Abstract

A pressure assembly including a cylinder, an end plug and a split ring band. The cylinder has an end, an inner surface and an outer surface. The end plug is inserted into the end of the cylinder, the end plug having an outer surface that is in partial contact with the inner surface of the cylinder. The split ring band is in contact with the outer surface of the cylinder, the split ring band being secured to the cylinder and to the end plug.

Claims (33)

1. A pressure assembly, comprising:

a cylinder having an end, an inner surface and an outer surface;

an end plug inserted into said end of said cylinder, said end plug having an outer surface that is in partial contact with said inner surface of said cylinder; and

a ring band in contact with said outer surface of said cylinder, said ring band being secured to said cylinder and to said end plug and said ring band including a plurality of holes therethrough;

said cylinder having a plurality of holes therethrough, said holes of said ring band being spaced similar to a spacing of said holes in said cylinder.

2. The assembly of claim 1 , wherein said cylinder is a reinforced polymeric composite cylinder including a reduced diameter portion on said outer surface to accommodate said ring band.

3. The assembly of claim 2 , wherein said ring band is at least partially disposed in said reduced diameter portion.

4. The assembly of claim 3 , wherein said ring band substantially fills said reduced diameter portion.

5. The assembly of claim 1 , wherein said cylinder includes an annular groove to accommodate positioning of said ring band therein.

6. The assembly of claim 5 wherein said cud plug includes a plurality of blind holes therein which substantially align with said plurality of holes in said cylinder.

7. The assembly of claim 6 further comprising a plurality of fasteners that utilize said holes in said band, said holes in said cylinder and said blind holes of said end plug to secure said band to said end plug.

8. The assembly of claim 1 , further comprising:

an other end plug; and

another ring band, wherein said cylinder has an other end into which said other end plug is inserted, said other ring band being in contact with said outer surface of said cylinder, said other ring band being secured to said cylinder and to said other end plug.

9. A fluid tight end of a cylinder assembly, comprising:

a tube having an inner shaped surface and an outer surface;

a plug having an outer surface shaped to compliment said inner shaped surface, said plug being placed in at least partial contact with said inner shaped surface; and

a band positioned on said outer surface of said tube, said band being secured to said outer surface of said tube and to said plug, said band including a plurality of holes therethrough,

said tube having a plurality of holes therethrough, said holes of said band being spaced similar to a spacing of said holes in said tube.

10. The assembly of claim 9 , wherein said tube being a reinforced polymeric composite tube including a reduced diameter portion on said outer surface to accommodate said band.

11. The assembly of claim 10 , wherein said band is at least partially disposed in said reduced diameter portion.

12. The assembly of claim 10 , wherein said band substantially tills said reduced diameter portion.

13. The assembly of claim 9 , wherein said tube includes an annular groove to accommodate positioning of said band therein.

14. The assembly of claim 13 , wherein said plug includes a plurality of blind holes therein which substantially align with said plurality of holes in said tube.

15. The assembly of claim 14 , thither comprising a plurality of fasteners that utilize said holes in said band, said holes in said tube and said blind holes of said plug to secure said band to said end plug.

16. The assembly of claim 9 , further comprising:

another plug; and

an other band, wherein said tube has an other end into which said other plug is inserted, said other band being in contact with said outer surface of said tube, said other split ring band being secured to said tube and to said other end plug.

17. A pressure assembly, comprising:

a cylinder having an end an inner surface, an outer surface and a plurality of apertures therethrough,

an end plug inserted into said end of said cylinder, said end plug having an outer surface that is positioned to lie near said inner surface of said cylinder; and

a band having a plurality of apertures and positioned to lie near said outer surface of said cylinder, said band being secured to said cylinder and to said end plug;

wherein said holes of said ring band being spaced similar to a spacing of said holes in said cylinder.
