Constructing Precision-Engineered Storage Tanks: A Technical Overview

The fabrication of storage tanks is a process approached with meticulous attention to detail by our engineering teams. This article aims to provide a comprehensive overview of the procedural steps undertaken to ensure the structural integrity and operational success of storage tanks designed for a variety of applications.

Given the diverse requirements of storage tank construction, based on tank dimensions and intended use, the methodology may be adapted; however, the core stages of installation are universally applicable.

Initial Site Preparation

Selecting an optimal location forms the foundational step in tank construction. Critical considerations include:

  • Soil stability analysis
  • Strategic accessibility evaluation
  • Proximity analysis regarding utilities

Subsequent to the determination of an appropriate site, the preparation phase involves vegetation clearance, ground leveling, and conditioning to facilitate the onset of construction activities.

Foundation Engineering

Comparable to the principle that a robust house requires a solid foundation, the construction of a storage tank begins with establishing a strong base. The foundation options predominantly include a reinforced concrete pad or a compacted gravel base, tailored to the specific load requirements and structural specifications of the tank.

Shell Assembly

The assembly phase marks the commencement of the tank’s physical construction. Utilizing high-grade steel plates, the tank’s shell is constructed in a sequential layering process, with each ring securely fastened to its predecessor. The adoption of bolted connections over welding techniques significantly enhances assembly efficiency, reducing installation time compared to conventional methods.

Roof Installation

Following the shell assembly, the construction of the roof involves the installation of structural supports, beams, and decking, culminating in the placement of the roof. Specialized roofing structures, such as geodesic domes, are integrated at this juncture as per design requirements.

Integration of Safety and Accessibility Features

To facilitate maintenance and operational integrity, the addition of ladders, platforms, guardrails, and anti-slip surfaces is essential. These features are designed to ensure safe and convenient access for maintenance personnel and staff.

Fitting and Connection Configuration

The operational functionality of storage tanks often necessitates the integration with external systems. Accordingly, our team installs essential fittings including valves, vents, and connections to accommodate supply lines, pumps, and ancillary equipment, ensuring compatibility with the tank’s intended application.

Comprehensive Testing and Certification

Ensuring compliance with industry standards (e.g., AWWA, Eurocode) is paramount. Our team conducts thorough leak detection, and visual inspections to certify the tank’s integrity and operational readiness, adhering to rigorous quality assurance protocols.

Project Finalization

Upon successful completion of testing and inspection phases, a final review is conducted to ensure all components are securely integrated and fully operational, marking the readiness of the tank for service.

4 Benefits of Vertical Standing Seam Panel Insulation Systems

The right insulation system can help you increase the lifespan of your large storage tanks, protecting them from the expansions and contractions that come from temperature changes.

The right insulation can also protect the contents of your tank, especially during the winter, when they might be prone to freezing. In some high-heat environments, the right insulation can also protect the contents of your tank from degrading when temperatures rise above optimum levels.

If it has become necessary to add insulation to your tanks, or if you wish to add insulation to your tanks prior to use, then our vertical standing seam panel insulation systems are often the right choice. Here are four reasons why this is so. 

#1) They’re Easy to Install

Vertical standing seam panel insulation systems can be installed without scaffolding. They don’t require any welding because they use an internal cable and clip system to secure them to the tank wall.

This means they go up quickly, safely, and cost-effectively when compared to horizontal panels, which must be stacked in rings around the tank.

Our standing seam panel insulation systems are engineered to work with all types of tanks, making them a versatile choice regardless of your application.

#2) They’re Easy to Transport

Vertical standing seam panels may be stacked and packed in crates, then transported straight to your job site. They’re smaller, as they are each two feet wide versus 50-foot horizontal panels.

Transportation thus costs far less than it would for other options, as these panels require no special permits and take up less space. 

#3) They’re Extremely Reliable

Vertical panels are less likely to shift over time. They tolerate extreme weather conditions very well. They’ve been designed to maintain a watertight connection regardless of fluctuating temperature conditions. 

#4) Low Ownership Costs

Vertical panels don’t require ongoing maintenance and are moisture-resistant. If a single panel fails, that panel may be replaced without forcing you to install a brand-new insulation system. 

The low-maintenance nature of vertical standing seam insulation panels reduces the costs of owning the panels and the costs of owning your storage tanks as well.

By contrast, horizontal panels require monitoring and tightening of the bands, which secure the panels to the tank in order to prevent buckling.

What is Cathodic Protection in Tanks?

Cathodic protection is a method of controlling corrosion inside storage tanks. You can combine cathodic protection with tank coating to double the lifespan of the coating.

Here is what you should know about these systems before purchasing them as an option for your tank.

 

Is cathodic protection cost-effective? 

Cathodic protection is extremely cost-effective, both because the cost of installation is relatively low and because it can extend the life of the tank coating by as much as 20 years. 

 

How does cathodic protection work? 

Cathodic protection relies on the use of a “sacrificial anode.” A sacrificial anode is a metal that is more reactive than the tank material. 

The anode corrodes instead of the tank metal.

The protection is primarily added to the interior of the tank, which is where the highest risk of corrosion exists.

 

What types of cathodic protection exist?

There are two types.

The first type is galvanic cathodic protection. Galvanic systems use anodes connected in a circuit. Galvanic protection uses the natural difference between the anode and the structure to drive natural currents to the anode. These systems are the most cost-effective and are the ones that the vast majority of our clients choose to use.

The second type is impressed current cathodic protection, which requires an external power source to drive current to the anode. These systems last longer, are easy to monitor, and offer greater system control.

 

Is it possible to retrofit a tank with cathodic protection?

Yes, it is possible. In fact, FORGE does offer an ancillary equipment installation service that would allow us to retrofit your tank for you. 

 

How do you choose the right cathodic protection systems for tanks?

The right protection depends on tank material and tank size, as well as your budget and needs. 

 

How can I make sure my tank has cathodic protection?

Talk to our engineers when you order your FORGE tanks. Our potable water tank systems are engineered and fabricated to satisfy the specifications you give us, including cathodic protection standards.

We are there for you from the design phase to the construction phase and thus can create a comprehensive cathodic protection solution for you.
