When is an acid-proof tank in 316 or 316L required?
Acid-resistant 316/316L stainless steel tanks are often used in processes where liquids can be more corrosive, such as in the chemical, food and pharmaceutical industries.
The properties of the material can contribute to increased resistance to, for example, acids and chlorides, depending on the application, concentration and operating conditions.
Processöverskott offers both new and used acid-resistant tanks in various sizes and designs. This provides the opportunity to find solutions for different types of processes and applications.
Function and structure
Acid-proof tanks in 316/316L are widely used for storage, mixing and handling of liquids that can be corrosive in the process industry.
The design is usually cylindrical and can be designed for both vertical and horizontal placement, depending on the application. The bottom can in some cases be conical, which can facilitate emptying and handling.
Tanks may be equipped with, for example, inspection hatches, level measurement and valve connections, depending on the design and previous use. For processes requiring circulation, agitators may be present, and CIP systems may be present in some applications for cleaning without disassembly.
Materials and construction
Acid resistant 316/316L contains molybdenum, which can contribute to increased resistance to chlorides and some acids in various process industry applications.
316L has a lower carbon content, which may reduce the risk of impact in welded joints in certain applications, depending on operating conditions.
Tanks made of these materials are usually welded and may have different surface treatments, such as mirror or satin polishing, depending on process requirements and cleaning needs.
Pressurized and atmospheric solutions
Acid-resistant tanks can be atmospheric for the storage of aggressive liquids or pressurized for processes that require positive or negative pressure, such as mixing chemicals under controlled conditions. Pressurized tanks are equipped with safety valves and pressure monitoring to reduce the risk of anomalies and protect both product and personnel.
Applications in industry
- Chemical industry: storage and mixing of acids, bases and corrosive solutions.
- Pharmaceutical production: handling of sterile and chemically aggressive solutions.
- Food industry: products with acidic ingredients, such as juices, fermented foods or acidified raw materials.
- Water treatment: chemical tanks for acids, chlorine or buffer solutions.
- Special processes: laboratories, pilot plants and small-scale chemical production.
Technical options and equipment
- Internal agitators for homogenization.
- Temperature jacket for heating or cooling.
- Inspection hatches and level gauges for process control.
- CIP system for hygienic cleaning of corrosive products.
- Valves and pump connections adapted for chemicals and aggressive liquids.
