Factory spark testing is a critical non-destructive inspection procedure carried out by Suote Machinery to ensure product quality and safety. It is mainly used to detect tiny cracks, pinholes, damaged coatings and insulation defects on the surface of metal equipment such as storage tanks and pressure vessels. During production, professional spark testing equipment is used to apply high-frequency voltage to the workpiece surface. If defects exist, spark discharge will occur, allowing inspectors to accurately locate and mark problems in a timely manner. This testing ensures that equipment surfaces are intact, corrosion-resistant and insulating, meeting strict standards in pharmaceutical, food and chemical industries. Strict factory spark testing guarantees stable performance, extended service life and reliable operation of each product delivered by our factory.
