The Best Choice for Chemical Storage


Why Use Thermoplastic Spiral Wound Chemical Storage Tanks?

Deciding which tank technology to use when storing chemicals means considering many factors.

As well as the all-important cost and project ROI, there’s also the chemicals being stored, health and safety requirements, and an increasing pressure to make the most environmentally friendly chemical storage decision possible.

Purchase decisions need to not just meet legal requirements or organisational environmental policies, but also our own individual responsibility to make the best choices for our planet!

Environmentally responsible chemical storage is possible. Since 1964, Chem Resist have pioneered using Thermoplastics as the best materials for transferring and storing chemicals. These materials offer resistance to a broad range of aggressive and corrosive chemicals including Sulphuric Acid, Hydrochloric Acid, Sodium Hypochlorite and Ferric Sulphate. And importantly, they can be recycled at the end of life.

What is Spiral Wound Manufacturing?

Spiral Wound Manufacturing is used for a variety of components. Spiral Wound gaskets are common, for example. Spiral Wound Storage Tanks have been a specialty of Chem Resist since the 1990s.

Spiral Wound Manufacturing gives us complete flexibility and total control over the exact diameter, height and capacity of the tanks we make.

Each tank is manufactured by precisely winding a strip of extruded thermoplastic at high temperature. This means the edges of the strip overlap and fuse to form a homogenous solid tank wall with no weak seam welds.

Once the tank cylinder is finished, a lid and base are added. We can also add ancillaries such as access manways, handrails, ladders, level instrumentation and ducts to the tank – all to your exact specification.

Designed, Manufactured and Tested for your peace of mind

At Chem Resist, we work to recognised standards throughout the design, manufacture and testing process.

Every Chem Resist chemical storage tank is designed and manufactured to BS EN 12573:2000.

All lids, bases and nozzles are welded internally and externally by our Fabricators, who are all trained and certified in accordance with BS EN 13067:2003

As a final quality check for our customers, each tank is hydrostatically tested to DVS-2206-2.

And each one is Built with Integrity.

Spiral Wound Thermoplastics – the environmental choice for Chemical Storage

Organisational decisions need to align with environmental policies and best practice.

Financial investments, energy providers and company cars are regularly decided based on the best solution for the planet and future generations – now the same can be true for Chemical Storage Tanks.

Spiral Wound Thermoplastic Storage Tanks generate a lower carbon footprint when compared to other available tank technologies including Steel and GRP (Glass Reinforced Plastic).

If you compare the combined energy needed to produce the raw material and manufacture a 40m3 Hydrochloric Acid tank, Spiral Wound Thermoplastic Tanks produce the lowest carbon footprint.

And at the end of life, the Thermoplastics we use can be fully recycled and ground back into pellets that go on to make low-pressure industrial pipe.

How is Spiral Wound Manufacturing different?

When compared to the alternatives, whether it’s GRP or Steel, Spiral Wound Thermoplastics offer a number of advantages.

A low carbon footprint that’s 50% of carbon steel, 35% of hot cured GRP, and 15% of stainless steel.

The lowest carbon footprint you’ll find for chemical storage tank manufacturing.

No weak seam welds in the tank wall.

Spiral Wound tanks have a homogenous wall which minimizes any potential loss of containment incidents.

Thermoplastics offer great resistance to a broad range of corrosive and aggressive chemicals.

Including Sulphuric Acid, Hydrochloric Acid, Sodium Hypochlorite and Ferric Sulphate.

Bespoke tanks in any diameter from 0.8m to 4.3m, with volumes up to 130m3.

Thanks to the flexible nature of the manufacturing process.

20-year design life as standard.

Spiral Wound Thermoplastic tanks are not constrained by a limited number of fill and empty cycles.

Fully recyclable solution.

Unlike GRP, Spiral Wound Thermoplastic tanks can be recycled at end of life, and ground back to be reused as low-pressure industrial pipe.
