Marine Construction Foundation Pipe (JCOE LSAW Welded Steel Pipe)
Product Profile
This series of large-diameter welded steel pipes are suitable for long-distance delivery of crude oil, natural gas and coal water slurry on land and offshore waters. Besides fluid transportation, they can act as load-bearing structural pipes for offshore operation platforms, power plants, petrochemical projects, municipal construction and dock foundation projects.
We are a professional manufacturer specializing in JCOE longitudinal submerged arc welded pipes, equipped with complete forming production lines and matched anti-corrosion coating processing workshops.
