Pressure Vessels
Single Wall Tanks
KAF Cryogenics provides pressure vessels and industrial storage solutions for process plants, manufacturing facilities, energy projects, chemical applications and utility systems. The range includes process vessels, air and gas receivers, refrigerant tanks, API storage tanks, spherical tanks and custom-designed vessels.
Design code selection follows the service condition: vessels operating above 0.5 bar(g) are typically designed to ASME Section VIII Division 1 or EN 13445, while atmospheric and low-pressure bulk storage tanks, the API storage tanks in the range, are designed to API 650 or API 620 as applicable. Spherical tanks, commonly used for large-volume storage of propane, butane, LPG, ethylene and similar liquefied gases, are designed to AD 2000 Merkblatt or ASME (U or U2 stamp) as applicable; their shape distributes pressure-induced stress evenly across the shell, favoring large-capacity, high-pressure storage duties. Each vessel is configured around project-specific capacity, pressure, design temperature, material and nozzle requirements, with vertical, horizontal and spherical configurations available and carbon steel or stainless-steel material options selected according to the intended process service.
Where required, equipment can be configured with project-specific nozzle layouts, surface finish or coating requirements and instrumentation provisions. Each vessel is hydrostatically pressure tested, typically at 1.3 times the maximum allowable working pressure, before dispatch, and applicable design codes, documentation, material certification and inspection requirements, including third-party inspection and stamping where specified, are agreed as part of the project scope.
Frequently Asked Questions
What types of pressure vessels are available?
The range includes process vessels, air and gas receivers, refrigerant tanks, API storage tanks, spherical tanks and custom-designed vessels.
Which design code applies to which vessel type?
Vessels operating above 0.5 bar(g) are typically designed to ASME Section VIII Division 1 or EN 13445; atmospheric and low-pressure bulk storage tanks are designed to API 650 or API 620. The applicable code is confirmed from the operating pressure, service and destination.
Can pressure vessels be designed for project-specific capacities and pressures?
Yes. Capacity and pressure are defined per project together with design temperature, material selection and the required vessel configuration.
Which configurations and materials are available?
Vertical, horizontal and spherical configurations are available, with carbon steel and stainless-steel options depending on the application. Spherical tanks, typically used for large-volume storage of propane, butane, LPG and similar liquefied gases, are designed to AD 2000 Merkblatt or ASME (U/U2 stamp) as applicable.
Can nozzle layout and instrumentation be customized?
Yes. Nozzle arrangements, instrumentation provisions and surface or coating requirements can be defined according to the project specification.
How are design codes and documentation handled?
The applicable design code and required documentation are confirmed for the specific project and destination. Recognized pressure-equipment design codes and project-specific certification requirements can be addressed according to the agreed scope.
Is third-party inspection and stamping available?
Third-party inspection and stamping requirements, ASME U-stamp can be coordinated as part of the project scope where required by the destination or specification. All manufacturing stages is under inspection of TUV Austria.
