Seamless Pipe Fittings ASTM Forged Butt Welding Carbon Steel Pipe
Fitting Elbow -
- Seamless elbow technology:
Carbon steel seamless elbow forming technology is to choose the
special elbow pipe parts of the push machine, core mold and heating
equipment, so that the blank on the mold in the push machine to
move forward, in the movement of heating, expanding and zigzag
forming process.Hot pushing elbow pipes deformation characteristics
is based on volume before and after plastic deformation rule of
metal materials concluded that tube billet diameter, chooses the
pipe diameter is less than the diameter of the elbow pipe fittings,
through core model control billet deformation process, the arc is
tight spot metal activity, counter to other parts of the thinned by
expanding, then get the uniform wall thickness of elbow pipe
fittings.Hot push pipe fitting forming technology has the
characteristics of beautiful appearance, uniform wall thickness and
continuous work, suitable for mass production, so it has become the
primary forming method of carbon steel, alloy steel and carbon
steel elbow, and also applied in the forming of some standard
stainless steel elbow pipe fitting.The heating methods of the
forming process include medium frequency or high frequency
induction heating (heating ring can be multi-turn or single turn),
flame heating and reflective furnace heating. The choice of heating
methods depends on the demand of the forming commodity and the
power status of the decision.
