Every pressure vessel and boiler begins with verified raw materials.
Our inspection includes:
- Material chemical composition analysis
- Thickness and hardness measurement
- Verification of Q345R, 20#, and alloy materials
- Checking steel plate surface integrity
Only materials that meet national standards enter production.
2.Henan Taiguo Boiler Quality Inspection Team make Welding Quality Assurance
Welding is the core of boiler manufacturing. We implement:

This ensures strong, durable, and safe welds.
3. Henan Taiguo Boiler Quality Inspection Team make Precision Manufacturing Inspection
Our quality team performs dimensional checks such as:
- Cylinder roundness
- Shell thickness
- Tolerance verification
- Alignment and level precision
- Door and flange accuracy for autoclaves
Every part is inspected before assembly.
4. Henan Taiguo Boiler Quality Inspection Team make Nondestructive Testing (NDT)
TAIGUO uses advanced testing methods to ensure structural safety:
- Ultrasonic Testing (UT)
- Radiographic X-ray Testing (RT)
- Magnetic Particle Testing (MT)
- Penetrant Testing (PT)
These tests detect internal or surface defects that cannot be seen with the naked eye.
5.Henan Taiguo Boiler Quality Inspection Team make Hydrostatic & Functional Testing
Before delivery, every boiler and autoclave undergoes:
- Hydrostatic pressure test
- Air-tightness test
- Safety valve calibration
- Combustion system test (for boilers)
- Electrical and PLC system verification
- Thermal efficiency test (for steam/hot-water boilers)
This guarantees safe and stable operation.
International Standards and Certifications
TAIGUO strictly follows:
- ISO9001 Quality Management System
- CE certification requirements
- National boiler & pressure vessel standards
- Environmental and safety compliance standards
Every QC record is traceable to ensure transparency and reliability.
Final Inspection & Delivery Approval
Before shipment, the Quality Inspection Team conducts a final comprehensive check:
- Exterior coating and anticorrosion quality
- Packaging protection for transportation
- Document completeness (pressure test reports, QC records, certificates)
Only equipment that meets 100% of quality requirements receives the TAIGUO approval stamp.
Why TAIGUO’s Quality Inspection Team Stands Out
- Fully independent QA/QC department
- Strict multi-stage inspection system
- Certified inspectors with decades of experience
- Advanced NDT and testing equipment
- Zero-defect mindset
- Reputation for reliability in 90+ countries
