Industrial Hydrostatic Pressure Testing: Workshop & On-Site
Using specialist hydrostatic testing equipment with a capability of up to 500 bar, we support industrial clients, manufacturers and engineering contractors requiring controlled water pressure testing as part of fabrication, installation, maintenance and modification projects.
Testing is planned according to the component design, applicable specifications, agreed test pressure and site conditions.
Industrial Hydrostatic Pressure Testing
Hydrostatic testing is a method of assessing the pressure integrity of suitable components and systems by filling them with water, removing trapped air and applying a controlled test pressure.
It is commonly undertaken to check for leakage and demonstrate pressure integrity against defined acceptance criteria.
AEWS can provide hydrostatic testing services for suitable applications including:
Industrial process pipework
Fabricated pipe spools
Welded pipework assemblies
Pipework modifications and replacement sections
Selected pressure-containing components
Suitable fabricated vessels and assemblies, subject to specification and assessment
Industrial equipment connections and associated pipework
The suitability of each item for hydrostatic testing is established before work begins.
Testing Procedures and Inspection Records
Testing is carried out against agreed requirements rather than a universal pressure or hold period.
Depending on the application, the relevant project requirements may reference standards such as BS EN 13480-5 for metallic industrial piping or other applicable specifications.
Our testing arrangements can include:
Identification of the test item or system
Confirmation of the agreed test pressure
Review of component limitations and test boundaries
Suitable pressure instrumentation
Controlled filling, venting and pressurisation
Monitoring during the specified hold period
Inspection against agreed acceptance criteria
Recording of test results
The level of documentation supplied is established according to the project requirements.
Workshop Hydrostatic Pressure Testing
Where practical, fabricated pipework and assemblies can be pressure tested before delivery to site.
Workshop testing can help identify leakage or other issues before components are installed within an operating facility.
Our workshop testing services may include:
- Fabricated pipe spools and welded assemblies
- Replacement pipework sections
- Flanged and welded pipework connections
- Suitable fabricated components
- Testing following workshop modifications or repairs
Testing requirements are agreed before the work is undertaken.
On-Site Hydrostatic Pressure Testing
AEWS also provides on-site hydrostatic pressure testing for suitable industrial pipework and assemblies.
This can support newly installed pipework, plant modifications, replacement sections and shutdown projects.
On-site testing requires careful coordination with the client, particularly where existing systems, live plant, access restrictions or other contractors are involved.
Testing arrangements may include system isolation, filling, venting, controlled pressurisation, inspection, depressurisation and safe disposal or management of the test water.
Pressure Testing Following Welding and Fabrication
Hydrostatic testing can form part of the inspection and quality assurance arrangements for fabricated pipework and welded assemblies.
AEWS combines pipework fabrication, welding, installation and pressure testing services, allowing suitable projects to be coordinated through multiple stages.
Where specified, pressure testing can be undertaken after fabrication, repair or installation to assess the integrity of the completed pressure boundary.
Hydrostatic testing does not replace other inspection or examination methods where these are required by the applicable specification.
Safety During Hydrostatic Pressure Testing
Pressure testing involves stored energy and must be properly planned and controlled.
Before testing, consideration is given to the pressure boundary, component condition, temporary connections, restraints, isolation, exclusion zones and personnel access.
We also assess the consequences of leakage or component failure, including the potential release of pressurised water.
Where appropriate, testing is undertaken under project-specific risk assessments and method statements, with client permits and site procedures followed.

Frequently Asked Questions About Hydrostatic Pressure Testing
Hydrostatic pressure testing is a method of assessing the pressure integrity of suitable pipework, vessels and other pressure-containing components using a liquid, normally water. The component is filled, vented and pressurised to an agreed test pressure, then inspected and monitored according to the specified procedure and acceptance criteria.
AEWS has hydrostatic water pressure testing equipment with a capability of up to 500 bar. The pressure used for an individual test depends on the design and limitations of the component, the applicable specification and the agreed test procedure. Not every component or system is suitable for testing at 500 bar.
Yes. AEWS provides on-site hydrostatic pressure testing for suitable industrial pipework, fabricated assemblies and plant modifications. On-site testing is planned around system isolation, access, safety requirements, water management and the agreed testing specification.
Yes. AEWS can undertake hydrostatic pressure testing of suitable fabricated pipe spools, welded assemblies and other components at our workshop. Testing before delivery can help identify leakage or pressure integrity issues before installation.
Yes. Hydrostatic testing can be undertaken on suitable carbon steel and stainless steel pipework. The test arrangements depend on the material, design, applicable specification and service requirements. For stainless steel and other corrosion-sensitive applications, the suitability and quality of the test water, along with draining and drying requirements, may need particular consideration.
Yes. AEWS can provide hydrostatic pressure testing following suitable pipework fabrication, welding, repair or installation work. This allows testing to be coordinated with our fabrication and industrial pipework services. Any additional inspection or non-destructive examination requirements are established according to the project specification.
The duration depends on the size and complexity of the system, filling and venting arrangements, the required test pressure and the specified hold period. There is no single test duration suitable for every application. AEWS establishes the testing sequence and required hold period according to the agreed procedure and project requirements.
Yes. AEWS can provide pressure testing records and associated inspection documentation according to the agreed project scope. These may include identification of the tested item, test pressure, hold period, inspection observations and test result. Any specific certification, witnessing or independent verification requirements should be identified before testing.
The applicable standards depend on the type of component or system being tested. For example, BS EN 13480-5 addresses inspection and testing requirements for metallic industrial piping. Other systems or components may be subject to different standards, codes or client specifications. AEWS reviews the applicable requirements before establishing the test procedure.
