First, the external coating of the measuring instrument pipe inspection specifications
1, on the type of coating indefinite
2, for gas smothered pipeline destruction point with a strong ranking capability and accuracy, positioning pipe outer cover destruction point accuracy ± (1.0m) or less. Able to the efficiency of pipeline coatings evaluated preferred.
3, the instrument involves light, the system showed a direct, simple and efficient operational requirements.
Second, the pipe inspection deterioration 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 blends of gas pipeline diameter size measurements;
3, have sufficient wall thickness detection accuracy, the reliability of at least 2%, one-time detection of length greater than 200 meters;
4, the instrument system specifications for visual display of the test results can be obtained directly corrosion depth, size and general shape;
5, the detection equipment are little, mild weight, easy on-site flexible application.
