Dual-Phase Steel Outfittings Fabrication For Chemical Cargo Ship

Recently, Openex successfully completed the delivery of chemical ship outfitting parts for Hudong Shipyard. The main material of the metal parts is 2205 Dual-Phase Steel. There are more than 2400 pieces of about 70 kinds of specifications. The fabrication technology of this batch of steel outfittings is complex, involving leveling, oil grinding, laser cutting, edge milling, press braking, 5 axis waterjet cutting, machining, etc.

Dual-phase steel is commonly used in chemical cargo ships because of its high strength, corrosion resistance, and improved ductility. Chemical cargo can be highly corrosive and can cause damage to the ship's hull and other components. Dual-phase steel's improved resistance to corrosion can help prevent damage and maintain the structural integrity of the ship. In addition, its high strength and improved ductility make it less likely to fracture under stress, which is important for ships that may encounter high stresses and strains during transport. Therefore, dual-phase steel is a preferred material for the construction of chemical cargo ships.

Steel outfittings for a chemical cargo ship typically refer to various metal components(like valves, fittings, and flanges) installed on the vessel that are designed to withstand the harsh conditions of transporting hazardous chemicals. Steel outfittings for ships are fabricated using a variety of processes, depending on the type and complexity of the component. Here we list some common fabrication methods used in steel outfittings:

• Cutting: Steel plates or bars are first cut to size using processes such as shearing, plasma cutting, or laser cutting. This produces the basic shape of the component.
• Forming: The steel is then shaped into the desired form using processes such as rolling, bending, or stamping. This involves the use of specialized machines and tooling.
• Welding: The individual components are then welded together using a variety of welding techniques, such as arc welding, gas welding, or resistance welding. Welding may also be used to attach fasteners, such as nuts and bolts.
• Machining: Machining involves removing material from the workpiece using a cutting tool to produce the required shape, size, and surface finish. Common machining processes includes turning, milling, boring, drilling, grinding, etc.
• Surface treatment: The finished component may be subjected to surface treatment processes, such as sandblasting, priming, or painting. This helps to protect the component from corrosion and other forms of damage.

Fabrication of steel outfittings for ships requires specialized knowledge and skills and is typically carried out by experienced and qualified fabricators who have expertise in shipbuilding and marine engineering.
