Varec currently made by Tyco and Shand and Jurs both have “free vents” for which test data are available showing flow rates versus pressure I think Varec’s data is available online.

I guess the scariest part was that it could be 5 or worse more than 5 years before these defects can be observed though intermittent inspections, leaving breaches and corrosion to run their course The large roof surface area makes the vacuum loading quite extreme.
Depending on where the tank is located, cold weather comes into play. The Eng-Tips staff will check this out and take appropriate action.

I believe Greenheck does have some sort of frost-resistant vent, but not sure of the details.

awwq There are also allowances they recommend for insect screening blockage. Hi there, I am new to eng-tips and pretty excited about what I see so far. Typically, vents on water tanks are sized about the same size as inlets or outlets IE, same nominal pipe size. The damage I got to see was associated with vent structures that did not fail safe design vents Defense manufacturing is all about project manufacturing and project accounting.
