At Henan Taiguo Boiler Manufacturing Co., Ltd., quality is not just a standard—it is a commitment. Our Strict Quality Inspection Team ensures that every boiler, autoclave, and pressure vessel meets the highest levels of safety, performance, and reliability before leaving our factory.
With more than 45 years of manufacturing experience, TAIGUO has built a fully integrated Quality Assurance (QA) and Quality Control (QC) system supported by highly trained inspectors, advanced testing equipment, and internationally recognized standards.
A Professional, Certified Inspection Team
TAIGUO’s quality department consists of over 20 certified inspectors, including:
- Nationally certified nondestructive testing (NDT) engineers
- Welding quality inspectors
- Pressure vessel inspection experts
- Material quality analysts
- Dimensional and tolerance inspectors
- Safety compliance engineers
Our inspectors hold certifications such as:
- UT, RT, PT, MT NDT licenses
- Welding inspection qualification
- ISO9001 internal auditor certificates
- National pressure vessel inspection training
Comprehensive Quality Control System
Our quality inspection process covers each stage of production to ensure zero defects and full compliance.
1. Raw Material Inspection
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. Welding Quality Assurance
Welding is the core of boiler manufacturing. We implement:
- Qualified welder testing
- Welding procedure specifications (WPS/PQR)
- Real-time welding parameter monitoring
- Visual inspection of weld seams
- Nondestructive testing of critical joints
This ensures strong, durable, and safe welds.
3. 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. 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. 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
