Are used stainless steel tanks safe in the process industry?
Used stainless steel tanks can be safe in the process industry if they are properly inspected, cleaned and adapted to the current process. The condition of the tank, previous use, materials and documentation are important factors in assessing safety and suitability.
Processöverskott offers both new and used tanks in Stainless 304 and Syrafast 316 in several different designs for industrial processes in areas such as food, chemistry, pharmaceuticals and water treatment.
Function and structure
Used tanks have basically the same construction as new tanks.
Common components:
– Stainless steel tank body
– Inlet, outlet and process connections
– Possible insulation and jacketing
– Stirrers and internal process equipment
– Manholes, valves and level measurement
The design of the tank varies depending on previous use and application.
Materials and construction
Common materials:
– 304 stainless steel for standard applications
– 316 or 316L acid-proof for more corrosive environments
When assessing used tanks are often checked:
– Coatings and corrosion
– Welds and connections
– Possible deformations or damage
– Hygienic surfaces and cleaning possibilities
The choice of material affects longevity, hygiene and corrosion resistance.
Pressurized and atmospheric solutions
Used tanks can be:
– Atmospheric storage tanks
– Pressurized process tanks
– Vacuum rated tanks
– Double jacketed solutions
For pressurized tanks, documentation and control of design, pressure rating and safety equipment is particularly important.
Documentation linked to, for example, CE and PED may be available depending on the design and previous use of the object.
Applications in industry
– Food industry – storage and process fluids
– Chemical industry – chemicals and process solutions
– Pharmaceutical production – hygienic processes
– Water treatment – buffer and chemical tanks
Second-hand tanks are often used where fast delivery and cost efficiency are prioritized.
Technical options and equipment
Used tanks can be equipped with:
– Agitators and mixing equipment
– Spray balls and CIP systems
– Level and temperature sensors
– Insulation and heating systems
– Valves and process connections
– PLC or SCADA customization
Design and equipment vary depending on the model and previous use.
Volumes and capacity
Used tanks come in many different sizes depending on availability and application.
The volume affects, among other things:
– Installation and transportation
– Process capacity and batch size
– Foundation and support structure requirements
– Integration into existing process plant
Advantages of second-hand tanks
– Lower investment cost
– Shorter delivery times
– Possibility of reusing industrial components
– Availability of a wide range of sizes and designs
– Possibility of conversion and technical adaptations
New and used tanks in stock
Process surplus offers both new and used tanks in various sizes and designs.
Inventory management may include:
– Process and storage tanks
– Vertical and horizontal tanks
– Pressure vessels and vacuum tanks
– Tanks with agitators and CIP equipment
Availability and documentation vary depending on the site and previous use.
Choosing the right used tank
When choosing a used tank, consideration should be given to:
– Chemical environment of the process
– Temperature and pressure requirements
– Hygiene requirements and cleaning needs
– Material selection and corrosion risk
– Available documentation and specification
Proper control and assessment is important for safe and long-term operation.
Executive summary
Used stainless steel tanks can be safe in the process industry if they are suitable for the current application and if the design, material and condition meet the requirements of the process. Process Surplus offers used 304 and 316 stainless steel tanks in several different designs depending on the process and application.
