Abstract
A light weight filament wound pressure vessel for retaining gases under high pressure is formed with a barrier liner, in which the liner comprises a single layer of biaxially stretched and oriented polyethylene terephthalate (PET) plastic material.
Claims5
In a lightweight pressure vessel for retaining a gas under pressure, in which a liner forms a gas barrier for the vessel, and in which said vessel is strengthened by a wound filament as an over-wrap about said liner, the improvement comprising said liner being formed of a single layer bi-axially biaxially oriented polyethylene terephthalate material.
A lightweight, high strength, composite lined gas pressure vessel, comprising:
- a liner formed as a single thickness of biaxially oriented polyethylene terephthalate polymer material,
- said-liner having a polar generally hemispherical closed end, a generally cylindrical center section, and a generally semi-spherical inlet end in opposed relation to said closed end,
- an inlet boss pressure molded to said liner inlet end,
- said inlet boss having an annular skirt portion positioned against an outside surface of said liner at said inlet end, an axial end formed in said inlet boss defining an opening, and a portion of said liner integrally extending axially into said opening and defining an inside annular sealing surface for forming a seal with a sealing member carried on a coupler threaded into said inlet fitting opening.
