Pressure instrument inspections

Accurate gauges and well-maintained safety valves keep operations stable and free from ambiguity. Pressure instrument inspection from Control Union calibrates a wide range of gauges and surveys safety valves using specialised tools, so measurement reliability stays high and incident risk stays low across every pressure-critical process.

    Compliance and safety through pressure instrument inspection

    Control Union aligns calibration processes with ASME B40-100, which locks in the highest level of measurement accuracy and precision for every gauge. For pressure safety valves, periodic survey programmes follow API Standard 527 and API Recommended Practice 576, covering leak-rate testing and inspection intervals that satisfy regulatory obligations. Together, these standards give operators documented proof of compliance and a clear audit trail that holds up under scrutiny.

    How we work

    Towards control, insight, and certainty

    The strength lies in the combination of inspection expertise, advanced data systems, and global practical experience.

    Step 1

    Define the inspection scope together, tailoring the survey programme to specific client requirements and applicable standards.

    Step 2

    Inspectors carry out tablet‑based inspections on site, logging all measurements and findings to support prompt reporting.

    Step 3

    Calibration reports upload to a secure portal with search and storage functionality, giving permanent access to all certificates.
