Abstract
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.
