ASTM A633 Gr.E steel plates are applied in large marine structures

ASTM A633 Gr.E steel plates are widely applied in marine oil and gas drilling and production platform and other large marine structures. That is decided by both the working condition characteristics and A633 Gr.E steel performance.

Offshore oil and gas drilling platforms and other large marine structures work under the wind, waves and currents, sea water corrosion and even cold work environment. Especially in the deep sea area, offshore oil and gas drilling platforms are also affected by internal waves generated by sea density stratification and water flow and structure interaction potential flow dynamics, so they usually have special structures, and have higher requirement for steel material than shipbuilding steel.

Offshore oil and gas drilling platforms and other large marine structures are mainly built with steel materials such as ASTM A633 Gr.E steel plates. The steel they use most are welded high strength structure steel and and high strength low alloy corrosion resistant welding steel. ASTM A633 Gr.E steel plates not only comply with various classification rules, but also have good lamellar tearing performance and welding joint COD performance. ASTM A633 Gr.E steel plates can well meet the requirements of offshore oil and gas drilling platforms and other large marine structures for steel materials.
