Product Summary
The Pipeline Weld Residual Stress Tester PMA-1010 is a portable nondestructive indentation tester designed for measuring residual stress in pipeline welds. It supports in-situ measurements on in-service pipelines and is capable of distinguishing axial from hoop stress in girth welds. With a maximum load of 1000 N and an indentation depth of 60-120 μm, it is suitable for macro-scale testing on various materials including cemented carbide, stainless steel, and aluminum alloy. The tester is portable and can be operated by a single person for large-diameter (≥48″) pipeline welds, providing rapid scanning along the circumference to locate high-stress segments. It creates indentations of only 1mm, not affecting the passage of pipeline inspection gauges (PIGs). The device outputs residual stress yield ratio to warn of weld plastic collapse risk and provides data for aging pipelines and repair sleeve installations.
Key Features
1000N Max Load Enables testing on a wide range of materials including steel and alloys, providing valuable data for weld integrity assessment.
Non-destructive Indentation Creates only 1mm indentations, minimizing impact on pipeline integrity and allowing safe in-situ testing on in-service pipelines without affecting PIG passage.
Portable and Single-Operator Lightweight design allows one person to handle large-diameter (≥48″) pipelines, saving time and labor in field operations.
Rapid Circumference Scanning Fast scanning along the entire girth weld circumference to identify high-stress arc segments, efficient for pre-hydrotest verification and post-weld inspection.
Stress Yield Ratio Warning Outputs residual stress yield ratio, helping to predict weld plastic collapse risk and improving safety decision-making.

FAQ
What is the maximum load of the PMA-1010?
The maximum load is 1000 N, allowing testing on a wide range of materials.
Can the tester be used on in-service pipelines?
Yes, it is designed for in-situ measurement on in-service pipelines, and the 1mm indentation does not affect PIG passage.
What materials can be tested?
It can test cemented carbide, stainless steel, aluminum alloy, and other similar materials.
Is the tester portable?
Yes, it is portable and can be operated by a single person for large-diameter (≥48″) pipeline welds.
How does it help in pipeline integrity assessment?
It provides residual stress data that can be used in finite element simulation, failure analysis, life assessment, and safety assessment.
Can it measure axial and hoop stress separately?
Yes, it can distinguish axial residual stress from hoop residual stress in girth welds.
