Manufacturing industries are showing a positive growth trajectory, riding on continued growth in economic activities globally. As industrial growth is going upward, the demand for acid storage tanks is also increasing. This is a positive sign for companies engaged in manufacturing industrial tanks in India.
Learning about chemical storage tanks
These tanks are designed in a special way to minimize the ice crystallization process and other harmful effects during storage. These tanks are engineered to hold and store different types of liquids and gases at varying pressure and temperatures. The special tanks are available in various shapes and sizes. As far as mounting is concerned, these tanks are mounted both vertically and horizontally.

As far as costing is concerned, it varies from company to company. We recommend you compare costs before taking a final decision to buy the product.
Types of industrial storage tanks
Manufacturing industries are using a wide range of acid process tanks and industrial storage tanks for a wide range of objectives. Some of the commonly used storage tanks in manufacturing industries are fixed-roof tanks, horizontal tanks, external floating roof tanks, internal floating roof tanks, pressure tanks, doomed external floating roof tanks, LNG tanks, and variable vapor space tanks.
3 commonly used industrial storage tanks
In this important section, we are going to talk about 3 commonly used industrial tanks. These have been classified based on their storage objectives.
- Liquid tanks
- Bullet tanks
- Bunded tanks
Liquid tanks
As indicated by the classification, these specially designed industrial chemical storage tanks are manufactured for safely storing volatile and non-volatile liquids industrial liquids. Given their importance and application in manufacturing industries, these are engineered by using robust raw materials combining the latest machines and tools. These can withstand corrosion and other harsh environmental conditions.
Bullet tanks
These types of acid process tanks are cylindrical in shape and are designed for bulk storage in large tanks. As far as applications are concerned, the bullet tanks are engineered for storing low melting points liquefied gases, for example, butane and ammonia. These tanks can hold bulk quantities of gases under a temperature below – 148 degrees Fahrenheit.
Bunded tanks
This is a special type of industrial storage tank as these tanks possess a secondary containment tank on their outer side. What is the purpose behind the outer tanks? The outer tanks act as a catch system for preventing oil spills. As oil spill leads to harmful effect on the environment, the protective layer adds to the robustness of the tank.
Custom-designed acid process tanks
A few leading acid process tank manufacturers in Ahmedabad hold the expertise to deliver custom-designed chemical storage tanks. For your specific requirement, you can connect with a leading chemical storage tank manufacturing company. Never settle for less. Inferior quality wouldn’t serve any purpose.
Conclusion
Quality makes all the difference. Never compromise with the quality of the acid storage tank.
Plants that handle acids, alkalis or treatment chemicals rely on two kinds of industrial chemical tanks: those that hold chemicals until they are needed, and those where the chemistry happens.
A chemical storage tank contains a chemical at rest. A chemical process tank holds an active bath that products are dipped into, so it must also withstand immersion, heat, agitation and fumes.
Both may use the same plastics, but a tank specified for one job is rarely right for the other. Understanding chemical process tanks vs chemical storage tanks helps you avoid leaks, downtime and compliance gaps.
This guide is by Arvind Corrotech, an Ahmedabad-based manufacturer of galvanizing plants, process tanks and chemical storage tanks.
What Are Chemical Storage Tanks?
Definition and Purpose
Chemical storage tanks hold raw chemicals, intermediates or waste liquids until they are used, transferred or treated. Their job is containment: keeping an aggressive liquid in and weather and contamination out. The liquid is mostly at rest, so the main loads are the weight of the contents and, outdoors, sun and weather.
Common Materials Used
Material choice depends on the chemical, its concentration and temperature, and where the tank stands:
- Polypropylene (PP): Arvind’s polypropylene tanks use homopolymer and copolymer PP, joined by butt-fusion welding.
- High-density polyethylene (HDPE): light, non-corrosive and suited to many acids and alkalis.
- PP+FRP: a thermoplastic lining with an FRP outer skin, which Arvind uses for high temperatures and strong acids.
- FRP: for specific industrial requirements.
For acid storage tanks, Arvind recommends special polypropylene sheet inside a shed, and HDPE or UV-resistant polypropylene outdoors.
Applications and Industries Served
Chemical storage tanks commonly hold hydrochloric acid, sulphuric acid, sodium hydroxide, sodium hypochlorite, ferric chloride and wastewater awaiting treatment. Typical users include steel and galvanizing plants, chemical units, textile, leather, paper and plastics processors, and effluent treatment plants. Like other industrial storage tanks, their shape follows the site. Vertical, horizontal and square storage tanks suit different floor space, and a conical bottom lets sludge-forming chemicals drain completely.
What Are Chemical Process Tanks?
Definition and Purpose
Chemical process tanks, also called chemical processing tanks, hold a working bath in which a product is treated. Steel, wire, pipes or components are lowered in, held for a set time and lifted out.
Key Features and Specifications
Process tanks are engineered for movement, heat and fumes:
- Open-top construction, sized to the largest workpiece and the crane or hoist that loads it.
- Structural reinforcement: Arvind’s pretreatment tanks use a steel-reinforced solid polypropylene shell on support frames of FRP-coated rectangular hollow sections.
- Welding to recognised codes: Arvind states these tanks are designed to DVS 2205 and constructed to BS EN 12573, with butt-fusion welded walls.
- Heating and temperature control, for example in flux tanks.
- Fume capture, such as suction ducts along the sides and ends of Arvind’s pickling tanks.
Applications in Chemical Processing
Process tanksare the core of surface-treatment lines:
- hot dip galvanizing pretreatment;
- wire, pipe and tube pickling;
- electroplating and anodizing;
- powder-coating pretreatment;
- quench and passivation after galvanizing.
Arvind builds quench and passivation tanks, which receive hot work from the zinc kettle, in epoxy-coated mild steel.
Key Differences Between Chemical Process Tanks and Chemical Storage Tanks
| Aspect | Chemical storage tanks | Chemical process tanks |
|---|---|---|
| Main job | Contain chemicals safely over time | Treat products in an active bath |
| Typical shape | Closed vertical, horizontal or square tank with vents | Open-top rectangular tank sized to the workpiece |
| Loads | Mainly the static weight of the contents, plus weather outdoors | Contents plus immersion, crane impacts, agitation and heat |
| Temperature | Usually ambient | Often heated or temperature-controlled |
| Fumes | Vented through a controlled outlet | Extracted at the bath |
The line can blur: Arvind’s closed-top vertical tanks serve both storage and process duty. Classify a tank by what happens inside it.
Design and Construction Considerations
A storage tank is designed around the liquid, its density and its location. A process tank must also survive daily mechanical stress: heavy loads go in and out, and the walls flex as baths heat and cool. It therefore usually needs external reinforcement and carefully specified welds.
Functionality and Operational Differences
Storage tanks are filled, checked and drawn off on a schedule. Process tanks are in continuous use: chemical strength drifts, sludge builds up, temperature must stay in range, and operators work at them every shift.
Maintenance and Safety Considerations
- Storage tanks: inspect for cracks, discolouration and leaks. Keep vents clear and level gauges working, and protect outdoor tanks from UV.
- Process tanks: monitor bath chemistry and remove sludge. Inspect welds and corners where loads strike, and keep fume extraction working.
- Both: spill containment around the tank is good practice.

