Pipe Fittings Elbow 90° Alloy Pipe Fitting Elbow DN15-1200 Is Very
Versatile
Alloy elbow is a general term for a variety of elbows. It is used
to connect two pipes with the same nominal diameter to make the
pipe bend at 90° or other angles. It is made of various materials
and alloy elbows are very versatile.
Ordinary bronze alloy elbows are more common in general tap water
pipes, but with the improvement of living standards, many tap water
pipes use stainless steel elbows.
Hot forming
The hot push elbow forming process is to use a special elbow push
machine, core mold and heating device, so that the blank sleeved on
the mold moves forward under the push of the push machine, and is
heated, expanded and bent during the movement. the process of. The
deformation characteristic of the hot push elbow is to determine
the diameter of the tube blank according to the law of constant
volume before and after the plastic deformation of the metal
material. The diameter of the tube blank is smaller than the
diameter of the elbow, and the deformation process of the blank is
controlled by the core mold, so that the inner arc is compressed
The metal flow is compensated to other parts that are thinned due
to diameter expansion, thereby obtaining an elbow with uniform wall
thickness.
The hot push elbow forming process has the characteristics of
beautiful appearance, uniform wall thickness and continuous
operation, and is suitable for mass production. Therefore, it has
become the main forming method for carbon steel and alloy steel
elbows, and is also applied to certain specifications of stainless
steel elbows. Is forming.
The heating methods of the forming process include medium-frequency
or high-frequency induction heating (the heating ring can be
multi-turn or single-turn), flame heating and reverberatory furnace
heating. The heating method used depends on the requirements of the
formed product and the energy situation.
Stamping
Stamping elbow is the first forming process used in mass production
of seamless elbows. It has been replaced by hot push or other
forming processes in the production of commonly used elbows, but in
some specifications of elbows due to the production quantity Less,
the wall thickness is too thick or too thin.
The product is still used when there are special requirements. The
stamping and forming of the elbow adopts a tube blank with the same
outer diameter as that of the elbow, and is directly pressed into
the mold by a press.
Before punching, the tube blank is placed on the lower mold, the
inner core and the end mold are loaded into the tube blank, the
upper mold moves downwards to start pressing, and the elbow is
formed by the restraint of the outer mold and the support of the
inner mold.
Compared with the hot push process, the appearance quality of
stamping forming is not as good as the former; the outer arc of the
stamping elbow is in a stretched state during forming, and there is
no excess metal in other parts to compensate, so the wall thickness
at the outer arc is reduced by about 10% . However, due to its
suitability for single-piece production and low cost, the stamping
elbow process is mostly used for the manufacture of small batches
and thick-walled elbows.
There are two types of stamping elbows: cold stamping and hot
stamping. Cold stamping or hot stamping is usually selected
according to the material properties and equipment capabilities.
The forming process of the cold extrusion elbow is to use a special
elbow forming machine to put the tube blank into the outer mold.
After the upper and lower molds are closed, under the push of the
push rod, the tube blank is arranged along the inner mold and the
outer mold. The gap movement completes the forming process.
The elbow manufactured by the cold extrusion process of internal
and external molds has beautiful appearance, uniform wall thickness
and small size deviation. Therefore, this process is often used for
the forming of stainless steel elbows, especially thin-walled
stainless steel elbows. The internal and external molds used in
this process require high precision; the requirements for the wall
thickness deviation of the tube blank are also strict.
