Typically, vents on water tanks are sized about the same size as inlets or outlets IE, same nominal pipe size. Click Here to join Eng-Tips and talk with other members! An HVAC engineer could probably point you to this info fairly easily.

The tank is comprised of 5 bands with full-pen welds at the seams between the bands and also at the individual segments making up each band. The tanks are being constructed one after the other with the same welders. I calculated that we have a total of about LF of weld. We are using Section The other interpretation is that the tests should be performed as the work progresses and one test is to be taken in each LF of weld as the work progresses or progressed.

Does anyone have enough experience with this code to say or know? Can you help us understand in a way that will convince the opposite party the interpretation provided is accurate?

Thanks much. The first sentence of RE: AWWA D Radiograph Test Location Interpretation OP 16 Dec 14 So, do you mean that the first test should be taken as soon as possible, but tests would still need to be performed as work progresses 1 per LF of weld , or do you read it as all of the tests can be performed at that first level of scaffolding or below?

This allows for proper corrective action as needed and prevents the need for compromising repairs if they have to be done later. The key is to perform the inspection as the tank is being constructed, not after construction is complete.

It is not economical to stop work to wait for the radiography subcontractor unless contractually obligated to do so. It is certainly not economical to call out a crew to perform a single shot.

It has been adopted by the American National Standards Institute as best practices within the industry for designing and building tanks to be used in water systems. If you are looking to have a water tank built, your custom metal fabricators must be familiar with the AWWA D Standard to ensure safety and security of the tank. Typically tanks are designed based on the intended volume of water that they will be storing. From there, the engineer can figure out the optimal diameter and sidewall height to achieve this goal. AWWA D tanks are typically assembled on site, and can be mounted on an oiled sand base, a concrete foundation, or even the roof of a building. The intended location of the tank can have a large impact on the dimensions of the tank being designed. In this case, carbon steel is the primary material for the tank itself.

AWWA Standard for Welded Carbon Steel Tanks for Water Storage Scope The purpose of this standard is to provide guidance to facilitate the design, manufacture, and procurement of welded carbon steel tanks for the storage of water. This standard does not cover all details of design and construction because of the large variety of sizes and shapes of tanks. Where details for any specific design are not given, it is intended that the constructor, subject to the approval of the purchaser, shall provide details that are designed and constructed to be adequate and as safe as those that would otherwise be provided under this standard. Details that are not addressed shall be designed and constructed to be adequate and as safe as those that would otherwise be provided under this standard. And this standard does not cover concrete—steel composite tank construction. Section 1 was revised to show the latest edition of references. Section 3 was revised to match the wind exposure definitions of ASCE
