UNITED CASING, INC. (UCI) was originally established in 1974 as an OCTG trading company. In 1986 we enhanced our capabilities by establishing an API-approved threading facility in Corpus Christi, Texas. A second facility was added in Germany in 1994 (later sold to a pipe manufacturer), and a third was added in Houston, Texas in late 1999. In April 2010 we acquired an additional facility in Midland, Texas. UCI has a worldwide customer base  (see Customer Reference list) and maintains offices in Switzerland and USA. United Casing’s prime focus is on OCTG (casing and tubing), but we also provide line pipe and specialty tubulars for refineries and high tech applications.
