Product Description
Blind flange is also called blind flange, the proper name is called flange cover. It is a flange without hole in the middle for sealing the pipe plug. Sealing surface types are more, there are plane, convex surface, concave and convex surface, tenon groove surface, ring joint surface.
Production technology is mainly divided into forging, casting, cutting, these three.
Casting flange and forging flange
Casting flange, blank shape and size accurate, small amount of processing, low cost, but casting defects (porosity. Crack (inclusion); Poor streamline of casting internal structure (even worse if it is a cutting piece);
Forging flanges generally contain less carbon than casting flanges and are not easy to rust. Forging flanges have better streamlined shape, compact structure and better mechanical properties than casting flanges.
Improper forging process will also appear large grain or uneven, hardening crack phenomenon, forging cost is higher than casting flange.
Forgings can withstand higher shear and tensile forces than castings.
The advantage of casting is that it can make more complicated shape and the cost is lower.
The advantage of forgings is that the inner structure is uniform and there is no such harmful defects as porosity and inclusion in the casting.
From the production process to distinguish the difference between casting flange and forging flange, such as centrifugal flange is a kind of casting flange.
Centrifugal flange belongs to the production of precision casting flange, this kind of casting is much finer than ordinary sand casting, the quality is improved a lot, it is not easy to appear loose structure, pores, trachoma and other problems.
