Subsea pipelines are pipelines that continuously transport large amounts of oil (gas) through sealed pipelines on the seabed. They are the main component of offshore oil (gas) field development and production systems, and are currently the fastest, safest, and most economically reliable mode of offshore oil and gas transportation.

In terms of bearing dock structures, pipe piles are the main bearing materials for dock platforms, piers, berths, and other structures, with high strength and stiffness, which can meet the needs of dock structure bearing.

The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates, and adopts rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, galvanizing, etc.

In terms of coke transportation, spiral welded pipes have high strength and wear resistance, which can meet the needs of coke transportation. In terms of gas transportation, spiral welded pipes have good corrosion resistance and oxidation resistance, which can meet the needs of gas transportation.
