Describe the test duty, not only the maximum pressure.
A pressure-test system quotation becomes more useful when the supplier understands the workpiece and intended duty. State the equipment being tested, the required pressure range and the internal volume to be filled. Describe whether the package will work in a workshop, a field location or another defined installation.
Distinguish filling from pressure boosting.
Filling a large volume and reaching a high test pressure can involve different flow requirements. Provide the required flow at the relevant operating pressure. Do not assume that a pump’s maximum pressure and no-load flow occur together. Ask for the proposed duty point or performance information.
Prepare these RFQ details.
- Workpiece and duty: equipment type, volume, pressure range and expected use pattern.
- Medium: liquid or gas, composition, temperature and material/seal compatibility requirements.
- Utilities: electrical supply or compressed-air pressure and capacity.
- Instrumentation: measurement ranges, channels, accuracy, calibration and test-report requirements.
- Physical scope: skid, reservoir, valves, relief arrangements, hoses, connections, enclosure and handling requirements.
- Project controls: site environment, remote operation, inspection and acceptance requirements.
Make the supply boundary explicit.
A pumping skid is not automatically a complete test facility. Identify the workpiece handling, containment, barriers, control location and other site provisions required by the project. The actual test method and acceptance criteria should come from the applicable equipment requirements and responsible engineering review.
Ask for comparable quotations.
Request a list of included components, accessories, documents and exclusions. Clarify which values are guaranteed for the offered configuration and which are catalog reference figures.
