Seamless and Semi Seamless Black Painting Buttweld Pipe Fittings
ASME B16.9 elbow has been produced by the pipe . Firstly, we need
cut the pipe into piece and then we put the
elbow om the induction hot forming elbow machine . After forming
the carbon steel elbow and we need to sizing
the carbon steel elbow and after we need d beveling , shot blasting
, painting ,marking and package . Then the
whole process production line will be finished . For the different
size and thickness elbow ,we can get from the
mandrel . Then size different the mandrel different . The thickness
is different and the mandrel is also different .
Different bend radius needs different mandrel . So producing ASME
B16.9 elbow needs many mandrels for different model.

What is a bend?
In piping systems, elbow is the piece of pipe that redirects the
pipe.According to the Angle, there are 45° and 90°180° are the
three most commonly used, and other abnormal Angle elbows such as
60° are also included according to the engineering needs.Elbow
materials are cast iron, stainless steel, alloy steel, malleable
cast iron, carbon steel, non-ferrous metals and plastics.Connection
with the pipe: direct welding (the most common way) flange
connection, hot melt connection, electric fusion connection, thread
connection and socket type connection.According to the production
process can be divided into: welding elbow, stamping elbow, push
elbow, casting elbow, butt welding elbow and so on.Other names :90
degree bend, right Angle bend, love and bend, etc.
1. Since most pipe fittings are used for welding, in order to
improve welding quality, the ends are beveled with a certain Angle
and a certain edge. This requirement is also strict.The surface
mass and mechanical properties are basically the same as the
pipe.For the convenience of welding, the fittings are the same type
of steel as the connected pipe.
2, that is, all the pipe fittings have to go through the surface
treatment, the inner and outer surface of the oxidized iron sheet
through the peening treatment, and then painted with anti-corrosion
paint.This is for export needs, moreover, in the domestic is also
for the convenience of transportation to prevent corrosion and
oxidation, must do this aspect of the work.
3, is the requirement for packaging for small pipe fittings, such
as exports, we need to make wooden cases, about 1 cubic meter,
stipulated that the number of elbows in this kind of box can not
exceed 1 ton, the standard allows the set, that is, large set
small, but the total weight generally can not exceed 1 ton.For
large pieces of y you need a single package, like 24 "you need a
single package.Another is the packaging mark, mark is to indicate
the size, steel, batch number, manufacturer's trademark.
