International Pipe & Supply, LLC. was incorporated in 1978. The company was founded by Alfred H. Karchmer. His son, Don joined him in 1985 and together they grew International Pipe & Supply to become one of the leading steel pipe distributors in the United States. In 2008, International Pipe purchased the assets of KDC Pipe in Rialto, CA and its office in Phoenix, AZ. In May 2011, International Pipe & Supply formed Bison Pipe & Supply, formerly Liberty Pipe in Jerome, Idaho. With a great team led by Darren Sparks already in place, Bison Pipe & Supply better serves our customers in the Northwest region of the United States.  With more than seventy-five years of experience in the pipe and tube industry and more than 50 acres of steel pipe, we are one of the leading new and used steel pipe distributors in the United States. International Pipe has built its business with solid core values and ethics. International Pipe will continue striving for excellence and customer satisfaction in the steel pipe distribution industry.
