Quality Control in High Pressure Piping Systems
By its nature, high pressure piping requires the strongest level of quality control. Failures of high-quality piping can be catastrophic, and even small defects could seriously compromise the integrity of the piping system. This is also true for large bore pipe fabricators, who must meet stringent qualifications and certifications. That’s why STI Group utilizes a rigorous, comprehensive quality control program that includes the following components:
- Inspection and Testing (CWIs in every facility)
- Policy and Authority
- Organization standards
- Testing Requirements
- Duties and Responsibilities
- Code Stamp Control
- Document Control
- Calibration
- Record Retention
- Comprehensive MTR Program
