The offshore platform steel plays an important supporting role in offshore platform building. Because the offshore platform is immersed in seawater for a long time, it needs to withstand various severe sea conditions such as storms, waves, glaciers and so on. Therefore, the offshore platform steel requires not only high strength, but also good corrosion resistance, low temperature toughness and lamellar tearing resistance.
At present, offshore platform steel in the world is divided into mild steel, medium high strength steel and high strength steel from the strength. Meanwhile, considering the stability and reliability of offshore platform components, different strength steel should meet different yield ratio. In addition, the thickness requirements of the steel plate are different due to the different parts used on the offshore platform.
In recent 10 years, domestic offshore platform steel has been widely used in China's offshore oil engineering, and offshore platform steel has gradually developed towards high strength direction.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
