Forged Marine Flange

Flange forging is one of the marine flange production process. Different from the common casting flange, the general raw material of the forging flange is the billet, the billet will be cut after continuous hammering, in order to eliminate the segregation in the ingot, loose. Forging flange is one of the best mechanical properties of marine flanges.

Stainless steel SS316 weld neck flanges and slip on flanges

Forging marine flange internal structure uniform, no pores, inclusions and other harmful defects. Low carbon content is not easy to rust, dense structure, good appearance, than the casting flange can withstand higher tensile force and shear force, so the forging cost is slightly higher. Forging process is generally select high-quality billet blanking, heating, forming, cooling after forging. The forging process includes free forging, mold forging and foetal membrane forging. In production, according to the size of the forging quality, the number of production batches to choose different forging methods.

BS 4504 ASTM A105 raised face slip onf flanges and blind flanges

Forged marine flanges are mainly made of carbon steel, alloy steel and stainless steel. The main standards are national standard, American standard, German standard, Japanese standard and so on. The main anti-corrosive treatments are oiled and galvanized. Forged flanges have good pressure and temperature resistance, and are generally suitable for high pressure and high temperature working environment in ship manufacturing and operation.
