Ding Testing & Inspection: Industrial Pipeline Non-Destructive Testing (NDT), Safeguarding the Safe Passage of Energy Flow
Industrial pipeline non-destructive testing (NDT) is a critical method that uses various non-destructive techniques to assess the integrity of pipelines, prevent leaks, and avoid failures. Ding Testing & Inspection provides professional NDT services for industrial pipelines to ensure their integrity and safety, preventing potential failures and accidents.
Service Introduction
Pipeline transportation is one of the five major transportation methods, alongside railways, roads, waterways, and air transport. Pipelines are typically categorized into industrial pipelines, public utility pipelines, and long-distance pipelines. Given that a significant portion of China's pipelines have entered the internationally recognized peak maintenance period, and destructive accidents occur from time to time, understanding the main modes of pipeline failure and mastering and enhancing non-destructive testing techniques for pressure pipelines is an effective way to maintain normal production, prevent accidents, and safeguard people's lives and property.

Inspection Items
Non-Destructive Testing
|
Radiographic Testing (RT)
This technique utilizes the penetrating properties of radiation to inspect the internal and surface quality of pipelines. Common types of radiographic testing include television inspection for pipeline components, visual inspection for surface cracks and seams, and photographic inspection for pressure welds and pipeline installation.
|
|
|
|
Ultrasonic Testing (UT)
This technology uses ultrasonic waves, which reflect and refract when encountering interfaces. Instruments receive and analyze these signals to identify internal defects in pipelines, primarily used for inspecting internal welds.
|
|
Magnetic Particle Testing (MT)
By magnetizing the pipeline, a leakage magnetic field is created at the surface and near-surface defects, which attracts magnetic particles to reveal the shape, size, location, and severity of discontinuities, indicating the presence of defects. This method is typically used for surface and near-surface inspections of pipeline welds, requiring both transverse and longitudinal magnetization to ensure quality.
|
|
|
|
Penetrant Testing (PT)
This involves applying a coloring or fluorescent penetrant liquid evenly to the surface of the pipeline. The liquid seeps into surface-opening defects through capillary action. After removing the excess penetrant, a developer is applied to draw out the penetrant, revealing surface defects and identifying opening defects.
