When you receive a shipment from carilovalves, the documentation package that accompanies your industrial ball valves goes far beyond a simple packing slip. Every shipment includes a comprehensive set of quality documents designed to provide full traceability, compliance verification, and operational confidence for engineers and procurement specialists worldwide. Based on our extensive experience working with industrial valve buyers across Europe, the Middle East, and Southeast Asia, these documents represent the documented proof of our manufacturing excellence and the 24+ years of expertise Zhejiang Carilo Valve has accumulated since our founding in 2000.
Core Quality Documentation Package
The primary documentation that accompanies every Carilovalves shipment consists of several essential components that together form a complete quality assurance package. Our quality control team, working alongside our dedicated staff of 50 professionals, ensures that each documentation set reflects the actual testing performed on the specific valves in your shipment.
| Document Type | Purpose | Applicable Standards |
|---|---|---|
| Inspection Certificate | Confirms dimensional accuracy and visual compliance | ASME B16.34, API 598 |
| Pressure Test Report | Documents hydrostatic and pneumatic test results | API 598, ISO 5208 |
| Material Certificate | Verifies chemical composition and material traceability | EN 10204 3.1, ASTM A105 |
| Certificate of Conformity | Declares compliance with specified requirements | ISO 9001:2015 |
| Test Log Sheet | Records real-time monitoring data during testing | Internal QC-201 |
Pressure Testing Documentation Details
Every industrial ball valve from Carilovalves undergoes 100% pressure testing before shipment, and this testing generates detailed documentation that clients receive with their orders. Our testing procedures follow stringent protocols that exceed minimum industry requirements, with documentation including shell test pressures, seat test pressures, and leak detection results.
“The pressure test report we received showed readings of 1.5x rated pressure for shell testing and 1.1x for seat testing, with zero leakage detected across all test cycles. This level of detail gave our engineering team complete confidence in the valve performance before installation.”
The pressure testing documentation includes specific data points such as test medium (typically water or nitrogen depending on valve type), test duration (minimum 60 seconds per test phase), acceptance criteria applied, and the actual test equipment serial numbers used. This traceability ensures that if any performance questions arise during installation or operation, the complete testing history is available for review.
Material Verification and Traceability
Our material certificates provide full traceability from raw material suppliers through finished valve production. For carbon steel valves, we provide EN 10204 3.1 type material certificates documenting the heat number, chemical analysis results, and mechanical properties of the body, ball, stem, and seat materials. This documentation proves particularly valuable for projects in the oil and gas sector where material traceability is mandatory for compliance purposes.
- Body and Bonnet Materials: Chemical composition report with carbon, manganese, silicon, phosphorus, sulfur, chromium, molybdenum, and nickel content
- Ball and Stem Materials: Hardness testing results and surface finish specifications
- Seat and Seal Materials: Material identification, Shore hardness readings, and temperature range verification
- Bolting Materials: Grade identification and traceability to mill test reports
Industry Certification Documentation
Carilovalves maintains globally recognized certifications that are documented in your shipment package. Our ISO 9001:2015 quality management system certification covers all manufacturing processes, and copies of relevant certificates are included with international shipments.
