Factory Acceptance Test Checklist for Bitumen Equipment Before Shipment

For overseas bitumen-equipment projects, discovering a problem after the equipment arrives on site is expensive. A missing valve, incorrect motor voltage, damaged instrument, unverified control sequence, or undocumented interface can delay installation by days or weeks.

A Factory Acceptance Test (FAT) gives the buyer and manufacturer a structured opportunity to verify the equipment before it is packed and released for shipment. The objective is not simply to “see the machine running.” A useful FAT confirms that the delivered scope matches the approved documents and that critical mechanical, electrical, control, heating, and safety functions have been checked.

1. Freeze the Approved Scope Before FAT

The FAT should be based on approved project documents rather than sales brochures. Before the test, confirm the latest revision of the purchase specification, general arrangement, P&ID or piping schematic, electrical drawings, equipment list, instrument list, and approved deviations.

If the buyer and supplier are testing against different revisions, the FAT can create more confusion instead of reducing risk.

2. Prepare an FAT Procedure and Inspection Record

The FAT procedure should identify each inspection item, acceptance criterion, test method, responsible party, and required record. Mark items as pass, fail, not applicable, or pending site verification.

For functions that cannot be fully tested in the factory—such as performance with the customer’s actual bitumen, site thermal oil network, or final field piping—the procedure should clearly state how and when they will be verified later.

3. Mechanical and Dimensional Inspection

Start with the physical equipment. Check model, quantity, major dimensions, nozzle positions, access platforms, lifting points, maintenance clearances, tank orientation, skid arrangement, and major purchased components against approved drawings.

For modular systems, confirm match marks and interface labels so that sections can be reassembled correctly at the destination.

4. Tank and Fabrication Checks

For bitumen storage tanks, melting chambers, and process vessels, review the agreed fabrication and inspection records. Depending on the project specification, this may include material identification, welding records, visual inspection, dimensional checks, leak testing, insulation arrangement, manholes, drains, overflow connections, and level-instrument locations.

The applicable test pressure and method should follow the approved design and project procedure. Do not apply an arbitrary pressure test to equipment that was not designed for it.

5. Heating-System Verification

Bitumen equipment is highly dependent on reliable heating. Inspect thermal oil coils, jackets, burner assemblies, electric heaters, circulation pumps, valves, expansion connections, temperature sensors, and insulation interfaces.

Functional checks may include pump rotation, burner ignition sequence, electric-heater interlocks, temperature-control logic, over-temperature protection, and thermal-oil circulation where the factory test setup permits.

If the package relies on an external thermal oil boiler supplied by the buyer, verify the required inlet and return conditions and clearly identify the site connection points.

6. Bitumen Pump and Piping Checks

Check pump model, flow direction, motor data, coupling guard, heating arrangement, suction and discharge orientation, valve accessibility, filter position, drain points, and circulation or reverse-pumping connections where included.

Confirm that arrows and line tags match the approved process drawing. Incorrect flow direction markings are simple to fix at the factory and frustrating to diagnose during commissioning.

7. Electrical Panel Inspection

Verify supply voltage, frequency, control voltage, motor ratings, cable entries, terminal labels, breakers, contactors, overload protection, grounding points, panel ventilation, and spare terminals according to the project scope.

Check that field devices and motors are tagged consistently with the drawings and PLC/HMI references.

8. PLC, HMI, Alarm, and Interlock Tests

For automatic systems, the FAT should demonstrate the intended control philosophy. Typical checks include:

• Manual and automatic modes
• Start/stop sequences
• Emergency-stop response
• Motor permissives and interlocks
• Low/high temperature alarms
• Level alarms where included
• Pump and heater protection logic
• Sensor-failure indication
• HMI status and alarm messages
• Communication signals required by the customer

For safety, simulated inputs are often used to prove logic without creating hazardous factory conditions.

9. Instrument Verification

Confirm that temperature, pressure, level, flow, and other instruments match the approved list and range. Review calibration certificates if specified. Verify mounting location, accessibility, tag numbers, and signal type.

10. Functional Test of Moving Equipment

Where applicable, operate conveyors, screw feeders, hydraulic tipping devices, agitators, pumps, hoists, doors, and other moving mechanisms under safe factory conditions.

Observe abnormal noise, vibration, direction of rotation, limit-switch response, guard installation, and emergency-stop function.

11. Safety and Maintainability Review

Inspect guards, hot-surface warnings, emergency stops, access ladders, platforms, handrails, lifting points, maintenance space, drain locations, and isolation valves. A machine can pass a basic functional test and still be difficult to operate safely if access is poor.

12. Documentation Review

The FAT should include a document-status check. Typical handover documents can include:

• Approved general arrangement drawings
• Foundation and load information
• Piping or process diagrams
• Electrical drawings
• PLC/HMI backups where contractually included
• Motor and instrument lists
• Operating and maintenance manuals
• Recommended spare-parts list
• Test and inspection records
• Packing list

13. Create a Punch List

Any incomplete or non-conforming item should be entered into a punch list with an owner, target date, and closure evidence. Classify which items must be closed before packing and which can be closed before shipment or at site by agreement.

Do not rely on verbal promises. A clear punch list protects both buyer and supplier.

14. Shipment Release

After the FAT and punch-list closure, confirm preservation, packing method, loose-item identification, spare-parts packing, lifting marks, center-of-gravity information where required, and shipping documentation.

Photograph major equipment, interfaces, loose parts, and container loading before dispatch. These records are useful during arrival inspection and installation.

What a FAT Does Not Replace

A factory test cannot fully reproduce the customer’s final installation. Site foundations, interconnecting pipelines, actual thermal oil, utilities, ambient conditions, bitumen properties, and integration with the asphalt plant still need commissioning verification.

The FAT reduces avoidable defects before shipment; site commissioning confirms that the complete installed system works under project conditions.

Conclusion

A strong FAT is a controlled comparison between the manufactured equipment and the approved project scope. Mechanical inspection, heating functions, pumps, controls, instruments, safety systems, documents, and shipment readiness should all be reviewed before the equipment leaves the factory.

FEITENG can prepare project-specific FAT documentation for bitumen storage tanks, melting machines, thermal oil systems, PMB equipment, emulsion plants, and complete bitumen-handling packages. Buyers can also provide their own inspection checklist or third-party inspection requirements during the RFQ stage.
