Consulting and Drafting NDT Procedures
A non-destructive test is only as reliable as the procedure governing it. At High Technology Nondestructive Testing Service Co., Ltd, we provide specialized technical writing and consulting services to develop robust, code-compliant NDT procedures tailored to your specific project needs.
Our Procedure Development Services
We draft comprehensive Standard Operating Procedures (SOPs) and Technical Instructions for all major NDT methods, ensuring they are technically sound and audit-ready:
-
Advanced Technologies: Phased Array (PAUT), Time of Flight Diffraction (ToFD), and Digital Radiography (DR).
-
Specific Applications: Procedures for pipeline girth welds, structural steel, pressure vessels, and aerospace components.
Compliance with Global Standards
Our drafting process ensures 100% alignment with international regulatory bodies and industry codes, including:
-
ASME Section V (Nondestructive Examination)
-
ISO 9712 / EN ISO 17636 (Welding & NDT Standards)
-
AWS D1.1 / D1.5 (Structural Welding Codes)
-
API 1104 / API 5L (Oil & Gas Pipeline Standards)
Key Components of Our Procedures
When we draft a procedure, we cover every technical detail required for high-quality execution:
-
Scope & Personnel Qualification: Defining the required certification levels (Level II/III).
-
Equipment Calibration: Detailed instructions for sensitivity settings and calibration blocks.
-
Examination Parameters: Scanning speeds, focal laws, probe angles, and film types.
-
Acceptance Criteria: Clear “Pass/Fail” thresholds based on the applicable construction code.
-
Reporting Templates: Standardized forms for data recording and traceability.
The Level III Advantage
All procedures are drafted or reviewed by our ASNT/ISO Level III experts. This ensures that the techniques selected are the most efficient and accurate for your specific material geometry and alloy type, reducing the risk of “false calls” or missed defects.
