Deng), third party's injury and the influence (earthquake, jump in temperature, strong water flow fluctuation etc.) of temperature, environment.Except causing weight
Outside big economic loss, the breakage of oil and gas pipeline has also indicated main environmental hazard and the potential threat to life, because
This must be prevented by effective pipeline integrity management system.Rational Maintenance of these measures including pipeline and cleaning are kept away
Exempt from line clogging, and inner and outer pipes road state is evaluated by periodic Non-Destructive Testing, had found that it is likely that before causing puzzlement the defects of
And endanger to keep the normal operation of pipeline.
Pipeline detection instrument (common name detector) can be cleared up but also detected, and key is played in pipeline infrastructure management
Effect.In terms of current pipe detection, pigging and detection are to be responsible for respectively by two kinds of entirely different instruments：Wiper and pipeline
Internal detector.
