To illustrate the general inspection principle, a typical pulse /echo inspection configuration as illustrated below will be used. Radiographic Testing (RT)Ultrasonic Inspection Operation Scheme of ERW Welded PipeUltrasonic inspection is currently the main non-destructive testing method in the production process of ERW welded pipes. Its main application areas include 1) On-line ultrasonic testing of steel plates. 2) ERW welding, ultrasonic on-line inspection of welds after removal of internal and external burrs. 3) Offline inspection of ERW welds. 4 ERW Steel Pipe Process Performance Inspection StandardsWhat is ERW steel pipe - pipelinedubaiWhat is ERW steel pipe? ERW steel pipe is a straight seam electric resistance welded pipe, abbreviated as ERW pipe, which is a round pipe welded by steel plates. It is used to transport vapor and liquid objects such as oil and n atural gas, and can meet various requirements of high and low pressure. At present, it plays an important role in the world of transportation pipes.
