Production process of blind flange

　　The cast blind flanges are accurate in shape, small in processing and low in cost, but have casting defects (holes, cracks and inclusions), and the internal structure of the castings is poor (if it is a cutting piece, the streamline is worse).

　　The A105 P250gh Carbon Steel Blind Flange is generally less carbon than the casting blind flange, and it is not easy to rust. The forging is streamlined, the structure is compact, and the mechanical property is better than the casting blind flange.

　　Improper forging process also causes large or uneven grains and hardening cracks. The forging cost is higher than that of casting blind flange.

　　Forgings can withstand higher shear and tensile forces than castings.

　　The advantage of casting is that it can produce more complicated appearance and lower cost.

　　The advantage of forging is that the internal structure is homogeneous, and there are no harmful defects such as blowholes and inclusions in the casting.The difference between casting blind flange and forging blind flange is different from the production process, for example, centrifugal flange is a kind of casting flange.
