Pipe Elbow
A short radius elbow means that its radius of curvature is equal to
the outside diameter of the pipe, i.e. R= 1.0d.(D is elbow
diameter, R is radius of curvature.D can also be expressed in
multiples.)According to the pressure grade, there are about 17
kinds of pipes, which are the same as the American standard. They
are Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60,
Sch80s, XS.Sch80, Sch100, Sch120, Sch140, Sch160 and XXS, among
which STD and XS are the two most commonly used ones.
According to the Angle of the elbow, there are 45° elbows, 90°
elbows and 180° elbows.These fifittings are for use in pressure
piping and in pressure vessel fabrication for service at moderate
and elevated temperatures.The starting material for fifittings
shall be fully killed steel, consisting of forgings, bars, plates,
sheet, and seamless or fusion-welded tubular products with fifiller
metal added and shall conform to the chemical requirements Carbon
steel elbow is a metal pipe fitting that changes the direction of
the carbon steel pipe.Connection mode: wire buckle and
welding.According to the Angle points, there are 45° and 90°180°
three more commonly used, in addition, according to the needs of
the project also includes 60° and other abnormal Angle elbow.
Elbow materials are cast iron, stainless steel, alloy steel,
malleable cast iron, carbon steel, non-ferrous metal and plastic,
etc.The ways of connecting with the pipe are: direct welding (the
more common way) flange connection, hot melt connection, electric
melt connection, thread 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 names: 90 degree bend, right Angle bend, etcCarbon steel
elbow can be divided into long radius elbow and short radius elbow
according to its radius of curvature.Long radius elbow refers to
the outer diameter of the pipe whose radius of curvature is equal
to 1.5 times, i.e., R= 1.5d.
