In the pipeline industry, real-time monitoring is becoming a big business. Systems monitor pipeline integrity, temperature, vibration, leaks, personnel and equipment, as well as watch for intruders. These systems use a variety of communication methods, including fiber optic cable strung along the pipeline, cellular, satellite, wireless and Ethernet.
Polyethylene (PE) is the primary material used for gas pipe applications. Because of its flexibility, ease of joining and long-term durability, along with lower installed cost and lack of corrosion, gas companies want to install PE pipe instead of steel pipe in larger diameters and higher pressures. As a result, rapid crack propagation (RCP) is becoming a more important property of PE materials.
