Flange Forging
at low temperature forging changes in size is very small at 700 ℃
forging oxide scale and the formation of less surface decarburization
phenomenon. So as long as the deformation in the forming range of cold forging
easy to get a good dimensional accuracy and surface finish, as long as the
control of temperature and lubrication cooling 700 ℃ the
following warm forging can also get very good accuracy. Forging deformation due
to deformation and deformation resistance can be very small forging complex
shape of the large forgings, to get high dimensional accuracy of forgings in
the 900-1000 ℃ temperature field with hot forging
processing, the other should pay attention to improving the working environment
forging hot forging The die life is shorter compared to forging in other
temperature domains but its freedom is large and low.

flanges
Using the
plate directly cut out the flange mould. Then the flanges processing is volume
of the inner and outer diameter and thickness of the disc, and then bolt holes
and waterline processing. This produced the flange is called cutting flange,
the maximum diameter of such flange is limited by the width of steel plate.
steel shot
Stock of steel shot
Recently because
the coking coal prices keeping up. We had decided to increase the stock rate up
to 80% so that to control the lower prices. In this way, we can keep our price
competitive. We had in been steel shot for many years. The prices from us is
stable and the quality is always as your expected. Your can learn more from
your trial order. Hope we will be your sole supplier in the future.
Carbon steel elbow
Carbon steel elbow’s weight normally are give by factory. As
a buyer how we know the weight of the elbows if the factory didn’t mention it?
There have a computational formula for you. Hope it is helpful. OD means
outside diameter of the elbow. T means the thickness of the elbow. R means the
bending radius. The following method we can know the general weight of a elbow.
Of course the best way is weight directly.

Carbon steel reducer
Carbonsteel reducer have two types: Concentric reducer and eccentric reducer. The
reducer producing tech have three forms. Pressing, Hot expanding, pressing and
expanding.
The
reducer carbon steel material there have ASTM/ASME A234 WPB、WPC
etc. The stainless steel there have :ASTM/ASME A403 WP 304-304L-304H-304LN-304N ASTM/ASME
A403 WP 316-316L-316H-316LN-316N-316Ti etc.
And low temperature steel ASTM WPL6.
Hot expanding Pipe
Hot-expanding pipes
are produced by expanding machine. The technical process is the same as elbow
machine. The difference is the pipe mould is straight and pipe elbow have
bending radius. The advantage of hot expanding pipes is the low prices and easy
to collect the sources. The disadvantage of
the expanding pipes is the wall thickness. The thickness of hot
expanding pipes is not as good as hot roll or cold drawn pipes. The tolerance
is big but within the American standard.
neck flanges
The heavy welding neck flanges are also named heavy WN
flanges, which are hot formed from a circular section of steel plate having a
very small co-axial hole in the flange center. The steel around the hole is
shear-formed downward and outward by a tapered die plug which is forced by the
small hole forming an integral neck on the weld neck flange. A supporting
ring die is radiused at its inner corner to form a suitable fillet radius at
the junction of the neck with the flange proper. A suitable pre-forming or
post-forming operation may be required to compensate for any deflection in the
work piece out of planar configuration.
stainless steel elbows and carbon steel elbows
The difference between stainless steelelbows and carbon steel elbows is the material is different. the chemical
composition of the stainless steel elbows
will keep the elbows for a long time without going into rust, will not be
corroded. Usually it is produced on a high proportion of Cr, Ni and other
alloys. The proportion is up to 20%. Common stainless steel is 304,304L, 321,316/316L,
1Cr18Ni9Ti, 0Cr18Ni9, before several numbers indicate the steel of the U. S.
the last one (1Cr18Ni9Ti) representation for domestic China stainless steel.

well hole. The casing is inserted into the well hole and fixed with cement to
prevent the borehole from separating the rock formation and the borehole
collapse, and ensuring the circulation of the drilling mud to be used for
drilling.
steel pipe material
Q345 is a kind of steel pipe material. It is alow alloy steel (C<0.2%), widely used in bridges, vehicles, ships,buildings, pressure vessels, etc.. Q represents the yield of this kind ofmaterial, the 345 refers to the yield value of this material, in the 345 or so.And the yield value decreases with the increase of the thickness of thematerial. Q345A, Q345B, Q345C, Q345D and Q345E is a class distinction,represented by the temperature, mainly temperature shocks are different, eachclass interval of 20 degrees Celsius, and Q345A level is no impact temperaturerequest; Q345B is 20 degrees ambienttemperature impact; Q345C is 0 degrees impact; Q345D grade is 20 degrees belowzero; Q345E, is - 40 degrees of impact. At different impact temperatures, theimpact values are also different. It is belong to a low alloy series in steelplate. In the low alloy material, this material is the most common. 16Mn isanother name for Q345 in the past.

reducer
Reducer also known as
pipe reducer or reducing straight. One of the chemical pipe fittings for
connecting two different pipe diameters. According to the shape, divided into two
types: concentric reducer and eccentric reducer. The reducer’s materials
include stainless steel, alloy steel and carbon steel. the material that common
used is 20#l, Q235, Q345, 16Mn, ASTM A234 WPB, 12Cr1MoV, 304 or 316 etc.
Spectacle blind flange
Spectacle blind flange also called splay blind plate, just as its name implies, its shape
like a figure eight, one end of it is blind plate. At the other end is by the
throttle loop combination, in fluid delivery, using a throttle ring, cut off
when the blind plate, point like shut-off valve, it can in the leak valve to
cut off. The sealing performance is very good. For systems that need to be
completely isolated, they are generally selected as reliable means of
isolation. Spectacle blind flange should be, before and after, the 2 stop
valve, all in a closed state, the 8 word blank. Common heat exchangers and

