All pipes are continuously measured for out of roundness at final visual and dimensional inspection station.The inspection is performed by laser sensors and PLC based automation. The pipe number to be tested is recorded by operator. The inspection results are entered by HMI Screen. System will calculate the out of roundness and compare with the limit given by related specification.Laser Head is rotated to measure the diameter at any point of pipe. Pipe is turned to inspect each end in the same station.
