carbon steel pipe elbow
carbon steel pipe elbow Carbon steel elbow is a metal pipe fittings that change the direction of the pipeline on the carbon steel pipe path. The connection method has wire buckle and welding. According to the angle, there are 45° and 90°180° three of the most commonly used, in addition to the engineering needs also include 60° and other abnormal angle elbow. Elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The way to connect with the pipe is: direct welding (the most commonly used way) flange connection, hot-melt connection, fused connection, threaded connection and socket connection, etc. According to the production process can be divided into: welding elbow, stamping elbow, push elbow, casting elbow and so on. Other Name: 90 degree elbow, right angle bend, love and bend and so on.
Elbows are split into two groups which define the distance over which they change direction; the center line of one end to the opposite face. This is known as the "center to face" distance and is equivalent to the radius through which the elbow is bent.

90°-LR : = 1½ x 2(NPS) x 25.4 A=76.2 mm 180°-LR : = 2 times the 90° LR elbow A=152.4 mm
90°-SR : = 2(NPS) x 25.4 A=50.8 mm 180°-SR : = 2 times the 90° SR elbow A=101.6 mm The center to face distance for a "long" radius elbow, abbreviated LR always is "1½ x Nominal Pipe Size (NPS) (1½D)", while the center to face distance for a "short" radius elbow, abbreviated SR even is to nominal pipe size.
