What is a pressure vessel compared to a standard tank?
A pressure vessel is a tank or container designed to handle internal pressure variations during operation, whereas a standard tank is usually used in atmospheric conditions without specific pressure resistance requirements.
Pressure vessels are used in processes where liquids or gases need to be stored, processed or transported under controlled pressure conditions depending on the process and application.
Processöverskott offers both new and used stainless steel pressure vessels and standard tanks in stainless steel 304 and acid-proof 316 in different sizes and designs depending on specification and application.
Function and structure
A pressure vessel is designed to handle internal pressure levels and therefore may have different design solutions than a standard tank.
Pressure vessels often have reinforced walls, special welding designs and pressure management components depending on the design and classification.
Standard tanks are often used for the storage of liquids at atmospheric pressure and usually have a simpler design depending on the application.
Both pressure vessels and standard tanks can be equipped with, for example, agitators, level measurement, inspection hatches and CIP systems depending on the specification and process requirements.
Materials and construction
Pressure vessels and standard tanks are often manufactured in stainless steel 304 or acid-proof 316 depending on the properties of the fluid and the requirements of the process.
Stainless steel is used in many industrial applications where cleanability and resistance to corrosion are relevant factors.
Pressure vessels may have different requirements on, for example, wall thickness, reinforcements and weld design compared to standard tanks depending on operating conditions and specification.
Surface treatment and design vary depending on the application and process requirements.
Pressurized and atmospheric solutions
Pressure vessels are used in processes where pressure conditions are part of the operation and can be designed for positive or negative pressure depending on the application.
Standard tanks are often used in atmospheric conditions where pressure management is not a central part of the process.
Pressure vessels may be equipped with components such as safety valves, pressure measurement and other safety-related solutions depending on the design and specification.
Documentation linked to, for example, PED and CE may be available where it is relevant to the design and classification of the tank.
Applications in industry
Pressure vessels and standard tanks are used in several types of industrial processes.
Examples of applications include food production, chemical industry, pharmaceutical related processes and water treatment depending on the properties of the fluid and the requirements of the process.
Pressure vessels are often used in processes where pressure, temperature or gas formation needs to be managed while standard tanks are usually used for storage or simpler process management.
Technical options and equipment
Tanks and pressure vessels may be equipped with, for example:
Safety valves and pressure measurement
Agitators and mixing equipment
Temperature-related solutions such as sheathing or insulation
Inspection hatches and level measurement
CIP system for cleaning
Valves and process connections
Pressure monitoring and safety-related functions
The design varies depending on the model, specification and application.
Volume and capacity
Pressure vessels and standard tanks come in many different sizes depending on the process and capacity needs.
Smaller vessels are used, for example, in pilot processes and laboratory environments, while larger tanks are used in production facilities with larger flows and batches.
Volume can influence factors such as construction, wall thickness, safety equipment and the need for peripherals depending on the application.
Advantages of pressure vessels
Pressure vessels are often used in processes where pressure management is part of the operation and where process conditions require specific design solutions.
The design can allow integration with different technical solutions depending on process requirements and operating conditions.
New and used pressure vessels
Processöverskott offers both new and used pressure vessels and standard tanks in various designs and sizes.
Tanks may be equipped with different technical solutions depending on the model and previous use. Availability varies depending on stock status and specification.
Choosing the right solution
The choice of pressure vessel or standard tank is often based on factors such as the characteristics of the liquid, pressure level, temperature, hygiene requirements and process requirements.
Process surplus can provide information on different designs and technical options depending on the application and area of use.
Executive summary
A pressure vessel differs from a standard tank in that it is designed to handle internal pressure variations during operation.
Process Surplus offers stainless steel pressure vessels and standard tanks in various designs where technical solutions such as pressure monitoring, stirring, CIP and temperature-related functions may be present depending on the specification and application.
