Design pressure and working pressure in pressurized tanks
Design pressure and working pressure are two concepts used in the design and classification of pressurized tanks and pressure vessels in industry.
Working pressure refers to the pressure at which the tank is normally used under operating conditions, while design pressure is used as a design parameter in the dimensioning and classification of the tank.
The design pressure is usually higher than the working pressure to allow for safety margins, temperature variations and operating conditions depending on the application and regulations.
Processöverskott offers both new and used pressure vessels in various designs where documentation linked to, for example, working pressure, design pressure, PED and CE may be present depending on specification and previous use.
Function and structure
When designing pressurized tanks, several factors are taken into account depending on the process and application.
Examples of parameters that can influence the dimensioning are
Choice of materials such as stainless steel 304 or acid-proof 316/316L
Plate thickness and reinforcements
Temperature and operating conditions
Pressure level and safety margins
Connections, stirrers and internal equipment
Tanks can also be equipped with, for example, level measurement, safety valves and pressure monitoring depending on the design and specification.
Materials and construction
Pressurized tanks are often manufactured in stainless steel 304 or acid-proof 316 depending on the properties of the liquid and the requirements of the process.
Material properties can affect, for example, strength, corrosion resistance and construction depending on temperature and operating conditions.
Tanks are usually welded and may have different surface treatments such as grinding or polishing depending on the application and requirements of the process.
Documentation related to materials, weld design and possible tests may occur depending on the specification and regulatory requirements.
Pressurized and atmospheric solutions
Design pressure and working pressure are mainly relevant for pressurized systems and pressure vessels depending on the design and application.
Atmospheric tanks are often used in processes where pressure conditions are not relevant and are normally not subject to the same requirements related to pressure equipment.
Pressurized tanks may be equipped with components such as safety valves and pressure gauges depending on the design and specification.
Applications in industry
Pressurized tanks are used in several types of industrial processes.
Examples of applications are food production, chemical industry, pharmaceutical related processes and water treatment where pressure management can be part of the process.
Usage varies depending on process requirements, fluid properties and operating conditions.
Technical options and equipment
Tanks can be equipped with, for example:
Pressure measurement and monitoring
Safety valves
Inspection gaps and sampling points
Agitators and processing equipment
Temperature-related solutions such as sheathing or insulation
Valves and process connections
The design varies depending on the model, specification and application.
Volume and capacity
Pressure vessels come in many different sizes depending on the process and capacity needs.
Volume can influence factors such as construction, wall thickness, safety equipment and documentation needs depending on the application and operating conditions.
Documentation and testing
For pressurized tanks, documentation and different types of testing may occur depending on the classification, specification and application.
This may involve, for example, material documentation, welding-related tasks and various types of inspection or testing depending on current requirements and regulations.
New and used pressure vessels
Processöverskott offers both new and used pressure vessels in various designs where documentation linked to, for example, working pressure, design pressure, PED and CE may occur depending on the object and specification.
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
Pressure vessel selection is often based on factors such as pressure level, temperature, fluid properties and process requirements.
Process surplus can provide information on different designs and technical options depending on the application and area of use.
Executive summary
Design pressure and working pressure are used in the design and classification of pressurized tanks and pressure vessels in industry.
The working pressure refers to the pressure at which the tank is used under normal operating conditions, while the design pressure is used as a design parameter taking into account safety margins and operating conditions.
Processöverskott offers stainless steel pressure vessels in various designs where documentation and technical solutions may occur depending on the specification and application.
