Summary

Borusan Berg Pipe is the U.S. subsidiary of Turkish producer Borusan Boru. Per trade coverage it makes large-diameter steel pipe at facilities in Mobile, Alabama and Panama City, Florida (Tube Tradefair; Pipeline Journal). The only project tie verified here is Eiger Express: a $567M sales agreement with Eiger Supply LLC for about 107 cm (42-inch) pipe, deliveries scheduled throughout 2026. Eiger Express is a roughly 450-mile, 42-inch, up to 2.5 Bcf/d line from the Permian to Katy, Texas, owned through the Matterhorn JV (WhiteWater, MPLX, Enbridge; 70%) with ONEOK and MPLX 15% each; WhiteWater builds and operates it (Yahoo Finance). One source describes the pipe as covering about 725 km, consistent with that length.

What It Is / How It Works

Large-diameter welded line pipe is bought by the pipeline owner (or its builder) well ahead of construction. A mill order is therefore one of the earliest observable signals that a project is moving from permit to build.

Notable Developments

  • 2025-08-27: $567M agreement for Eiger Express pipe disclosed (Turkey KAP filing per the coverage). (Pipeline Journal)
  • Steel Market Update’s sidebar (2026-08) lists a headline that Commerce raised anti-dumping duties on large-diameter welded pipe from Turkey; the underlying article was not read, so applicability to Borusan’s U.S.-made pipe is unverified.
