There should be no visible defects such as cracks, folds and heavy skin on the surface of the product. Local defects on the surface can be removed by grinding. The cleaning depth should not exceed its dimensional tolerances, and the minimum allowable size should be guaranteed. The ratio of cleaning depth to width should be no more than 1:6 on both end faces, and no more than 1:10 on the inner and outer sides. The outer side of the grinding should be along the axial direction.
Surface finish: clean, dust-free, better acid-resistant service life.
Testing: mechanical properties, chemical composition testing, ultrasonic testing.
