6% Thickness Tolerance Hydraulic Elbow Carbon Steel Buttweld A234
Wpb Seamless Pipe Fittings
For the carbon steel elbow, Manufacturers commonly used seamless elbow forming process hot push, stamping, extrusion and so on.The
hot-bending bending head forming process adopts a special elbow
pushing machine, a mandrel and a heating device, so that the billet
placed on the die is moved forward by the pushing machine, heated,
expanded and bent during the movement. the process of. The
deformation characteristics of the thermal pusher elbow is to
determine the diameter of the blank according to the constant
volume before and after the plastic deformation of the metal

Our company is producer and exporter of all kinds of carbon steel pipe fittings.Our city is the hometown of carbon steel pipe fittings.everyday
lots of containers of fittings are dispached all over the
world,such as Russia,Egypt,Malaysia,India,Turkey,Indonesia,Jordon
and some other overseas markets.Our company monthly dispach around
50containers fittings.We provide our customers with one-stop

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.
By the production method can be divided into push system, pressing,
forging, casting and so on.
It can be divided into national standard, electrical standard, ship
standard, chemical standard, water standard, American standard,
German standard, Japanese standard, Russian standard and so on.
According to its radius of curvature, it can be divided into long
radius elbow and short radius elbow.The long radius elbow refers to
the outer diameter of the pipe whose radius of curvature is 1.5
times, that is, R= 1.5d;The 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 the diameter of the elbow and R is the radius of
According to the pressure level, there are about 17 kinds, which
are the same as the American pipe standard :Sch5s, Sch10s, Sch10,
Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, SCH100,
Sch120, Sch140, Sch160, XXS;The most common ones are STD and XS.
