NDE Testing
RT, UT, MT, PT and PMI for valve components — in-house inspection with calibrated equipment.
- RT — Radiographic Testing · internal volumetric defects
- UT — Ultrasonic Testing · internal defects and thickness
- MT — Magnetic Particle · surface and near-surface cracks
- PT — Liquid Penetrant · surface-breaking defects
- PMI — Positive Material Identification · alloy verification
For material verification, defect detection and audit-ready reports.
Plan inspectionDocumentation Support
MTC, dimensional report, NDE report, ITP / TPI support — audit-ready files with revision control.
- Material Test Certificates (MTC)
- Dimensional inspection reports
- NDE inspection reports
- ITP — Inspection and Test Plans
- TPI — Third-Party Inspection support

Service Responsibility and Quality Control
CARILO service is operated from the same production campus where the valves are manufactured. Service outputs are reviewed, documented and controlled under the company quality system.
Organisation & accountability
Before You Send a Request
Quick boundary guide — confirm fit before submitting.
Spare parts and engineering support are primarily based on original production records. For valves with available manufacturing files, support is direct.
Accepted subject to drawing, sample and feasibility review. Original-spec guarantees apply only to CARILO-manufactured valves with available records.
Method, coverage, acceptance criteria and reporting format must be confirmed before quotation. Standards alone do not define the inspection scope.
Standard parts may be dispatched in 5–7 working days after order and commercial confirmation. Bespoke parts follow confirmed production schedule.
Witness scheduling and related costs are confirmed at quotation. Domestic and international TPI agencies are accepted.
Service requests are reviewed and acknowledged within one working day. Urgent spare-parts requests are flagged with priority routing from first contact.
Common Questions
Do you support valves manufactured by other brands?
Third-party valve support is subject to drawing, sample and feasibility review. CARILO can assess parts compatibility, material identification and reverse-engineering requirements, but original-spec guarantees apply only to CARILO-manufactured valves with available records.
What information is required to identify a spare part?
Please provide valve model, size, pressure class, serial number or original PO number, and the part name or description. Photos of the nameplate and damaged part can reduce identification time.
When is reverse engineering required?
Reverse engineering is required when no original drawings or production records exist. It usually requires a physical sample or detailed field measurements and is subject to engineering review and quotation.
Which NDE method should I choose?
The method depends on material, geometry, thickness, defect type and project acceptance criteria. RT and UT are commonly used for internal defects, MT and PT for surface defects, and PMI for material grade verification.
What documents are included with inspection or spare parts service?
Typical documents include quotation, part identification, packing list, dimensional report, MTC and NDE report when applicable. The final document package is confirmed before quotation.
Which services are free?
Existing datasheets, available drawings, installation guidance and initial troubleshooting based on submitted information may be provided at no charge. Reverse engineering, root-cause analysis, custom calculations, on-site service and repair procedures require quotation.
