Our Commitment to Quality
Our Own Biggest Critics -- Us
The goal at STW is simple: no product leaves our facility without being thoroughly tested for proper fit, operation and safety:
- Non-destructive testing using X-ray, magnetic particle, helium leak, dye penetrant and trace element testing (mass spectrometer).
- Hydrostatic and pneumatic pressure testing to 12,000 PSI
- Laser testing for column and nozzle alignment
- In-house metallurgical lab for destructive and non-destructive testing.
