Product Details

Pipeline Weld Residual Stress Tester for Girth Weld Axial-Hoop Separation

Model: PMA-1010 | Type: Portable Nondestructive Indentation Tester

Product Summary

Model PMA-1010 is a portable nondestructive indentation tester specifically designed for measuring residual stress in pipeline girth welds. It uniquely distinguishes axial from hoop residual stress, facilitating precise stress analysis and helping to locate critical high-stress areas.

Key Features

Axial & Hoop Stress Separation

Distinguishes axial residual stress from hoop residual stress in girth welds.

Circumferential Scanning

Rapidly scans the entire circumference of a girth weld to locate high-stress arc segments.

Weld Pass Mapping

Maps residual stress distribution across root, fill, and cap passes of pipeline welds.

Yield Ratio Warning

Outputs residual stress to yield ratio to warn of weld plastic collapse risk.

Non-Interference Indentation

1mm indentations do not affect PIG passage.

FAQ

Q1: Can this tester separate axial and hoop stresses?

Yes, it can distinguish axial residual stress from hoop residual stress in girth welds.

Q2: How does it locate high-stress areas?

It rapidly scans the entire circumference of a girth weld to locate high-stress arc segments.

Q3: What is the indentation size?

Each indentation is 1mm, which does not affect the passage of pipeline inspection gauges.

Q4: Can it map stress across weld passes?

Yes, it can map residual stress distribution across root, fill, and cap passes.

Q5: What power supply does it need?

It can operate on 220V wired or 24V wireless power.

Q6: What materials can be tested?

Cemented carbide, stainless steel, and aluminum alloy are compatible.
