A403 GR WP304L SS Elbow, SCH 80, 90 Deg, LR, Wrought, Black
In the pipeline system, the elbow is a pipe fitting that changes
the direction of the pipeline. 45 and 90 by angle Three of the most
commonly used, in addition to engineering needs including 60 other
abnormal angle elbow. The 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, thread connection and socket connection. According to
the production process can be divided into: welding elbow, stamping
elbow, push elbow, casting elbow, butt welding bend, etc. Other
name :90 degree bend, right angle bend, etc.
Process flow
Seamless elbow: elbow is a pipe fitting used at the bend of a pipe.
The largest proportion of all pipe fittings used in the pipeline
system is about 80. Usually, different forming processes are
selected for bends with different materials or wall thickness. The
seamless elbow forming process used by the manufacturer is hot
push, stamping, extrusion and so on.
Medium plate welding
Use a medium plate to make half of the elbow section with a press,
and then weld the two sections together. A process such as this is
generally used as a bend above the DN700.
Folding other forming methods
In addition to the above three commonly used forming processes,
seamless elbow forming also adopts the forming process of extruding
the tube billet into the outer die and then passing through the
ball shaping in the tube billet. However, this process is
relatively complex and difficult to operate, and the forming
quality is not as good as the previous process, so it is less used
