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.
