Stainless nitrogen storage tank are too large to be put together inside a shop facility and transported to the project site. Profession-Built nitrogen storage tank, on the other hand, can be fabricated, blasted, primed and built in a shop and then transported to the project site, where they are erected or installed. Sometimes shop built tanks are installed inside a building and sometimes they're installed outside. Like field erected welded steel tanks, shop built tanks can be made of carbon or stainless steel, and can meet various tank standards and codes, including ASME codes for pressure vessels. Volume and the dimensions of the tank, as well as pressure and code requirements, generally dictate whether a field erected tank or shop tank is needed. Occasioanally, the site will be the major factor. For example, we recently worked on a project that required a fairly small tank inside a building. The tank would normally be a shop-built tank, but because of limited access to the building, the tank needed to be erected on site, inside the building.
