Three aspects summarize the quality inspection of stainless steel reactors

When a customer receives a stainless steel reactor manufactured by our company, we conduct a comprehensive inspection to ensure its quality and prevent issues during installation and operation. The inspection process includes the following steps:

1. **External Inspection**:

- Check for abnormalities such as cracks, deformation, leaks, or localized overheating on the reactor body.

- Verify the completeness, sensitivity, and reliability of safety attachments.

- Ensure fastening bolts are intact and fully tightened.

- Inspect the foundation for sinking, tilting, or damage to the anti-corrosion coating.

- This inspection is part of the operator's routine checks and should also be conducted annually by container inspectors.

2. **Internal and External Inspection**:

- Examine the reactor's internal and external surfaces for corrosion, wear, and stress-related issues.

- Inspect all welds, excessive head areas, and other stress-concentrated areas for cracks using the naked eye or magnifying glass.

- Use ultrasonic or radiographic testing if necessary to assess weld quality.

- Measure wall thickness; if it is below the minimum required, perform metallographic inspection.

3. **Comprehensive Inspection**:

- Includes external and internal inspections.

- Conduct a pressure test and, depending on the reactor's characteristics, perform non-destructive testing (NDT) on key welds.

- For low-pressure reactors containing non-flammable, non-toxic, and non-corrosive media with no defects, NDT may be omitted after a certain period of use and inspection.

These inspections ensure the reactor's safety, reliability, and compliance with quality standards before it is put into service.
