Product Details

Residual Stress Indentation Tester – PMA-1010 for Storage Tank Weld Inspection

URL Slug: residual-stress-tester-storage-tank-weld

Product Summary

Model PMA-1010 is a portable nondestructive indentation tester designed to measure welding residual stress in large storage tank bottom plates. It offers dual-parameter (hardness and residual stress) on-site testing, aiding in weld quality control and preventing failure.

Key Features

Weld Stress Measurement: Specifically designed for tank bottom plate welds.
Dual-Parameter Testing: Simultaneously measures hardness and residual stress.
High Load Capacity: 1000 N maximum load for robust testing.
Fast Data Acquisition: 100 Hz rate for detailed weld stress profiles.
Portable Design: Easy to move around large tanks.
