Product Details

Residual Stress Indentation Tester – PMA-1010 for Cold-Worked Fittings

URL Slug: residual-stress-tester-cold-work-fittings

Product Summary

Model PMA-1010 is a portable nondestructive indentation tester that measures cold-work induced residual stress in stainless steel elbows and tees. This helps prevent stress corrosion cracking in petrochemical piping systems.

Key Features

Cold-Work Stress Detection: Measures stress introduced by cold forming processes.
Corrosion Prevention: Identifies areas prone to stress corrosion cracking.
Portable & Compact: Ideal for tight spaces like elbows and tees.
Wide Load Range: Up to 1000 N for various materials.
Fast Analysis: 100 Hz data rate for rapid assessment.

FAQ

Q: What is cold-work stress?
A: Stress generated during cold forming processes like bending or forging.

Q: How does it prevent cracking?
A: By detecting high-stress zones that could lead to stress corrosion cracking.

Q: Can it be used on curved surfaces?
A: Yes, with appropriate indenters.

Q: What is the testing time per point?
A: Very fast due to high loading speed.

Q: Does it require calibration?
A: Yes, periodic calibration is recommended as per manual.
