Correct Pigs, Procedures for Hydrostatic Testing of New Pipelines

Laying a cross-country pipeline is expensive. Many hours of engineering and planning must meet certain standards and regulations and receive federal government approval before starting construction. It costs approximately $100,000 per diameter-inch-mile to build a pipeline in a reasonable lay area. This number can easily triple in marsh lands, hills, mountains and rocky terrain. In those areas it could cost about $20 million to lay 100 miles (161 km) of 20-inch pipe.
