In this paper,a data acquisition software system with high acquisition rate and accuracy is designed for steel pipe inspection.The speed of data acquisition and processing is improved by raising the thread priority of the data acquisition module and by using DMA and double-buffering transmission mode.The accuracy of flaw signal processing is improved by adopting an efficient pulse width detection module.The new system of magnetic flux leakage（MFL） inspection by using this data acquisition software has gained positive feedbacks after being put into use in several oil and metallurgical corporations.
