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.
Claims14
A tank comprising:
- 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;
- a connection attached to each of the upper and lower domes in the through passages of the necks, the connections being the same as one another, each connection having a through passage with threads along an inner surface thereof for connection of attachments;
- a connector attached to each of the connections, each connector being sealed to an end of the neck of the respective upper or lower dome by a first seal and being sealed to another area of the neck by a second seal;
- and
- wherein the upper dome further comprises a lead-in that engages the first end of the polymeric shell and the lower dome further comprises a lead-in that engages the second end of polymeric shell, each of the lead-ins comprising a first portion, a second portion proximate the first portion, and a third portion proximate the second portion, the first portion oriented parallel to an outer surface of the polymeric shell, the second portion oriented radially inward from the polymeric shell at a first angle compared to the first portion to create a gap between the second portion and the polymeric shell, and the third portion oriented radially inward from the polymeric shell at a second angle compared to the first portion to create a gap between the third portion and the polymeric shell, wherein the second angle is greater than the first angle such that the gap between the third portion and the polymeric shell is greater than the gap between the second portion and the polymeric shell.

A tank assembly comprising:
- a tank including:
- a polymeric body defining a cavity and having an upper neck and a lower neck each defining a through passage in communication with the cavity, wherein the polymeric body includes a polymeric upper dome having the upper neck, a polymeric lower dome having the lower neck, and a polymeric shell having a first end connected to the upper dome and a second end connected to the lower dome,
- an upper connector being sealed to an end of the upper neck by a first seal and being sealed to another area of the upper neck by a second seal;
- a lower connector being sealed to an end of the lower neck by a first seal and being sealed to another area of the lower neck by a second seal, the lower connector having an inlet portion attached to the lower neck and a conduit portion extending from the inlet portion, the inlet portion and conduit portion each having a through passage fluidly connected with one another to direct flow from the cavity through the conduit portion;
- and
- a support stand supporting the tank,
- wherein the upper dome further comprises a lead-in that engages the first end of the polymeric shell and the lower dome further comprises a lead-in that engages the second end of polymeric shell, each of the lead-ins comprising a first portion, a second portion proximate the first portion, and a third portion proximate the second portion, the first portion oriented parallel to an outer surface of the polymeric shell, the second portion oriented radially inward from the polymeric shell at a first angle compared to the first portion to create a gap between the second portion and the polymeric shell, and the third portion oriented radially inward from the polymeric shell at a second angle compared to the first portion to create a gap between the third portion and the polymeric shell, wherein the second angle is greater than the first angle such that the gap between the third portion and the polymeric shell is greater than the gap between the second portion and the polymeric shell.

A tank comprising:
- a polymeric upper dome;
- a polymeric lower dome;
- a polymeric shell having a first end connected to the upper dome and a second end connected to the lower dome and forming with the upper and lower dome a cavity;
- a flexible diaphragm connected to an inner wall of the polymeric shell in the cavity;
- and
- a fiberwinding layer around an outer surface of the polymeric upper dome, polymeric lower dome, and polymeric shell,
- wherein the upper dome further comprises a lead-in that engages the first end of the polymeric shell and the lower dome further comprises a lead-in that engages the second end of polymeric shell, each of the lead-ins comprising a first portion, a second portion proximate the first portion, and a third portion proximate the second portion, the first portion oriented parallel to an outer surface of the polymeric shell, the second portion oriented radially inward from the polymeric shell at a first angle compared to the first portion to create a gap between the second portion and the polymeric shell, and the third portion oriented radially inward from the polymeric shell at a second angle compared to the first portion to create a gap between the third portion and the polymeric shell, wherein the second angle is greater than the first angle such that the gap between the third portion and the polymeric shell is greater than the gap between the second portion and the polymeric shell.
