Abstract
Provided is a tank including a polymeric upper dome having a neck with a through passage, a polymeric lower dome having a neck with a through passage, a polymeric shell having a first end connected to the upper dome and a second end connected to the lower dome, and a connection attached to each of the upper and lower domes in the through passages of the necks, wherein the upper dome, lower dome, and shell form a cavity.
Claims13
A tank comprising:
- a polymeric upper dome having a neck with an inner surface defining a through passage;
- a polymeric lower dome having a neck with an inner surface defining a through passage;
- a polymeric shell having a first end connected to the upper dome and a second end connected to the lower dome;
- a polymeric connection connected to each of the upper and lower domes in the through passages of the necks, the connections being the same as one another and each connection having a body and a flange portion extending from the body, the body having an outer surface that abuts the inner surface of the respective neck and an inner surface defining a through passage with threads for connection of attachments, and the flange portion being received in a corresponding area in the respective upper and lower dome, each corresponding area being an annular pocket having an upper and lower surface;
- and
- a fiberwinding layer around an outer surface of the polymeric upper dome, polymeric lower dome, and polymeric shell,
- wherein the upper dome, lower dome, and shell form a cavity, and
- wherein the through passage of the upper dome is in communication with the cavity and the through passage of the lower dome is in communication with the cavity.

An assembly for a tank comprising:
- a polymeric upper dome having, a first end, a second end, a neck at the second end having an inner surface defining a through passage, and a lead-in proximate the first end of the upper dome and having an annular base;
- a polymeric lower dome having a first end, a second end, a neck at the second end having an inner surface defining a through passage, and a lead-in proximate the first end of the lower dome and having an annular base;
- a polymeric shell having a first end and a second end and being configured to be connected to the polymeric upper and lower domes to form a cavity, wherein an end face of the first end of the shell is configured to abut the annular base of the lead-in of the polymeric upper dome and an end face of the second end of the shell is configured to abut the annular base of the lead-in of the polymeric lower dome;
- and
- a flexible diaphragm configured to be connected to an inner wall of the polymeric shell in the cavity,
- wherein each neck includes a radially outwardly extending annular rib along its outer surface, each radially outwardly extending annular rib including a plurality of circumferentially spaced flats.
