Spiral wound chemical storage tanks manufactured in HDPE and Polypropylene
Originally developed in partnership with Cambridge University in the early 90’s and continuously improving, our spiral wound manufacturing method creates the highest quality, market-leading chemical storage tanks. Capable of safely storing chemicals ranging from weakly acidic/alkaline, up to those which are highly oxidising such as 96% Sulphuric Acid or 15% Sodium Hypochlorite.
We have the capacity to manufacture vessels up to 4.2m in diameter and 125,000l capacity, following the current market trend for larger capacity tanks for bulk chemical storage. Every chemical storage tank we design meets our customers exact requirements and conforms to the British and European standard BS EN 12573: 2000 ‘Welded static non-pressurized thermoplastic tanks’.
We specialise in using thermoplastics due to their inert nature when dealing with some of the most aggressive chemicals. Specifically, we use Corrosion Resistant Polypropylene and High-Density Polyethylene (PE100-RC).
We are also able to provide full Turnkey Project Services including delivery and site installation and a broad range of Valves, Pumps and Controls and ChemiGuard Pressurised Offloading Cabinets and Pumped Offloading Cabinets and Dosing Cabinets for safe fluid transfer.

Frequently asked questions
-
● Chemical storage tanks are used to provide safe storage of liquid and chemicals. These are typically located outside, multiple tanks together are known as a ‘tank farm’.
● A processing tank can be used to mix or blend chemicals, these can vary in size and can be located outside or within a building depending on the chemicals and volumes involved in the application.
● The key difference is the purpose of the tank. Chem Resist use thermoplastics, HDPE (High Density Polyethylene, PE100-RC) and Polypropylene to manufacture chemical storage tanks, the choice of material depends on the demands of the application. -
A thermoplastic chemical storage tank is a vessel used to store liquid or chemicals, manufactured using thermoplastic. The features included in the tank will depend on the chemical and application. However, every tank will have a fill point where the liquid will enter the tank and a nozzle from which it will be drawn.
-
A chemical storage tank provides safe containment for a specific liquid or chemical. It will be designed and manufactured to meet the demands of the application which will include variables such as the chemical, working temperature and volumes to be stored. Chemical storage tanks can also be designed to include bunds, access manways to the top or side, vents, nozzles and methods of level indication.
-
No, thermoplastics do not rust. All of our thermoplastic chemical storage tanks are resistant to corrosion on the inside and outside.
-
● Unlike GRP and fibreglass, thermoplastics are recyclable. GRP typically ends its life in landfill.
● The production of fibreglass uses and produces hazardous materials.
● Thermoplastic is lighter than fibreglass. -
● Chem Resist combine thermoplastics with our spiral wound manufacturing method resulting in the lowest carbon footprint. If we compare a 40m3 tank for Hydrochloric Acid, the carbon footprint created from cradle to gate is significantly less for Spiral Wound Thermoplastics when compared to GRP or stainless steel.
● Thermoplastic tanks are lighter than the steel alternatives, resulting in lower transport and fuel costs.
● Our tanks can be removed at the end of their life and then dismantled, with the plastic being ground back into pellets which then manufacture a range of components such as low-pressure industrial pipe – watch how it’s done.To find out more, download the white paper below.

“THE CHEMICAL STORAGE CARBON FOOTPRINT”
If you’re interested in learning more about Chemical Storage tanks manufactured using the Spiral Wound method – how they can be used to benefit your organisation and the environment when compared to the alternatives – download our white paper to learn more about the carbon footprint of chemical storage.
Prepared by Chem Resist Sales Director Gary Smith and Technical Manager Stephen Menzer, the white paper breaks down both the business and environmental case for spiral wound manufacturing.
Calculating the height of your tank
The height of your tank is determined by more factors than just the volume of liquid you need to store – safety margins, overflows, pipework, vents and handrails all play a role in the final size. Click below to watch the video on how our team calculates the height of your tank.
