DN1200 butterfly valve magnetic particle non-destructive testing
In the field of valve manufacturing, quality has always been the lifeline of enterprises. Recently, our factory conducted strict magnetic particle testing on a batch of flanged butterfly valve with specifications of DN1600 and DN1200 to ensure high-quality valve welding and provide reliable products for customers.
DN1600 and DN1200 large-diameter butterfly valve pneumatic play a crucial role in many industrial fields. These valves are usually used to transport large amounts of fluid media, and their quality directly affects the safe and stable operation of the entire system. To ensure welding quality, we have adopted advanced magnetic particle inspection technology.
（MT）Magnetic particle inspection is a non-destructive testing method that can effectively detect surface and near surface defects in valve welding areas. During the inspection process, the magnetic powder is evenly sprayed onto the surface of the ductile iron butterfly valves, and then the magnetic field is used to gather the magnetic powder at the defect site, forming obvious magnetic marks, thereby accurately determining whether there are cracks, pores, slag inclusions and other defects in the welding area.
Our factory's technical personnel operate strictly in accordance with testing standards and procedures with a high sense of responsibility and professional spirit. They carefully adjust the magnetic field strength and the amount of magnetic powder sprayed to ensure the accuracy and reliability of the test results. Any defects detected shall be promptly recorded and analyzed, and corresponding repair measures shall be taken until the 1200mm butterfly valve fully meets the quality requirements.
Through this rigorous valve magnetic particle inspection test, we not only ensured the welding quality of this batch of large-diameter actuated butterfly valve, but also further improved the product quality and market competitiveness of our factory. We will continue to adhere to the quality control concept of high standards and strict requirements, continuously optimize production processes and testing methods, provide customers with more high-quality valve products, and contribute our own strength to promote the development of the industry.
