T BAILEY LLC fabricates custom bulk storage tanks for fuel, chemical, water, gas, and liquid applications from our facility in Anacortes, Washington. We build shop-built and field-erected tanks in carbon steel and stainless steel. Our own crews prepare the plate, fabricate and weld the tank, then blast, coat, test, and deliver it. You work with one accountable team from the first cut of plate through final installation, backed by heavy steel fabrication experience. When your project requires a bulk storage tank matched to a specific product and code, we engineer it to the standard that governs the service.

What a Bulk Storage Tank Is
A bulk storage tank is a large-volume steel vessel built for the aboveground storage of liquids and gases at an industrial scale. We fabricate bulk storage tanks for liquids and gases in single-wall or double-wall configurations, in vertical or horizontal orientation, and sized to the site.
What the tank holds drives the specification. The stored product sets the material, the lining, the containment requirement, and the governing code. A vertical bulk storage tank maximizes capacity within a limited footprint, and our vertical storage tank page covers that orientation in full.
Bulk Storage Tanks by Stored Product
We fabricate bulk storage tanks for a wide range of products, each with its own material, coating, and code requirements.
Bulk Fuel Storage Tanks
Bulk fuel storage tanks hold diesel, gasoline, jet fuel, and other petroleum products for depots, fleet fueling, and standby power systems. These bulk fuel tanks are commonly double-wall units with interstitial leak monitoring and secondary containment sized to 110% of tank capacity under EPA SPCC. We fabricate them to UL 142 and STI F921, and to the UL 2085 protected standard, which rates a bulk fuel storage tank for fire, ballistic, and impact resistance where a release would carry serious consequences.
Bulk Chemical Storage Tanks
Bulk chemical storage tanks hold process chemicals, acids, and industrial fluids across manufacturing and water treatment. Material selection drives a bulk chemical storage tank, since the corrosivity of the stored substance decides between carbon steel with a lining and stainless steel. Where corrosion resistance governs, we fabricate the chemical bulk tank in stainless steel and verify the alloy with positive material identification. Chemical storage is heavily regulated, and programs such as New York’s hazardous substance bulk storage regulations set inspection and containment requirements operators plan around.
Bulk Water Storage Tanks
Bulk water storage tanks serve potable water, municipal water, process water, and fire suppression systems. A bulk water storage tank is typically carbon steel with an interior lining selected for the stored water and local health codes. For municipal and industrial water storage, we build to AWWA D100.
Bulk Gas and Low-Pressure Storage Tanks
Bulk gas storage tanks hold products that cannot be stored at atmospheric pressure, including liquefied and cryogenic gases. We fabricate these low-pressure bulk storage tanks to API 620 for pressures up to roughly 15 psig. Where a product is stored above 15 psig, an ASME Section VIII pressure vessel is the correct design, and our ASME pressure vessel line covers that work. Bulk liquid storage tanks for lower-pressure petroleum, chemical, and water service are most often built to API 650, the welded steel tank standard used across refineries and terminals.
We also build condensate tanks, cone-bottom tanks for products that must drain fully, and hopper-bottom fuel tanks, each configured to the product it serves.
Codes and Standards We Build To
Every bulk storage tank is built to the code that governs its product and service. The standards most often specified include the following:
- ASME Section VIII, Division 1: Pressure vessels for products stored above 15 psig.
- API 620: Low-pressure tanks for gases and cryogenic products, from 0.5 to 15 psig.
- API 650: Welded steel tanks for petroleum and general liquid storage up to about 200°F.
- API 653: Inspection, repair, and alteration of in-service tanks.
- UL 142 and STI F921: Aboveground atmospheric tanks for flammable and combustible liquids, with a UL 142 working pressure limit of 0.5 psig.
- UL 2085: Protected tanks rated for fire, ballistic, and impact resistance.
- AWWA D100: Welded steel tanks for municipal and industrial water storage.
We confirm the applicable standard with your engineering team before fabrication, so the finished tank carries the listing your permit and insurer require.
Custom Sizing and Materials
Bulk storage tanks range from modest process vessels to very large field-erected tanks, and we fabricate across that span. Tanks within transport limits are built in our shop, while larger tanks are fabricated in sections in-house and assembled on-site by our crews as field-erected tanks.
We fabricate in carbon steel for most liquid service, and in stainless steel where corrosion resistance or sanitation governs. Our heavy plate rolling capacity and large capacity cranes let us take on wall thicknesses and diameters many regional tank fabricators cannot.
