Product Details

Portable Indentation Stress Tester PMT-1000 for On-Site Petrochemical and Nuclear Equipment

Minor damage, high-accuracy stress assessment for in-service pressure vessels, pipelines, and structural steel.

The PMT-1000 is a portable, nondestructive indentation stress tester designed for on-site measurement of residual and applied stress in industrial equipment. It is particularly suited for aging property change assessment in nuclear and petrochemical plants, and for periodic stress tracking on installed steel structures.

By applying a controlled indentation, the device captures stress distribution data without disassembling critical components, leaving only micron-scale, easily removable marks.

Key Features

On-site stress measurement – outputs stress values in real time for immediate overload judgment.
Handheld & portable – ideal for rapid safety assessment of bridges and pressure vessels.
Minor damage – leaves only micron-scale indentations (depth 60–120 µm) that can be removed by brushing or light sanding.
Versatile materials – works on cemented carbide, stainless steel, and aluminum alloy.
Broad application – suitable for petrochemical, energy, wind power, aerospace, pharmaceutical, and new materials industries.
Data acquisition – 100 Hz sampling rate ensures precise stress variation capture.
