Petrochemical Equipment Safety Evaluation Indentation Tester - Sour-Service Tower Weld Evaluation
Model PMT-1000 is a portable nondestructive indentation tester designed for minor-damage stress testing on sour-service tower welds. With maximum load of 1000 N and data acquisition rate of 100 Hz, it warns of cracking risk while quantifying safety loss from creep by comparing residual vs original strength. This intrinsically safe instrument meets petrochemical site rules for hazardous zones.
Key Selling Points
- Minor-Damage Stress Testing: Indentation depth of 60-120 μm minimizes surface impact while assessing weld integrity – ideal for in-service sour-service towers.
- Cracking Risk Warning: Identifies potential cracking in welds early through precise indentation measurements, supporting condition-based maintenance.
- Residual vs Original Strength Comparison: Quantifies safety loss after creep, providing data-driven insight into remaining equipment life.
- Intrinsic Safety for Hazardous Zones: Rated for hazardous areas, complies with petrochemical site rules, enabling safe on-site testing.
- Portable & Efficient: 25 mm actuation range and adjustable loading speed (0.01-30 mm/min) allow rapid multi-location testing without shutdown.

FAQ
What is the indentation depth and why is it considered minor-damage?
The indentation depth is 60~120 μm, which is very shallow, minimizing surface impact while still providing stress-strain data.
Can it be used in hazardous zones with flammable gases?
Yes, the tester is intrinsically safe and complies with petrochemical site rules, making it suitable for hazardous areas.
What is the maximum load capacity?
The maximum load is 1000 N, sufficient for most weld testing applications.
How fast can I get results?
With data acquisition at 100 Hz and loading speed adjustable up to 30 mm/min, results are obtained quickly, often in just minutes.
Does it require external power?
It supports both wired (220 V) and wireless (24 V) power, offering flexibility in the field.
What materials can be tested?
It is designed for cemented carbide, stainless steel, and aluminum alloy, among other metals.
