First, the external coating of the computing instrument pipe inspection
prerequisites
1, on the type of coating indefinite
2, for gas smothered pipeline damage point with a strong setting capability and accuracy, positioning pipe outer cover damage point accuracy ± (1.0m) or less. Able to the padding of pipeline coatings evaluated preferred.
3, the guitar calls for light, the program showed a direct, simple and efficient operational requirements.
Second, the pipe inspection corrosion detector requirements
1, using a variety of ways (including excavation and no excavation) detection of buried pipes, pipe outer wall can detect corrosion wall loss, circumferential cracks and depth of more than 70% of the longitudinal cracks and external impact damage;
2, suitable for all ones of gas pipeline diameter size measurements;
3, have sufficient wall thickness diagnosis accuracy, the correctness of at least 2%, one-time detection of length greater than 200 meters;
4, the guitar system prerequisites for visual display of the test results can be obtained directly corrosion depth, size and general shape;
5, the detection products are smaller, mild weight, easy on-site flexible application.