Steel butt welded tee,Type Y Tee also named as lateral tee or side
outlet tee. The shape there have two
kinds. One is “Y “ and another is “ y”. It is a kind of irregular pipe fitting
connection in the pipe line system. Because of irregularity, so the type y Tees
normally is made on spot. The tee made by butt welded technology.
Oil casing
Oil casing is a steel pipe that used to
support the oil and gas well wall, to ensure that the drilling process and
after the completion of the normal operation of the entire oil well. Each well
according to different drilling depth and geological conditions, to use a few
layers of casing pipes. After the casing pipe well, it should be used with
cement, which is different from the tubing and drill pipe, and can not be used
repeatedly, which belongs to one time consuming material. Therefore, the consumption
of the casing pipe accounted for more than 70% of all.

carbon Steel elbow
carbon Steel elbow .Definition of long radius and short
radius. Long radius elbow means the bending radius is 1.5d, there also have 3D
elbows. The elbow bending radius that equal or above 3D is called bends. The
short radius elbow means the bending radius is 1D.
Carbon steel Tee
Carbon steel Tee is a kind of pipe fittings. Generally speaking, there have two types, Equal tee
and reducing tee. Equal tee means the branch size is the same as the
main pipe sizes. Reducing Tee means the main pipe sizes is no change the branch
size is different. No matter equal tee or reducing tee, there also have two
types. That is type Y and type y.
steel elbow
No matter what grades of stainless steel elbow it
is, there must contain a certain amount of chromium. So far, there is no chrome
stainless steel. Chromium is to determine the main elements of the performance
of stainless steel, the main reason is that the steel to add more than 12%
chromium as alloying elements, the steel surface will form a very thin
colorless, transparent and very smooth surface, a layer of chromium oxide film
automatically (i.e. passivation film), the formation of this membrane greatly slow
the reduction of oxidized steel.

welding flange
With
a process or a few processes may be completed complex forging finishing.
Because there is no flash, forging the force area is reduced, the required load
is reduced. However, care should be taken not to completely limit the billet,
in order to strictly control the volume of billet to control the relative
position of forging die and forging measurements, and strive to reduce the wear
of forging die. Flat welding flange at low temperature forging, the forging of
the dimensional change is very small. Forging below 700 ℃,
the formation of small oxide, and no decarburization on the surface.
316 and 316L
The
difference between 316 and 316L stainless steel is the difference of carbon
content, L means low. 316L is based on the continued reduction of carbon steel
316L. 316L because of low carbon content, so more corrosion resistance. 316 and
316L is the same but from carbon steel in the need to consume huge energy.
Supply all kinds of steel, complete product specifications, quality and
reliable. Logistics arrangements for free delivery!
cold forging
Hot
forging, the deformation energy and deformation resistance are very small,
forging complex shapes of large forgings. To obtain high dimensional accuracy
of the forgings, in the 900-1000 ℃
temperature domain with hot forging processing. In addition, pay attention to
improve the working environment for hot forging. Forging die life (hot forging
2-5 thousand, warm wrought 1-2 million, cold forging 2-5 million) compared with
other temperature forging is shorter, but it's a large degree of freedom, low
cost .

welding flange
Flat
welding flange should be cut along the direction of the steel rolling strip,
the bending system welded into a ring-shaped, and the steel surface of the
surface of the cylinder. Flat welding flange in the production of steel plates
can not be directly processed into a neck flange, using a certain process of
production and processing. Flat plate welding production of flat steel plate
should be ultrasonic testing, non-hierarchical defects to ensure good quality
and performance problems, in accordance with a certain quality requirements of
production and testing to ensure that the production and use of steel without
any quality problems.
stainless steel
Titanium
is added to the stainless steel. Titanium has a stable chemical properties,
good high temperature, low temperature resistance, acid resistance, alkali
resistance, and high strength, low density, was the reputation as "space
metal." Titanium and oxygen have great affinity, in the air or in oxygen
medium, the titanium surface to produce a layer of dense, strong adhesion,
inert large oxide film to protect the titanium matrix is not corrosion. This
indicates that titanium is a metal having a strong tendency to passivate. Has
excellent wear resistance.

Forging welding flange
Forging weldingflange can be divided into free forging, upsetting, extrusion, die forging,
closed die forging, closed upsetting, closed forging and closed upsetting
because there is no flash material utilization is high . With a process or a
few processes may be completed complex forging finishing. Because there is no
forging to reduce the force of the forging area, to strictly control the volume
of blank control forging die relative position and measurement of forging to
reduce the wear of forging die.
flanges
Forging
at low temperature forging changes in size is very small at 700 ℃
forging oxide scale and the formation of less surface decarburization
phenomenon. So as long as the deformation in the forming range of cold forging
easy to get a good dimensional accuracy and surface finish, as long as the
control of temperature and lubrication cooling 700 ℃ the
following warm forging can also get very good accuracy. Forging deformation due
to deformation and deformation resistance can be very small forging complex
shape of the large forgings, to get high dimensional accuracy of forgings in
the 900-1000 ℃ temperature field with hot forging
processing, the other should pay attention to improving the working environment
