| High-speed, precision inspection machines for detection, evaluation and documentation of flaws in large, thick-walled tubulars |  |
PRODUCT DESCRIPTION |
| Introducing the AS-280 Series
AS-280 Series machines are intended for high-speed, high-sensitivity and repeatable ultrasonic inspection of large, thick-walled tubulars. Employing unique dual-servo drive rolls and servo-driven inspection robot. Inner and outer wall surface cracks and internal flaws from the near-surface to inner wall are detected and evaluated directly from the operator control console. |
| Suitable test parts
Extruded tubulars with lengths to 13000mm (45ft), O.D. from 150 to1200mm (6" to 48") and wall thickness to 250mm (10"). Ground surface finish ensures sensitive and repeatable inspections. |
| Inspection technique
Contact inspection with water coupling, using transducer bubblers and hardened, replaceable wear shoes. |
| Flaw detection
Internal flaws - from 0.8mm (No.2) diameter flat-bottomed hole (FBH) at 2.5mm (0.100") to 250mm (10") depth. Other detection sensitivities per customer request. Surface cracks - depths from 2 percent wall thickness, inner and outer surfaces. |
| Inspection (feed) rates
Surface inspection speeds to 600mm/sec (24in/sec). Axial inspection index to 25mm (1") per revolution of the tube, dependent on beam overlap requirements and tube diameter. |
| Surface coverage
100 percent to within 12mm (0.5in) of the tube ends. |
| Inspection robot (Z-axis) and operator cab (Xa-axis)
Rugged, beam-mounted inspection robot, including inspection head with three multi-channel transducer manipulators. Beam height is pre-positioned according to inspected tube diameter. Inspection robot is fixed to the track-mounted operator cab which tracks the tube axially over its whole length. The air-conditioned cab houses the ultrasonic electronics and system control console. All motion axes are servodrive, including digital motion control for precise positioning and display. |
