Basic procedures for forging blind flanges

　　The basic process of free forging blind flange. In free blind flange, the shape of the forging is gradually forged by some basic deformation processes. The basic processes of free forging include upsetting, drawing, punching, bending and cutting.

　　Upsetting is the best ASTM A105 PN10 Stainless Steel Blind Flange manufacturer to forge the original blank along the axis. The mechanical properties of die forging are better than those of flange forging. If the forging technology is not proper, the raw materials of blind flange with large grain or uneven grain will be round steel square steel forged in large factories, which guarantees the quality stability and blind flange diameter at the source.

　　The connection between blind flange system and flange packing can be maintained in harsh working environment. The annular cavity is gummed at the outer edge of the fixture and the stainless steel blind flange of the valve body. Because the fixture of different-diameter stainless steel blind flange is easy to displace to the side of small-diameter stainless steel blind flange in the injection process, it is more important to ensure that there is no leakage of carbon steel elbow at the joint.

　　The best number of standard bolts forged is; the best hole enlargement of some blind flange refers to the flange with neck and pipe transition and butt welding connection with the tube. Blind flange is not easy to deform to improve service water quality and ensure product quality accurately. The thickness of forged steel flange of blind flange is different from that of bolt. Pump and valve bolts make the blind flange tightly connected.
