ISO 11484 Eddy Current Testing of Steel Tubes
The ISO 11484 standard specifies the eddy current testing (ECT) procedure for detecting surface and subsurface defects in steel tubes. This service is critical for industries reliant on structural integrity, such as oil and gas, aerospace, and construction. ECT allows for the non-destructive evaluation of materials without compromising their physical properties or dimensions.
During this process, a probe or coil generates an alternating magnetic field that induces eddy currents within conductive materials. The interaction between these eddy currents and the external magnetic field produces detectable changes in signal strength. These variations indicate the presence of defects such as cracks, porosity, or other anomalies.
The primary advantage of ECT is its ability to assess both internal and external surfaces simultaneously. This capability makes it particularly useful for inspecting complex shapes or structures where access might be challenging. The test can also provide real-time data on the condition of materials under inspection, enabling immediate corrective actions if necessary.
The standard covers various aspects including probe selection, testing frequency, and acceptance criteria. It ensures that all tests are conducted consistently across different facilities, enhancing reliability and comparability between results obtained from different laboratories.
