Chemical Storage Tanks
Overview
Plastic materials are widely used in chemical storage applications because they provide excellent chemical resistance, corrosion resistance, and long-term durability. Unlike metal tanks, plastic tanks are not susceptible to rust or chemical corrosion when exposed to many aggressive substances.
Chemical storage tanks are commonly used in:
Chemical processing facilities
Water treatment plants
Industrial manufacturing operations
Agricultural chemical storage
Cleaning chemical storage systems
Laboratory and research environments
Because storage capacity, chemical compatibility, and installation environments vary widely, chemical storage tanks are often custom manufactured to match specific process requirements and installation layouts.
Custom Manufactured to Your Drawings
Chemical storage tanks are typically designed according to project-specific capacity requirements, installation constraints, and process integration needs.
We manufacture tank components based on:
CAD drawings and technical design specifications
Customer sketches or dimensional layouts
Reference designs or existing tank systems
Prototype tanks for process development
Repeat production runs for industrial facilities
All components are fabricated in-house using plastic machining, forming, and welding processes. Mounting features, pipe connections, and access openings are produced according to the supplied specifications.
Because chemical storage systems often integrate with pipework, pumps, and process equipment, most tanks are drawing-led custom fabrications rather than standard products.
Typical Applications
Chemical storage tanks are used in many industrial and commercial processes, including:
Bulk chemical storage systems
Water treatment chemical dosing tanks
Acid and alkali storage tanks
Process chemical holding tanks
Agricultural fertiliser storage tanks
Cleaning chemical storage tanks
Laboratory chemical storage systems
Industrial fluid containment tanks
These systems must provide safe containment, chemical compatibility, and structural stability throughout their operational lifespan.
Recommended Materials for Chemical Storage Tanks
PVC chemical tanks offer excellent resistance to acids, alkalis, and corrosive chemicals, making them a reliable and cost-effective choice for chemical storage and processing applications.
Polypropylene chemical tanks provide excellent resistance to a wide range of corrosive chemicals and elevated temperatures, making them ideal for industrial storage and processing applications.
HDPE chemical tanks offer excellent resistance to a wide range of chemicals and provide strong impact durability, making them well suited for industrial storage and containment applications.

Key Performance Requirements
Mechanical
Chemical storage tanks must withstand the structural loads created by stored liquids.
Typical mechanical considerations include:
Structural strength to support fluid weight
Tank wall thickness appropriate for stored volume
Secure mounting of fittings and pipe connections
Dimensional stability over time
Resistance to cracking or deformation
Environmental
Chemical tanks may operate in demanding environments.
Environmental considerations include:
Resistance to chemical corrosion
Compatibility with cleaning or treatment chemicals
Temperature resistance for stored fluids
UV stability for outdoor installations
Recommended Materials
PVC is widely used for chemical tanks where strong resistance to corrosive chemicals and structural rigidity are required.
Advantages:
Excellent resistance to many acids, alkalis, and corrosive chemicals
Rigid material suitable for structural tank fabrication
Good long-term durability in chemical environments
Limitations:
Lower temperature resistance compared with polypropylene
Can be more brittle than HDPE in high-impact applications
HDPE (High-Density Polyethylene)
One of the most commonly used materials for chemical storage tanks due to its excellent chemical resistance and durability.
Advantages:
Resistant to many acids, alkalis, and industrial chemicals
Good impact resistance
Suitable for large tank structures
Limitations:
Limited resistance to certain strong solvents or oxidising chemicals
Often used where higher temperature resistance is required.
Advantages:
Good chemical resistance
Higher temperature tolerance than HDPE
Suitable for many industrial process tanks
Limitations:
Lower impact resistance compared with HDPE
Material Selection Summary
For many industrial chemical storage applications, HDPE is widely used due to its strong chemical resistance and durability.
Polypropylene may be selected when higher operating temperatures or specific chemical compatibility requirements are involved.
PVC may be used for smaller tanks or fluid handling components, particularly in less demanding environments.
PVDF is typically used in highly aggressive chemical environments where advanced chemical resistance is required.
Material selection should be based on chemical compatibility, operating temperature, and structural requirements.
Design & Installation Considerations
When designing chemical storage tanks, several factors must be considered:
Tank capacity and fluid weight
Chemical compatibility with tank material
Pipe connections and fluid transfer systems
Venting and pressure control requirements
Structural support and installation space
Access for inspection and maintenance
These considerations ensure the tank operates safely within its intended environment.
Alternative Options:
All components used in this application are manufactured in-house using controlled, drawing-led production processes. We do not supply generic or off-the-shelf products. Each part is produced to specification to meet defined mechanical, environmental, and installation requirements.
