Interstate pipelines deliver an important energy source safely, efficiently and reliably 24 hours a day, 365 days a year.
Transmission pipes can measure anywhere from 6 to 48 inches in diameter. The actual pipeline consists of a strong carbon steel material, engineered to meet vigorous standards.
The pipe is also covered with a specialized coating to ensure it does not corrode once placed in the ground. The purpose of the coating is to protect the pipe from moisture, which can cause corrosion and rusting.
