The right tank material for every chemical — acids, chlorine, sodium hypochlorite, caustic soda, solvents, fertilisers, and more. GRP, HDPE, FRP, and polypropylene chemical storage tanks from 100 litres to 50,000 litres, available across Dubai, Abu Dhabi, Sharjah and all Emirates.
Using the wrong tank material for a chemical is how spills happen. We match material to chemical before anything ships — here's what each option covers.
High-density polyethylene (HDPE) is the most widely used material for chemical storage tanks in the UAE. It handles most acids, alkalis, and chlorinated compounds up to moderate concentrations, and it's lighter and cheaper than fibreglass or steel for the same capacity.
The weak points: concentrated oxidising acids (strong HNO₃, high-concentration H₂SO₄), aromatic solvents, and halogenated solvents. For those, you need GRP with a vinyl ester liner or a cross-linked polyethylene (XLPE) tank. We confirm chemical compatibility before any order.
| Chemical | Concentration | HDPE Rating |
|---|---|---|
| Sodium hypochlorite (NaOCl) | Up to 15% | ✔ Suitable |
| Hydrochloric acid (HCl) | Up to 37% | ✔ Suitable |
| Sulfuric acid (H₂SO₄) | Up to 70% | ⚠ Check conc. |
| Sodium hydroxide (NaOH) | All conc. | ✔ Suitable |
| Chlorine solution | Dilute | ✔ Suitable |
| Acetone / solvents | Any | ✘ Not suitable |
Glass reinforced plastic (GRP) — also called FRP — is the choice for larger bulk chemical storage tanks, aggressive solvents, and concentrated acids that HDPE can't handle. The key is the liner: a vinyl ester resin liner resists a wide range of acids and solvents; an isophthalic liner works for milder chemicals.
GRP tanks are structurally stronger than polyethylene for the same wall thickness, which matters for large vertical tanks and anything above 10,000 litres. They're also the standard for chemical process tanks and industrial bulk storage across UAE.
| Chemical | Concentration | GRP/FRP Rating |
|---|---|---|
| Sulfuric acid (H₂SO₄) | Up to 93% | ⚠ Vinyl ester liner |
| Hydrochloric acid | All conc. | ✔ Suitable |
| Solvents (acetone, MEK) | Varies | ⚠ Specify solvent |
| Sodium hypochlorite | All conc. | ✔ Suitable |
| Sodium hydroxide | All conc. | ✔ Suitable |
| Hydrofluoric acid (HF) | Any | ✘ Not suitable |
Polypropylene (PP) is harder and more heat-resistant than HDPE, and better suited to certain aromatic chemicals and strong oxidising acids at moderate temperatures. It's widely used for chemical mixing tanks, acid dip tanks, and chemical process vessels where HDPE might soften or swell.
Polypropylene tanks are common in electroplating, surface treatment, chemical stripping, and pool chemical applications. Both natural (translucent) and opaque grades are available. Can be supplied with agitators, heating elements, and bespoke fittings.
| Chemical | Concentration | PP Rating |
|---|---|---|
| Sulfuric acid | Up to 70% | ✔ Suitable |
| Hydrochloric acid | All conc. | ✔ Suitable |
| Nitric acid | Up to 40% | ⚠ Check temp |
| Caustic soda (NaOH) | All conc. | ✔ Suitable |
| Chlorine / bleach | All conc. | ✔ Suitable |
| Aromatic solvents | Any | ✘ Not suitable |
Stainless steel 316 (SS316) is specified where temperature matters, where the chemical demands it, or where food-grade or pharmaceutical standards apply. It handles organic acids, alcohols, some solvents, and high-temperature process chemicals that neither HDPE nor GRP are rated for.
The weak points: chloride-containing solutions at high temperature (risk of pitting corrosion), and hydrochloric acid at any concentration. For those, you're looking at Hastelloy or lined GRP. For everything else, SS316 is the cleanest option — easy to inspect, easy to clean, and accepted by every UAE authority for food-grade and pharmaceutical applications.
| Chemical | Concentration | SS316 Rating |
|---|---|---|
| Organic acids (acetic, citric) | All conc. | ✔ Suitable |
| Alcohols (ethanol, IPA) | All conc. | ✔ Suitable |
| Sodium hydroxide (NaOH) | Up to 50% | ✔ Suitable |
| Hydrochloric acid (HCl) | Any | ✘ Not suitable |
| Chlorine / hypochlorite | Dilute | ⚠ Low temp only |
| Sulfuric acid (H₂SO₄) | Cold, dilute | ⚠ Limited |
From a 100-litre dosing tank for a water treatment plant to a 50,000-litre bulk acid storage tank for an industrial facility — here's what we cover.
This is a guide, not a final specification. Concentration, temperature, and trace contaminants all affect compatibility. We verify material selection for every order before anything ships.
| Chemical | HDPE | GRP/FRP | Polypropylene | SS 316 | Notes |
|---|---|---|---|---|---|
| Sodium hypochlorite (NaOCl / bleach) | ✔ | ✔ | ✔ | ⚠ | UV-stabilised tank recommended; SS pits at high conc. |
| Hydrochloric acid (HCl) — all conc. | ✔ | ✔ | ✔ | ✘ | Never store HCl in SS; HDPE or PP standard choice |
| Sulfuric acid (H₂SO₄) — dilute (<70%) | ✔ | ⚠ | ✔ | ⚠ | GRP needs vinyl ester liner; SS limited below 10% |
| Sulfuric acid (H₂SO₄) — concentrated (>70%) | ✘ | ⚠ | ✘ | ✘ | GRP vinyl ester liner only; or XLPE — call us |
| Sodium hydroxide / caustic soda (NaOH) | ✔ | ✔ | ✔ | ✔ | Most materials suitable; avoid aluminium fittings |
| Chlorine solution / chlorinated water | ✔ | ✔ | ✔ | ⚠ | SS risk of pitting at elevated chloride levels |
| Acetone / ketone solvents | ✘ | ⚠ | ✘ | ✔ | SS316 is the standard choice for ketone solvents |
| Ammonia (anhydrous / solution) | ✔ | ✔ | ✔ | ⚠ | Anhydrous ammonia requires pressure-rated vessel |
