With a capacity of 150,000 tons per year, CSI's pipe mill products include outside diameters ranging from 4-1/2" to 16", wall thicknesses ranging from .156" to .500", with lengths available up to 63 feet with no mid-weld. Process coating is available through local coating applicators.

  We produce ERW pipe by rollforming hot rolled coil into a pipe shape, welding the edges together with a high frequency welder, annealing the weld and cutting the finished product to length on a continuous line. The pipe may then undergo additional testing or finishing operations, such as hydrotesting and end beveling.
