Ultrasonic Testing

If asked by the customer, pipes are subjected to Ultrasonic testing. An acoustic transmitter probe generates a sound beam which is applied to test piece using oil as Couplant. The Ultrasonic Test Equipment is calibrated using a reference test piece with artificial test which is from the same pipe lot that is to be tested. The tested tubes are considered flawless if they do not cause any indications longer than that produce by the reference test piece. The Ultrasonic Test is conducted as described in ASTM E 213/A-450.
