As we all know the oil well casing pipe plays an important role in the oil industry, in order to ensure the quality of the casing pipe,we have to a series test before the protects leave the factory.But do you know what the inspections we have to do?
Automatic ultrasonic and electromagnetic nondestructive inspection is performed to detect pipe outside and inside flows. Inspection of steel casing pipe ends before threading and couplings after treading is realized by magnetic-fluoroscopic flaw detection. Rolling using a press piercing mill and continuous mill equipped with a fixed mandrel allows strict measurement tolerances to be obtained and ensures a lack of pipe body and surface flows. Wall thickness is inspected throughout the pipe length by the ultrasonic unit.
Oil field casing Pipes are heat-treated in a computerized walking beam furnace. Steel grades and heat treatment regimes applied allow high-strength pipe to be obtained. What I said above is a part of the inspections.After you know the process of the inspection ,I think you have a deeper understand of the casing pipe ,and I will make sure the quality of the products manufactured by our company.
