Dynamic sizing
Usable volume is calculated from inflow, outflow, disturbance duration, level limits and allowable pressure variation.
Stable flow between process steps
Stainless Steel Pressure Buffer Tank
A compact pressurised buffer vessel used to decouple equipment, stabilise flow and provide controlled process hold-up.
Quick answer
What this equipment is designed to do.
A stainless steel pressure buffer tank adds controlled hold-up between process steps. It can dampen short-term flow variation, reduce pump cycling, separate batch and continuous equipment, or maintain a stable feed condition when correctly sized and controlled.
Useful buffer volume depends on the actual disturbance: pump behaviour, upstream batch discharge, downstream demand, control-valve response or gas compression. Oversizing may increase residence time and cleaning burden.
Vessentra sizes the vessel together with level range, gas space, pump duty, minimum retention, inlet momentum, outlet requirements and skid controls.

Engineering configuration
Configured around your duty.
The equipment is developed from process inputs, operating conditions, cleaning requirements and site interfaces.
Hydraulic arrangement
Inlet, outlet, gas space and momentum control are coordinated to avoid entrainment, vortexing and unstable response.
Instrumentation
Level, pressure, alarms, control valves and pump interlocks are selected from the operating philosophy.
Skid integration
Vessel supports, pumps, valves, piping, drains, access and control enclosure are developed as one maintainable package.
Specification guidance
Define the operating basis before fabrication.
Project limits are confirmed through engineering review. These fields describe the decisions needed for an accurate, application-specific configuration.
| Buffer duty | Defined from process disturbance and control objective |
|---|---|
| Usable volume | Sized between agreed operating level limits |
| Design conditions | Project-defined pressure, temperature and vacuum cases |
| Product-contact material | Stainless steel selected for service |
| Gas space | Process gas or inert-gas arrangement as required |
| Instrumentation | Level, pressure, alarms and interlocks by control basis |
| Integration | Standalone vessel or complete process skid |
| Cleaning and drainage | Configured for the product and installation |
Common questions
Answers for project planning.
How is a pressure buffer tank sized?
Sizing starts with flow profiles, disturbance duration, usable level range, gas-space behavior, pressure limits and control response rather than a fixed percentage of line capacity.
Is a buffer tank the same as a storage tank?
No. A buffer tank is normally sized for short-term process stability, while a storage tank is sized for inventory.
Can pumps and controls be supplied on the same skid?
The vessel can be integrated with project-selected pumps, valves, instruments, piping and a local control panel when included in the package scope.
Can a sanitary buffer tank operate under pressure?
Yes, when pressure is part of the design basis and all hygienic connections, instruments, seals and safeguards are rated for the service.
