Portable Nondestructive Weld Stress Tester – PMA-1010 for Thin-Wall and Pipe Girth Welds
The PMA-1010 is a portable weld stress tester optimized for thin-wall welds and pipe girth welds. It rapidly measures axial and hoop residual stresses on site, providing critical data for pipeline integrity assessments without introducing extra distortion or vibration.
Product Summary
This device is engineered for on-site evaluation of residual stresses in thin-wall structures (3mm) and pipe girth welds. It uses a non-destructive indentation method, creating indentations of only a few microns, thus preserving the weld integrity. Simultaneous measurement of axial and hoop stresses enables complete stress field characterization, supporting life assessment and failure analysis.
Key Selling Points
- Thin-Wall Forgiving: Suitable for thin-wall welds as thin as 3mm without introducing additional distortion or vibration, ensuring accurate readings.
- Rapid Pipe Girth Weld Analysis: Quickly measures axial and hoop residual stresses at pipe girth welds, enhancing on-site efficiency.
- Non-Destructive Method: Indentations of only a few microns do not affect subsequent NDT, preserving component integrity.
- Minimal Surface Prep: Insensitive to weld reinforcement or undercuts, saving time on complex geometries.
- Portable for Remote Sites: One-person operable, ideal for high-altitude or remote pipe inspection locations.
