Carbon steel flange, the body is made of carbon steel flange or end flanged fittings. Contains carbon steel material of flange, known as the carbon steel flanges.
Flat welding flange and pipe connection and butt welding is the welding way. Overall, flat welding flange joints is processing a slightly larger than the pipe diameter of a concave, pipe welded inside. Butt welding flange is the interface the pipe diameter and wall thickness as the pipe to be welded, meet two pipe welding. Butt welding performance is better, less corrosion. The flat welding flange welding with one-side welding does not need to welded pipe and flange connection inside the mouth, the welding of butt welding flange installation requires flange welding by both sides. So flat welding flange is generally used in low and medium pressure piping, used for medium and high pressure pipe butt welding flanges, butt welding of flange is usually at least PN2.5 MPa, the butt welding is to reduce the stress concentration, generally the butt welding of flange with flange neck flange is also called the nipple.
