Seamless pipe ultrasonic inspection system

The 32-channel FLAW HUNTER SLP 9503, Seamless Pipe Ultrasonic Inspection System, respects all international standards, such as API 5L and 5CT, as well as the demands of manufacturers and inspectors of such types of pipes. The reference defects of the international standards for seamless pipes can be found using the ultrasonic inspection system for seamless pipes. A 1.6 mm diameter hole, an FBH hole Ø6 mm with a depth of half the wall’s thickness, and four longitudinal and transverse grooves of types N12.5, N10, and N5 on the pipe’s inner and outer surfaces belong to the defect kinds.1

probe holders in Seamless pipe Ultrasonic Inspection System

In this technique, the probe holders are positioned on a carrier and are moved over the device’s initial canvas by the encoder at a distance of approximately 13 meters. The probes use an accuracy step to scan the entire tube’s body while the tube is rotating.2

...is updating

On the other hand, the water column technique is used to conduct the test because of its high sensitivity and the poor surface quality of seamless pipes as a result of heat treatment and hot rolling.8

Upgrade the seamless pipe ultrasonic inspection system

This system can be expanded to two separate heads (each capable of evaluating six meters of pipe) and increase the number of channels and probes to 64 in order to test pipes more quickly (one branch every minute).9

The location of the probes inside the holders

Eight channels are used to measure thickness.3

Twelve channels, arranged in two groups of six, are used to discover longitudinal defects both internal and the outside.4

The channels transmit sound waves within the pipe wall in both clockwise and counterclockwise directions.5

Twelve channels, arranged in two groups of six, are used to detect internal and external transverse flaws.6

The channels face one another, project sound waves in opposite directions, and run parallel to the pipe’s longitudinal axis inside the pipe wall.7
