Carbon steel shell, chemical-resistant epoxy inside.
The default tank for ETP chemical dosing and corrosive process water, where stainless is more cost than the duty needs and carbon steel alone will not survive the medium. Fabricated in Kenya, lined to the chemistry, cured before delivery.
The tank that exists where stainless is overkill and carbon alone is wrong.
A lot of process duty sits in the gap between food-grade hygiene and bulk water storage. Acid dosing, polymer preparation, treated effluent intermediate storage, caustic CIP loops. Stainless overspends on the duty; carbon steel pits or corrodes through inside two years.
Epoxy-lined tanks fill that gap. The shell is carbon steel S275 or S355 to handle the structural load. The interior is blast-cleaned to Sa 2.5 and coated with a two-component chemical-resistant epoxy, picked against the specific medium and concentration on the brief.
We supply with either an industrial-grade or food-grade lining where the duty allows it. The lining cure schedule runs inside the shop, so the tank arrives on-site ready to fill.
Lining is picked to the medium.
The numbers below are the default. The right epoxy for your chemistry is a conversation, not a catalogue. Tell us the medium and concentration; we will quote the lining system that matches.

- Capacity range
- 1 to 200m³
- Wall thickness

- Lead time, Kenya
- 5 to 8 weeks ex-works, including lining cure time
Where epoxy-lined steel does the job.
ETP chemical dosing
Alum, ferric chloride, lime, polymer dosing tanks for effluent treatment plants where stainless is overkill and carbon steel won't survive the medium.
Acid storage
Dilute sulphuric, hydrochloric, and phosphoric acid storage. Lining grade picked against the specific acid and concentration.
Caustic and alkali
Sodium hydroxide dosing, CIP caustic loops, treated alkaline effluent storage.
Treated water polishing
Intermediate storage between treatment stages where neutral or near-neutral pH is the operating point.
