Innovative Nondestructive Testing Methods in Welded Pipes by MT Stainless Steel
MT Stainless Steel, a trailblazer in the manufacturing sector, is increasingly focusing on quality assurance through nondestructive testing within the welded pipe industry. This advanced approach ensures the highest level of precision and safety in the process of manufacturing and making use of welded pipes.
Nondestructive testing methods, such as ultrasonic testing, off-line magnetic flux leakage testing, and eddy current testing, have been a breakthrough in maintaining weld quality. The ultrasonic flaw detection, in particular, has significantly impacted the industry owing to its high defect detection sensitivity, easy judgment, and simple flaw detection graphics.
MT Stainless Steel has seamlessly incorporated these methods into their quality assurance processes. The utilization of the direct contact method, most commonly used in the actual flaw detection due to its convenience in operation, has notably enhanced the company’s productivity.
MT Stainless Steel also employs the liquid immersion method, where the ultrasonic probe and the workpiece are immersed in a liquid, using it as a coupling agent, typically oil or water. Though more suitable for specimens with a rough surface, this method has proved to be highly effective due to its stable coupling and repeatability of detection results. It is further beneficial as it minimizes probe wear and facilitates automatic flaw detection.
The offline flaw detection of welds, a complex process where the welded pipe is carefully rotated manually to a certain point of the weld on the idler, has been successfully executed at MT Stainless Steel. The flaw detection trolley runs sequentially with each group of probes falling on the welded pipe ensuring a thorough inspection.
MT Stainless Steel's commitment to quality and precision, backed by advanced nondestructive testing methods, has bolstered its standing in the industry. The company continues to deliver high-grade welded pipes and contribute to the industry with its innovative approaches to flaw detection and overall quality assurance.
