IMPROVED STRENGTH AND TOUGHNESS FOR OFFSHORE STEEL
- Using high-strength steel structural Sections and ultra-high-strength offshore steel can reduce the self-weight of offshore platform structures and increase the platform’s variable load and self-sustainability, as well as the ratio of total displacement to the structure’s self-weight.
- Peakkong Special Steel Factory produces high-strength steel structural profiles for offshore structures, complying with EN 10225 and API standards for all steel grades. Starting from basic steel grades such as S355G2+N to S355G7, G8, G9, G10 up to S460G2+M/QT.
- Peakkong Special Steel's offshore high strength structural steel sections are mainly dedicated to the challenging conditions and engineering complexity of offshore construction projects, which means that offshore high strength steel structural sections are the only ones that can meet the rigorous and continuous integrity of these structures,Require.
- Offshore structures built specifically to drill for oil and gas deposits deep under the seabed are constantly exposed to the corrosive effects of seawater, strong currents, strong tides and high winds.
- The specific technical specifications of Peakkong Special Steel high-strength steel structural Sections for offshore use are crucial to ensure that they can withstand the continuous pressure from the natural elements, thereby providing a longer working life, greater safety and reduced risk of failure, in a certain In some cases, the risk of failure can be catastrophic, if not fatal.
High-strength steel structural profiles for offshore use mainly include:
- H-shaped steel
- I-beam
- channel steel
- square tube
- steel pipe
- flat tube
- T-shaped steel and other profiles
