The standard of ultrasonic test the forging of the mould will be ultrasonically tested as per jbt1581-1996 or equivalent standard, details as follows: a. Without bursts, crack, shrinking hole and other defects. B. The defect with size within 2mm can be ignored. C. There should not have compact district. D. Individual defect with diameter of 2~4mm is permitted, and the distance of the neighboring defects should be more than the 10 times of the bigger oneã¢ï¿½ï¿½s. For 100cm2ã¢ï¿½ï¿½ s area, the quantities of the defects with diameter of 2~4mm should not exceed 3. The above-mentioned parameters are for reference only, we can produce various kinds of pipe mold as per customersã¢ï¿½ï¿½ requirements. 8. Package by crate adapted to seaway.