Choosing the Right Tank for Your Needs
Factors to Consider
- Capacity: size storage around your consumption between deliveries, plus a safety margin. Arvind builds acid storage tanks from 1 KL to 100 KL (company figure). Size process tanks to the largest workpiece and the line’s throughput.
- Materials: match the tank material to each chemical’s concentration and temperature, and confirm compatibility with the manufacturer.
- Regulatory compliance: in India, the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989 require clear labelling of hazardous chemical containers and safety data sheets, plus safety reports and an on-site emergency plan above threshold quantities.
How to Assess Your Specific Requirements
Before requesting quotes, list each chemical with its concentration and temperature, your daily consumption or line throughput, the floor space and whether the tank sits indoors or outdoors, the loading method, fume and effluent arrangements, and the standards the tank must meet.
With those inputs, a chemical tank manufacturer can recommend the right material, shape and reinforcement. For more storage options, see our guide to different types of chemical storage tanks.

Frequently Asked Questions
What is the difference between a chemical storage tank and a chemical process tank?
A chemical storage tank contains chemicals safely until they are used, with the liquid mostly at rest. Chemical process tanks, also called chemical processing tanks, hold an active bath in which products are treated, so they also need reinforcement, heat control and fume extraction.
What materials are used in chemical storage tanks?
The most common materials are polypropylene, HDPE, PP+FRP and FRP. Polypropylene suits tanks inside a shed, while HDPE or UV-resistant polypropylene is preferred outdoors. The right choice depends on the chemical, its concentration and its temperature, so check compatibility against a resistance chart and confirm it with your tank manufacturer.
How do I determine the right size for my chemical tank?
For a storage tank, size it to your consumption between deliveries, add a safety margin, and make sure it can take a full delivery. For a process tank, start from the largest workpiece, the crane or hoist that loads it, and the throughput your line needs.
What safety standards should chemical tanks meet?
It depends on the tank and the liquid. Welded thermoplastic tanks are commonly built to BS EN 12573 and designed to the German DVS 2205 code; Arvind states its pretreatment tanks follow both. Rotationally moulded polyethylene tanks are covered by ASTM D1998. In India, the hazardous chemical rules of 1989 add duties for labelling, safety data sheets and emergency plans.
