Carbon Steel Flange, Forged stainless steel Flange,Weld Neck Flange, Slip on flange , Plate flange , Blind Flange
Production process is divided into forging, casting, cutting, these three.
Casting flange and forged flange
Casting out of the flange, rough shape size, processing capacity is small, low cost, but there are casting defects (pores. Cracks. Inclusions); casting internal organization streamlined poor (if the cutting parts, streamlined)
Forging flange is generally less than the casting flange carbon is not easy to rust, forging streamlined, the organization is more compact, mechanical performance is better than casting flange;
Forging process improper also appear grain large or uneven, hardening crack phenomenon, forging costs higher than the casting flange.
Forging is able to withstand higher shear and tensile forces than castings.
Casting the advantage is that you can come up with more complex shape, the cost is relatively low;
Forging the advantages of internal organization is uniform, there is no castings in the pores, inclusions and other harmful defects;
Blind Flange sealing surface in the form of more types, FF, RF, MF, TG, RJ. It is the middle of the flange without holes, used to plug the pipe mouth. Materials are carbon steel, stainless steel, alloy steel.
