Ding Testing & Inspection: Ship Non-Destructive Testing (NDT), Safeguarding the Safe Passages of Maritime Navigation
Ship Non-Destructive Testing (NDT) is a non-invasive inspection technology used to assess the structural integrity and safety of ships to prevent potential structural failures and maritime accidents. Ding Testing & Inspection provides professional NDT services for ships, ensuring the integrity and safety of ship structures and safeguarding safe and compliant maritime navigation.
Service Introduction
With the continuous advancement of modern technology, China's maritime trade routes and maritime defense have also developed, leading to higher demands for related technologies in the shipbuilding industry. This has resulted in the wider application of non-destructive testing (NDT) technology in ship welding inspection in China. This technology not only enables the inspection of complex ship hull welding but also does not cause damage to the welded parts or the hull, saving manufacturing costs.
Inspection ScopeShip Structure Non-Destructive Testing
Ship Piping Systems
Drainage pipes, ventilation pipes, electrical conduits, fuel oil pipes, lubricating oil pipes, seawater pipes, freshwater pipes, fire-fighting pipes, bilge water pipes, compressed air pipes, hydraulic pipes, ballast water pipes, exhaust pipes, valves, etc.

Other Equipment
Fuel pumps, lubricating oil pumps, cooling water pumps, heaters, filters, coolers, ship power stations, boilers, compressors, pumps for various ship systems, lifting machinery, maintenance machine tools, etc.
With modern NDT technology, not only can existing defects in ships be detected, but these defects can also be specifically evaluated, including defect shape, size, distribution, location, type of defect, etc. Additionally, specific data such as the physical properties of welding materials, temperature, stress, endurance, and thickness can be measured.
Non-Destructive Testing Methods
| Radiographic Testing (RT) | The main principle of radiographic testing is to use rays emitted from a radiation source to penetrate the weld and expose the film. The image of the weld defect will then be displayed on the film. |
| Ultrasonic Testing (UT) | Compared to radiographic testing, ultrasonic testing has certain advantages, such as high sensitivity, low cost, short cycle, high efficiency, and most importantly, no harm to the human body. However, ultrasonic testing also has some drawbacks, such as less intuitive display of defects and higher technical and experience requirements for inspectors. |
| Penetrant Testing (PT) | The main principle of penetrant testing is to apply penetrant liquid containing pigments or fluorescent powders to the surface of the weld to be inspected, allowing it to penetrate into surface-opening defects. After cleaning off the excess penetrant liquid and drying, a developer is applied to observe the defect traces. |
| Magnetic Particle Testing (MT) | Both magnetic particle testing and penetrant testing are methods for inspecting surface quality of welds and are mainly used to check surface and near-surface defects. |
