As special equipment, long-distance oil and gas pipelines are widely used in petroleum, petrochemical and chemical industries. However, due to the tight construction schedule, heavy task and large amount of work of pipelines, the geographical environment and climatic environment of field welding are complicated, which are demanding on reliable welding process. Conventional NDT methods may have defects inevitably.

SIUI recommend the PAUT inspection system consists of six parts, including a PA ultrasonic flaw detector, a PA/TOFD probe wedge, a crawler and analysis software, a water irrigation device, and a calibration and simulation test block. By using special software for the PA ultrasonic flaw detector, drafting of testing process, probe calibration, and data acquisition and analysis can be easily completed. The configured chain crawler adopts the chain plus magnetic guide design, which achieve high-precision probe walking trace and stable movement, and reduce repeated scanning. The weld inspection will be achieved quickly by using the whole system. The advantages of the solution as below:

• PA&TOFD testing: Improve testing speed &defect detection rate significantly.
• Color image: Intuitive test result, without environmental pollution.
• Covering effective weld area: Enables rapid detection of flaws.
• TOFD: Accurate measurement of defect height.
