摘要

Although tube producers almost universally accept that using some form of nondestructive testing (NDT) is a requirement in tube production, many place too much emphasis on cost when purchasing test equipment.Any savings realized in the purchase price can quickly evaporate if an inappropriate or inadequate system is put into service. Rather than basing a purchasing decision on price, tube producers should consider how the equipment finds defects and how the test results will be used.Tube producers can choose from two main types of NDT equipment-eddy current and ultrasonic-each of which has capabilities and limitations. Tube producers should thoroughly investigate both types before selecting a system. Making an uninformed choice can cut into profits because of missed defects or decreased yield. A practical approach requires investing in results-not hardware.
