X-ray Inspection I: The weld of the pipe is 100% checked by X-ray industrial TV system. The image handling system is also equipped to ensure the inspection sensitivity.
j. Expansion: The pipes are subject to full-length expansion to increase the precision of the pipe dimensions and improve the internal stress distribution.
k. Hydraulic Testing: Each pipe is subject to hydro test to ensure that a specified testing pressure according to appropriate standard is met. The functions for automatic recording and storing are equipped with the machine.
l. Pipe Ends Beveling: All pipes qualified from previous testing are subject to pipe end processing to get the required bevel dimension.
m. Ultrasonic Testing II:After expansion & hydro test, each pipe is tested by ultrasonic tester again for any possible defects occurred during the expanding and hydraulic testing process.
n. X-ray Inspection II:
Each pipe after expansion and hydro test is subject to X-ray industrial TV inspection and pipe-end weld filming.
o. The beveling area of the pipes is magnetic particle inspected for any defects.
p.Coating: The qualified pipes are coated for anti-corrosion as per the requirements of customers.
Besides the inspecting items mentioned above, the destructive inspection and other inspection on the plate and pipe such as raw material incoming sample inspection and plate 100% visual inspection according to API standard and other related standards and other special requirements from the customers are also performed. See attachment for the major process chart.
