Abstract
A pressure vessel having a relief area onto which a flange of a side port can be attached. The relief area includes a planar mating surface raised from the cylindrical sidewall of the vessel. A method for forming the pressure vessel includes providing a cylindrical mandrel provided with a side port spacer. Fiberglass is wrapped onto the mandrel and space. The fiberglass is impregnated with resin and the resin is cured. A metallic insert ring is embedded in a full bore open end of the pressure vessel. The ring has a cross-section having a height to width ratio of less than 0.7.
Claims9
A pressure vessel comprising:
- a cylindrical side wall formed from resin impregnated reinforcing fibers;
- a generally cylindrical side port having an annular flange and an outside thread;
- a relief area onto which the flange can be attached, the relief area extending outward from the cylindrical side wall;
- a planar mating surface at an inside face of the relief area;
- and
- a threaded bore in the mating surface threadedly receiving the port and cooperating with the outside thread of the port.
