International Pipe was founded in 1978 by Alfred H. Karchmer. In 1985, his son, Donald, joined the business after graduating from college. Together, they spent the next several decades growing it into one of the nation's leading steel pipe distributors. Today, as a third-generation family-owned and -operated business, we take our reputation very seriously and always operate with the highest level of integrity. It’s our mission to achieve excellence in customer satisfaction, each and every day!

At International Pipe’s headquarters in Oklahoma City, we operate a 35-acre, full-service facility, which houses our corporate offices, processing center, and state-of-the-art fabrication/welding shop. Our experienced office staff and yard crew always work hard to ensure accurate order processing and prompt customer service.

We supply products to dealers, end users, and contractors for a wide array of uses, including, but not limited to, general construction, utilities, boring/excavation, infrastructure, and oil & gas. With tens of thousands of tons in stock, you can believe that we have the steel pipe you need for your next project! For 45 years, we’ve remained your one-stop source for new, used, and surplus steel pipe, ranging in diameter from 1/4" to 120", in numerous wall thicknesses, and with various finishes.

We’re extremely proud and excited about growth, especially in 2024! In addition to Bison Pipe in Jerome, ID and Bigfoot Pipe & Piling in Puyallup, WA we have recently acquired assets and formed Big Bear Pipe & Steel in Hesperia, CA, to expand our reach, enhance our capabilities, and better accommodate our customers' needs.
