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.

steel elbow
Carbon steel elbow forming
process is the use of special elbow push machine, mandrel and heating device,
in order to achieve set in the blank on the die in the pushing machine driven forward,
in the movement was heated, diameter and bending Forming process.
seamless tube
Q345A
seamless tube grade, is not to do the impact. Q345B level, is the impact of 20
degrees at room temperature. Q345C level, is the impact of 0 degrees. Q345D
level, is -20 degrees shock. Q345E level, is -40 degrees shock. At different
impact temperatures, the values of the impact are also different. Q The yield
strength is not less than 345Mp The quality grade indicates the amount of
impurity elements

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.

The oil casing pipe
The oil casing pipe is a kind of large
diameter pipe, which has the function of fixing the wall of oil and gas well or
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.

iron and steel
Some
media said: "on the guidance" iron and steel industry turnaround has
been approved by the State Council, or after the Spring Festival Officially
issued. The guidance most of the work will be
solved in 2016 ~ 2018 three years time, the iron and steel to capacity, do not
distinguish between corporate ownership.
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
spare, reactor and spare, nitrogen pipeline and process pipeline connection,
etc.. Another feature is the obvious identification, easy to recognize the
status of its installation.

Steel butt welded tee
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.
Grit shot
Characteristics
of steel grit shot: moderate hardness, strength and toughness, impact
resistance, use repeatedly for several times, long service life, good
elasticity, strong adhesion to cleanup the speed quick sand with low
consumption, not broken, cleaning the work piece brightness and technical
effect.

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.
