When it comes to manufacturing industrial tanks; whether they are frac tanks, mixing tanks, storage tanks or pressure vessels, the design phase is one of the most critical stages of the entire process.
A well designed tank ensures safety, efficiency, regulatory compliance and long term reliability. Unfortunately poor design decisions can lead to costly failures, operational inefficiencies or even serious safety risks.
At Brisbane Tank Manufacturing, the design phase is treated as the foundation of every successful project. Our experienced engineers, designers and fabrication specialists work closely with clients and each other to ensure each tank is purpose built for its application and built to perform for decades.
Below we outline what typically happens during the tank design phase and why working with an experienced team makes all the difference.
Understanding the Application
The first step in designing any tank is gaining a complete understanding of how it will be used. Tanks across different industries serve very different functions and each application brings unique design requirements.
Key questions addressed during this stage include:
What product will the tank store or process?
What is the required capacity?
Will the tank operate under pressure or atmospheric conditions?
What temperatures will it experience?
Will the contents be corrosive, abrasive or reactive?
Will the tank be mobile, stationary, vertical or horizontal?
For example, a frac tank used in mining or energy operations has very different structural and mobility requirements compared with a stainless steel mixing tank used in food processing. Getting this stage right ensures the tank design aligns perfectly with the operational environment.
Material Selection
Choosing the right materials is essential for durability, performance and safety. Factors such as corrosion resistance, chemical compatibility, structural strength and temperature tolerance all influence material selection.
Common materials may include:
Carbon steel
Stainless steel (various grades)
Duplex stainless steel
Specialty alloys for high corrosion environments
An experienced design team will also consider lifecycle costs, maintenance requirements and industry standards when recommending materials.
Engineering Calculations and Structural Design
Once the application and materials are confirmed, detailed engineering calculations are performed to ensure the tank can safely withstand operating conditions.
This includes:
Wall thickness calculations
Load and stress analysis
Pressure and vacuum design
Structural reinforcement
Seismic and wind load considerations
Transportation and lifting requirements
For pressure vessels in particular, precise engineering is essential to meet strict safety codes and ensure the vessel performs reliably under pressure.
Compliance with Industry Standards
Industrial tanks and pressure vessels must comply with various national and international standards depending on their use and location.
These may include:
ASME standards
Australian Standards (AS)
API specifications
Industry specific compliance requirements
During the design phase, engineers ensure the tank meets all relevant codes and regulatory requirements. This not only protects operators and facilities but also ensures the tank can pass inspections and certifications without delays.
Integration of Components and Features
Tanks are rarely just simple containers. Most require integrated components that support their intended operation.
The design phase will often include planning for:
Nozzles and connections
Manways and access points
Internal baffles or mixing systems
Heating or cooling jackets
Instrumentation ports
Ladders, platforms, and safety systems
Drainage and cleaning systems
Every feature must be carefully positioned and engineered to ensure functionality, safety and ease of maintenance.
3D Modelling and Design Review
Modern tank design relies heavily on advanced CAD modelling. 3D models allow engineers and clients to visualise the final tank before fabrication begins.
This stage helps identify potential issues early such as:
Interference between components
Installation challenges
Maintenance accessibility
Structural optimisation opportunities
Design reviews ensure every detail is checked, verified and approved before manufacturing begins.
Why Experience Matters
The design of industrial tanks is not simply about creating a structure that holds liquid or materials. It requires a deep understanding of engineering principles, industry regulations, fabrication techniques and real world operating environments.
An experienced team can:
Anticipate potential design challenges
Ensure compliance with complex standards
Optimise designs for manufacturability
Reduce costly revisions during fabrication
Improve long term reliability and safety
This expertise ultimately saves clients time, money and operational risk.
