You want a supplier who can build your tank while offering three major benefits that many other companies simply can&#;t do.

Let&#;s take a look at three important factors you should demand when ordering a custom tank for your storage requirements.

1. The Storage Tank Must Come With A P. Eng. stamp

The Storage Tank Systems for Petroleum Products and Allied Petroleum Products Regulations specify a number of requirements for a new storage tank.

One is:

&#;For the installation of any storage tank system, the owner of the system must use design plans, drawings and specifications of the system that bear the stamp and signature of a professional engineer.&#; Source: Government of Canada.

The regulations were put in place in to reduce the risk of leaks and spills of petroleum products and to adhere to specific standards that previously weren&#;t enforced.

The P. Eng. stamp shows you the buyer that the drawings, designs, plans, descriptions and/or specifications of the tank meet specific standards that one would expect.

It gives the buyer confidence that the tank has been built satisfactorily to meet these standards.

2. The Storage Tank Works With a VRU

The ideal storage tank is able to work properly in conjunction with a vent gas management system such as a VRU (Vapour Recovery Unit) for both low and high pressure ranges.

A VRU enables the user to better comply with required emissions level regulations and with tighter rules against Volatile Organic Compounds (VOCs) in place.

VRUs have a wide range of applications including petroleum distribution terminals, chemical and petrochemical plants, and crude-oil tanks.

3. The Storage Tank Meets API Standard 650 Guidelines

The American Petroleum Institute (API) represents the oil and gas industry in the US and has created a number of guidelines for the industry to follow and adhere to.

The API Standard 650 is the standard for welded flat-bottomed vertical storage tanks typically used to store liquids such as crude oil as well as gasoline, chemicals or water.

The API remains the only national trade association that represents all sectors of the American oil and natural gas industry. This includes the largest oil companies like Chevron, Exxon and Shell to small independents. 

The API also represents suppliers to the industry such as Siemens, Sulzer, and other companies who build and sell vessels, valves, instrumentation and more.

The Importance of API Tank Standards

OilPro specializes in API guideline designed storage tanks. We have standard-sized tanks as well as a variety of custom tank designs. We have experience providing tanks conforming to API 12F, API 650 as well as API 12B guidelines.

API standards differ depending on the size of the tank, the location of the tank, and what liquid the tank is storing. Thus it&#;s important to choose a builder who understands each standard and ensures that each custom storage tank is designed, manufactured, installed correctly.

Tank shells are also stocked in common sizes and adaptable to your specific requirements ranging from insulation to coating to custom nozzle configurations and internals.

Custom tank manufacturing for welded or bolted tanks abroad can be ordered using our experienced tank erectors.

Your Essential Guide to Fabricated Storage Tanks

The term &#;storage tank&#; has a remarkably broad definition. While it sounds simple enough, a storage tank will vary from person to person and industry to industry.  Custom fabricated storage tanks can be designed and built to contain organic liquids, non-organic liquids, vapors, or solids. These custom tanks are specifically designed and built with a customer&#;s need and usage in mind. Industries where storage tanks can be found are typically industries consuming or producing good, liquids, and or vapors. Industries like petroleum either in producing or manufacturing petroleum, chemical engineering and or manufacturing, and the agriculture industry for bulk storage.

Types of Tanks

The use of the storage tank and what it will contain will determine the type of tank required.

Spherical storage tanks &#; Spherical storage tanks are mainly used for storage of high-pressure fluids. The curved shape makes spherical tanks very strong. The even distribution of stresses on the sphere&#;s surfaces, both internally and externally, generally means that there are no weak points. Spheres however, are much more costly to manufacture than cylindrical vessels.  An advantage of spherical storage vessels is, that they have a smaller surface area per unit volume than any other shape of vessel.

This means, that the quantity of heat transferred from warmer surroundings to the liquid in the sphere.

Cylindrical Storage Tanks &#; Cylinders are widely used for storage due to their being less expensive to produce than spheres. However, cylinders are not as strong as spheres due to the weak point at each end.  Hemispherical or rounded ends being fitted reduce this weakness. If the whole cylinder is manufactured from thicker material than a comparable spherical vessel of similar capacity, storage pressure can be similar to that of a sphere. 

Fixed Roof Storage Tanks &#; Fixed-roof tanks are usually the least expensive to construct. They are generally considered the minimum acceptable equipment for storing liquids. A typical fixed-roof tank consists of a cylindrical steel shell with a cone- or dome-shaped roof that is permanently affixed to the tank shell. Storage tanks are usually fully welded and designed for both liquid and vapor. A breather valve is often installed on fixed-roof tanks. This allows the tank to operate at a slight internal pressure or vacuum. This valve prevents the release of vapors during only very small changes in temperature, barometric pressure, or liquid level.

Floating Roof Tanks &#; Storage tanks with floating roof are mainly used for stores near atmospheric pressure. Floating roofs are designed to move vertically within the frame of the tank to provide a constant minimum gap between product surface and the ceiling and provide a continuous seal between the periphery of the tank and the floating roof. These can be made of a type that is exposed to the environment or a type that is within a fixed roof. The internal floating roof tanks with an external fixed roof are used in areas of heavy snowfall since the accumulation of snow or water affects the operation of buoyancy.

Both tanks, fixed roof or internal floating are used to reduce steam losses and preserve the stored fluid. A typical external floating roof tank consists of an open-topped cylindrical steel shell equipped with a roof that floats on the surface of the stored liquid, rising and falling with the liquid level. External floating roof tanks are equipped with a rim seal system, which is attached to the roof perimeter and contacts the tank wall. The rim seal system slides against the tank wall as the roof is raised and lowered.

Materials of Construction

Storage tanks can be fabricated from several different materials. They type you choose for your tank will depend on how you will use the tank, the material you plan to store and the conditions in which you will store it.

Stainless Steel &#; Stainless steel is a common option for storage tanks, and with good reason. Welded stainless steel tanks are incredibly durable, as well. Stainless steel offers resistance to corrosion, rust, fire and UV light, which means that these tanks last considerably longer than welded steel or concrete. A welded stainless steel tank is also a leak-free storage solution, meaning you can trust that what you store inside will stay inside. Various linings can be added to the inside of a stainless steel tank to allows for a variety a uses from storing water and food materials to chemical fertilizers and petroleum products.

Stainless steel also has a long lifespan that makes it quite affordable. The cost of ownership is lower than a concrete or bolted steel tanks. Stainless steel tanks require les maintenance and will last much longer. Additionally, Stainless steel tanks are an eco-friendly storage option. Stainless steel is completely recyclable once a tank is taken out of service, and more than half of new stainless steel being used today is made from previously recycled material.

Carbon Steel &#; Carbon steel has higher carbon content than stainless steel. Because of the larger amounts of carbon, tanks created with this material offer better heat distribution. This is useful for customers who plan on heating the contents of their tank. Carbon steel is also wear resistant, which is an important quality in an industrial tank, as well as malleable.  The higher carbon content makes the steel harder and stronger than other steels.  Tanks made with carbon steel tend to be more affordable.  A tank made with carbon steel will require less materials than a stainless steel tank, while the materials are less expensive than those used for exotic metal tanks. Carbon steel is usually preferred in situations where the tank will be stored indoors or under cover. Since carbon steel is more prone to rusting, it is best to place these tanks indoors.
