Who this service is for
Owners and operators of vessels, boiler plants and process installations; manufacturers and repair organizations requiring acceptance or post-repair checks.
When it is required
Valve checks cover operation, setting and tightness under the documentation and applicable rules. Vessel work includes the prescribed strength and leak tests. Requirements and intervals depend on intended use, working medium, design, passport and operating conditions. These checks must be distinguished from metrological verification of measuring instruments, which is a separate procedure.
What to prepare
- Vessel or valve passport, manufacturer markings, intended use and installation location.
- Operating and design pressure, temperature, medium and volume; valve set pressure and discharge capacity.
- Design documents, installation diagram, previous test reports and repair records.
- Requirements for acceptance of the test report, any need for an accredited laboratory, the test location or possibility of removal.
How we work
- Select an applicable test program and competent provider.
- Agree on preparation, isolation, cleaning and safe transport or a site visit.
- Verify the suitability of test equipment and measuring instruments.
- Perform the tests and record actual measurements and defects.
- Issue the test report and required records; refer defective equipment for a repair or replacement decision.
What you receive
A test report, inspection or setting report, documentation entries and sealing where prescribed.
What to keep in mind
Test pressure and method are determined from the source data. Laboratory status and accreditation scope are checked for the specific task. A hydraulic pressure test does not replace the complete statutory inspection scope.
Price and timing
Price and timing depend on the number of items, available documentation and the need for calculations, site visits and testing. After an initial review, we agree on the scope, cost and schedule. Free government services are distinguished from preparation and support charges.
Questions about this service
Is safety valve testing a form of metrological verification?
Valve testing normally checks operation, setting and tightness. Metrological verification of measuring instruments is a different procedure; for example, it may be required for the pressure gauge used in testing.
How often must a pressure vessel undergo statutory inspection?
The interval is established from the manufacturer's documentation and applicable rules, considering the medium, design and operating conditions. One interval cannot be applied to every vessel.
