    6. The maximum allowable working pressure is 0.5 PSIG as measured from the top of the tank.
  2. API 620 tanks: 
    1. For liquid products with high internal pressure (up to 15 PSI) or low temperature.
    2. Application examples are liquified natural gas and cryogenic products.
    3. Aboveground, vertical tanks are usually larger than 300 feet in diameter and are field-erected due to their size.
  3. API 650 tanks: Low-Pressure Liquid Storage Tanks
    1. For liquid products that have lower pressure, but a higher temperature (up to 200oF).
    2. Application examples are oil, gas, chemicals, water, and biofuel.

Bulk Tank Sizes

We can fabricate tanks in any size capacity of up to 30 million gallons. Depending on shipping constraints, all tanks up to 20’ wide and 20’ tall may be built in our state-of-the-art facility. For larger tanks, we fabricate pieces or subassemblies in our shop and put them together on-site during the installation process.

High-Quality Materials

T BAILEY, INC.’s heavy manufacturing processes mainly use the highest quality carbon steel plate, or stainless steel where required. Our precision welding and specialized coatings allow us to produce steel tanks of excellent durability that can withstand extreme conditions.

Tank Head Assembly and Geometry

We offer welded or bolted end closures. The 3 most commonly used tank heads are:

  1. Elliptical or semi-elliptical. These are used on unfired pressure vessels, such as liquefied petroleum gas and air receivers.
  2. Hemispherical. These are used on large-circumference tanks or high-pressure applications to reduce material and weight.
  3. Flat. These are used in storage or holding tanks with no pressure. They are also a good option when you need a lower head height installation.

Other options include ASME flanged and dished, conical, and torispherical tank heads.

Our Bulk Storage Tank Fabrication Process

Step #1: After receiving the raw steel plate, we check every piece for quality and integrity.

Step #2: The steel is cut, beveled, and rolled into pieces that fit together to produce the correct diameter and height.

Step #3: The sections are welded together, either in our fabrication facility, or field erected on the job site if the tank is larger than 20’x20’

Step #4: For thick steel walls, heat treatment and stress relieving ensure integrity.

Step #5: Finally, the tank is blasted, primed, and coated to produce the final product.
