Ocean pipe

Pipes used in offshore engineering primarily include seabed OCTG pipes, long-distance seabed transport pipes, and internal connection pipes for offshore oil and gas fields (seabed gathering and transportation pipelines, risers, and working connection pipelines). These pipes are required to possess high strength, excellent toughness, and strong resistance to seawater corrosion.
