We offer Fitness-for-Service (FFS) assessments in accordance with ASME code guidelines, providing engineering evaluations to determine the structural integrity of components experiencing degradation or damage. Our approach ensures reliable decision-making on continued operation, repair, or replacement—aligned with industry best practices and safety standards.

All vessels tested are returned with a complete test report.

Our Intermediate service package provides essential maintenance to ensure ongoing performance and safety of your pressure vessels. The service includes a thorough visual inspection to assess general condition and identify any visible signs of wear or damage. Key wear components and consumables, such as O-rings and gaskets, are replaced as standard.

We also carry out rupture disc replacement, and where applicable, perform crack pressure testing of the pressure relief valve to verify correct function. A final pressure test and leak check confirms system integrity before return to service.

Each serviced vessel is supplied with a comprehensive service report, documenting all activities, findings, and replaced components to support traceability and compliance.

Want to tweak this for specific pressure classes, materials, or turnaround timeframes? I'm ready when you are.

We provide comprehensive service and refurbishment for intermediate pressure vessels, ensuring continued reliability and regulatory compliance. Each vessel undergoes a systematic disassembly, followed by a thorough cleaning and degreasing process to remove operational residue. A detailed visual inspection identifies any signs of wear, corrosion, or damage.

All wear components and consumables, including O-rings, gaskets, and seals, are replaced with OEM or approved equivalents. The rupture disc is renewed as standard, and, where applicable, the pressure relief valve undergoes a crack pressure test to confirm functional integrity.

Following inspection and part replacement, vessels are reassembled using appropriate anti-seize compounds and PTFE tape on threaded joints, in line with service best practices. A hydrostatic or pneumatic pressure test is performed to validate leak-free performance.

Upon completion, each vessel is returned with a comprehensive service report documenting all actions taken, component replacements, and test outcomes.

Our on-site service provides rapid identification and repair of leaks to minimise downtime and maintain operational safety. The process begins with a visual inspection to assess the vessel’s general condition, followed by a pressure test and targeted leak detection, using either customer-supplied gas or FPE-supplied gas (available as a chargeable extra by prior agreement at booking).

Where leaks are identified, repairs are carried out using existing parts wherever possible to reduce cost and lead time. If new components are required, these will be fitted as needed and charged separately, subject to customer approval.

This convenient on-site solution ensures minimal disruption to your process, and each visit concludes with a summary report detailing findings, repairs, and recommendations.

Contains all of the testing performed in the intermediate service, while at the customer site.

Pressure tests to be performed using either customer-supplied inert gas or FPE-supplied inert gas (available as a chargeable extra by prior agreement at booking).
