With the development of offshore drilling platforms from shallow seas to deep seas, the grades of steel used in offshore platforms are correspondingly higher and higher, and the thickness of the steel is also increasing. EQ56, the steel for high-strength hull structures, came into being. EQ56 is steel for offshore platforms, Q refers to high-strength steel, 56 refers to its yield strength of 550N/MM2, and the previous E refers to the E level. The commonly used hull structural steel EQ56 grades are EQ56, EQ56-Z15, EQ56-Z25, EQ56-Z35.
The high-strength hull structural steel EQ56 needs -40℃ impact test. It has high strength, high toughness, fatigue resistance, laminar tear resistance, good weldability and seawater corrosion resistance.
High-strength hull structural steel EQ56 is mainly used for offshore drilling platform racks, drilling platform cantilever beams, offshore windmill installation ships, etc.
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.
Bulb flat steel for shipbuilding
The bulb flat steel is a kind of medium section material which is mainly used in the field of shipbuilding and bridge building, and the shipbuilding bulb flat steel is an auxiliary medium section material for shipbuilding.
