) a polar boss neck region having an inner surface comprising a complementary female threaded element, wherein at least a portion of the inner surface of said polar boss neck region is attached to at least a portion of the outer surface of said liner neck region by having at least a portion of said male threaded element engaged to at least a portion of said complementary female threaded mechanism, and wherein at least a portion of said female threaded element is adapted for direct connection to a port fitting device;(ii) a passage within said polar boss neck region that is coaxially aligned with said liner orifice; and(iii) a polar boss annular flange that extends radially outward from said polar boss and covers at least a portion of said liner polar region and is adapted to transfer the internal pressure load to a composite overwrap, wherein said second material has static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance greater than that of said metallic material; and(c) composite overwrap contacting at least a portion of said liner and said polar boss annular flange. 2. The pressure vessel of claim 1, wherein said metallic material comprises aluminum, aluminum alloy, copper, titanium, steel alloy, or a combination thereof. 3. The pressure vessel of claim 2, wherein said second material comprises steel, a ceramic, a metal alloy, steel, steel alloy, titanium, aluminum alloy, brass, beryllium, a ceramic, a composite material, or a combination thereof. 4. The pressure vessel of claim 1, wherein said polar boss is attached to said liner by a mechanical connection. 5. The pressure vessel of claim 1, wherein said polar boss is attached to said liner by an adhesive. 6. The pressure vessel of claim 1, wherein the diameter of said liner orifice is at least 2 inch (50 mm). 7. The pressure vessel of claim 1 further comprising a bladder that is inserted into said liner. 8. The pressure vessel of claim 7, wherein said pressure vessel is configured for use as a hydraulic accumulator. 9. The pressure vessel of claim 1 further comprising a port fitting device connected to said polar boss, wherein said port fitting device is a valve, a housing for poppet valve, a nozzle, a plug, a regulator, a pressure sensor, a temperature sensor, a pressure relief device or an telematics instrument to monitor the health of the pressure vessel. 10. A method for reinforcing a neck region of a composite overwrapped pressure vessel that comprises a liner constructed of a metallic material and comprising: a liner orifice;a liner neck region surrounding said liner orifice and comprising an outer surface that comprises a male threaded element; anda liner polar region surrounding said liner neck region, said method comprising:engaging the male threaded element of the outer surface of the liner neck region with a complementary female threaded element in an inner surface of a polar neck region of a polar boss that is constructed from a second material having a greater mechanical strength than that of said metallic material, thereby providing a stronger mechanical strength within the liner neck region of said composite overwrapped pressure vessel compared to the same pressure vessel in the absence of said polar boss, wherein said polar boss comprises a polar boss flange that extends radially outward from said polar boss; andcontacting at least a portion of said liner and said polar boss annular flange with a composite overwrap. 11. The method of claim 10, wherein at least portion of said liner and said polar boss is overwrapped with a composite material. 12. The method of claim 10, wherein at least a portion of said liner neck region is securely fitted into an orifice of said polar boss neck region. 13. The method of claim 10, wherein at least a portion of said polar boss neck region is securely fitted into an orifice of said liner neck region. 14. A metallic-lined composite overwrapped pressure vessel comprising: (a) a liner constructed from a metallic material and comprises: a liner orifice;(ii) a liner neck region surrounding said orifice and having an outer surface comprising a male threaded element that is configured to securely attach a polar boss; and(iii) an inner liner polar region surrounding said liner neck region;(b) a polar boss constructed from a second material having a static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance greater than that of said metallic material, wherein said polar boss comprises: (i) a polar boss neck region having an inner surface comprising a complementary female threaded element that is configured for securely attaching to the male threaded element that is present on the outer surface of said liner neck region, wherein the engagement of said male threaded element to said complementary female threaded element prevents a relative movement between said liner and said polar boss;(ii) a passage within said polar boss neck region that is coaxially aligned with said liner orifice and said liner neck region; and(iii) a polar boss annular flange that extends radially outward from said polar boss and contacts at least a portion of an inner surface of said liner polar region, and(c) composite overwrap contacting at least a portion of said liner and said polar boss annular flange. 15. The metallic-lined composite overwrapped pressure vessel of claim 14, wherein said polar boss is removably attached to said liner. 16. The metallic-lined composite overwrapped pressure vessel of claim 14 further comprising: (i) a second liner orifice that is distal to said liner orifice;(ii) a second liner neck region surrounding said second liner orifice and having an outer surface with an engagement element configured to securely attach a second polar boss; and(iii) an outer liner polar region surrounding said second liner neck region; and(b) a second polar boss constructed from a material having a static strength, fatigue strength, endurance, chemical resistance and/or corrosion resistance greater than that of said metallic material, wherein said second polar boss comprises:(i) a second polar boss neck region having an inner surface with an engagement element configured for securely attaching to the engagement element of the outer surface of said second liner neck region, wherein the engagement element on the inner surface of said second polar boss neck region is securely attached to the engagement element of the outer surface of said second liner neck region;(ii) a passage within said second polar boss neck region that is coaxially aligned with said second liner orifice and said second liner neck region; and(iii) a second polar boss annular flange that covers at least a portion of an outer surface of said second liner polar region. 17. The metallic-lined composite overwrapped pressure vessel of claim 16, wherein said liner orifice and said second liner orifice are on the opposite ends of said pressure vessel.
