Could we request that the tanks be metalized before shipping? Is this something that is done commonly or would it be a special request and therefore difficult/expensive?
I am indirectly the end user of the tanks as the Proj Mgr/Facilities Eng.
We do have a NACE certified guy to do the metalizing at the site, but politics may prevent him from being able to do it. And there is no guarantee he will stay forever, either.
Otherwise, the contractor installing the...
I keep seeing reference in Specifications that contractors can substitute the peppermint test in lieu of the smoke test on plumbing systems.
No one seems to know exactly what the peppermint test is. Does anyone have an idea?
The following procedures for coating the outside of two CS tanks were recommended by a NACE certified paint specialist on a project:
1. Tanks shop primed at the factory for shipping.
2. Tanks will be sand blasted / blast cleaned to NACE 1 / SSPC 5 (2 mils)
3. Tanks will be metalized with...
Going back to the Saddles:
To answer MiketheEngineer, there are no signs of cracking, no signs of rebar expansion – one spot that is showing delaminating, but not on large scale and in a repairable location. Concrete does not fail silently - generally the signs are there well before it goes...
Just one more question:
If you repair a tank that has a interior coating for potable water, how do you restore that if it is disturbed in the welding process?
H57
Even the IBC is confusing. IBC 2006 3403.2.3.2 allows for an increase not to exceed 10% cummulative increase or 5% decrease in support capacity.
Either way, with the tanks being basically the same all around, I do not expect any increase in stress to the supports. It appears little has...
One tank is 25K gallons and the other is 5K gallons (hydro pneumatic).
The deterioration appears to be in the tanks, although it will not be clear until they are lifted out of the saddles. There was some weep-seep-reseal action going on previously, but it has stopped. There are no signs of...
I am replacing two existing potable water steel tanks supported on reinforced concrete saddles with two new tanks (same size, same diameter, just about the same everything) due to the age of the tanks and suspected deterioration around the saddles.
The saddles are in good condition and may...
I have to project to either replace or repair two water storage tanks: (1) a 25,000 gallon tank used to store post-filtered and pre-chlorinated water and (2) a 5,000 gallon tank post-chlorination hydro-pneumatic tank for distribution into a potable water system.
The tanks, believed to have...
Is there anything to contradict cutting a 1/2"-3/4" hole through a section of ASCE rail at 8'-0" centers for the length of the rail.
I believe the rails are ASCE 30 rails.
The intent is to provide drainage across a set of door rails and allow the water to move from one track to another and...
During a site walkdown for repairs to an existing helicopter hangar which includes the repair/replacement of the existing insulation, the following questions were asked:
1. Is the insulation is required?
2. And if not, should it be removed?
The hangar doors are open most of the time due to...
