12 Claims

1. A method for monitoring for maintenance and repair of gas pipelines made of metal for detection of internal corrosion that can result in leaks causing catastrophic failures, the method comprising: providing corrosion sensors for detection of internal corrosion; providing a wireless sensor network, comprising several wireless transceivers, that collect the sensor data from multiple sites and provides maintenance alerts for repair of the pipelines; establishing the wireless sensor network inside the pipelines using a method for delivery of the sensors to the site; activating the sensors to make measurements periodically or continuously; extracting the corrosion sensor data from the sensors using a the wireless network to access points in the pipelines and analyzing sensor data using a recommendation engine.
