material of Steel pipe,and Method of use
1. The product description
Composite stainless steel cold-rolled steel sheet is based on
deep drawing steel or the user to
specify other carbon steel as base layer, on both sides of the
overall continuous a certain
thickness of stainless steel cladding, and with hot rolling and
cold rolling and special steel. Can be
widely used in building Windows and doors, curtain wall, light
industry, food, medicine and health
care, environmental protection and other departments. In recent
years in the field of building
doors and Windows, curtain wall, welded pipe applied are
exploring in advance.
The application of new products Petroleum & Natural Gas
pipeline in foreign countries, there is no
report, also have no special standard to guide. Japanese
JISG3601 stainless steel standard
stipulated in the range of products for more than 8 mm, not
including sheet and strip not including
cold rolled products. The ANSL/ASTNA263 corrosion resistant
chromium steel composite plate,
BoGang and steel belt standard specifications stipulated in the
range of 2.7 MM * 254 MM hot
rolled plate and 2.73 MM * 609.6 MM manufacture, both in the
same standard of hot rolled plate
and manufacture, and this material is usually only used pressure
vessel. Released in November
1997 in our country composite cold rolled stainless steel plate
and steel belt of national standard
(GB/T17102-1997) is the international and domestic the product
and the first generation standard,
its application scope mainly focus on civilian and the pressure
vessel.
2. Product specifications

3. The application and market prospect
Composite plate and the application of composite sheet (with)
are the two wheels of stainless
composite plate application; The applications of industrial and
civil is its two wheels. Composite
plate is mostly applied in industry; Composite sheet (with) are
mostly applied to civilian use.
People often in attaches great importance to the composite steel
industrial application at the
same time, ignore the application of it in civil projects, this
leads to a composite plate appeared
while the phenomenon of market development. In fact, cold rolled
stainless composite BoGang
belt in People's Daily life can be a lot of project application,
the dosage should be greater than the
composite plate is mainly used in industry.
(1) the application of construction industry
As for doors and Windows in buildings and high-grade materials,
functional, decorative and craft
improvement of the items, stainless steel cold-rolled steel
sheet will be the future high-rise
buildings, coastal building material of choice for the best.
Stainless steel doors and Windows
more than aluminum alloy doors and Windows with high wind load
strength, thermal insulation
and corrosion resistance, etc, but to feel headache is stainless
steel doors and Windows
manufacturer of high strength, residual deformation in the
process of rolling material, dimension

precision is difficult to control, and stainless composite steel
plate because of the carbon steel
substrate and the cladding material and design makes the cold
hardening greatly reduce garden
corner radius bending workpiece shape beautiful, foster
strengths and circumvent weaknesses,
so it is the most has the development potential of the new type
of high-grade door window
material, has been favored by selected comer in construction
industry. The recent demand for
20000 tons/year, medium-term demand for 100000 tons/year.
In addition, senior high-grade building outside the curtain wall
is to improve the building
decoration, rich of the key parts of the city landscape, due to
the stainless steel curtain wall
adornment effect is good, its elegant style, lively, bright,
eye-catching, safe and reliable, add
luster to the whole building and strength, and therefore has
become the trend of China's
architectural decoration. Keeping all stainless steel composite
plate in its, on the basis of the cost
is greatly reduced, thus skeleton curtain wall will be the best
choice of materials. The recent
demand for 2000 tons/year, medium-term demand for 10000
tons/year
Western countries stainless steel curtain wall and external wall
in the 50 s, but the real cause of
global concern or in the late 80 s, mostly due to the amount of
each construction project in 1000 ~
2000 tons, so each competition is very fierce. Stainless steel
frame glass curtain wall in China,
with its luxurious luxuriant appearance, strong corrosion
resistance, little maintenance cost, and
high strength, long life characteristics such as the architect
and the user's attention, is very
promising. Nearly two years in our country every year 5 million
~ 6 million M2 of curtain wall
installation, 12 kg per square metre frame calculation, need
72000 tons of steel, stainless steel
composite plate with its superior stainless steel machinability
and 50% lower thermal expansion
coefficient and the surface of the same quality, low 30% ~ 40%
of the price, the market's appeal is
obvious, such as can have 10% or 7200 tons has been a very
considerable number.
Buildings in our country every year during 95 to 80 million M2,
window ordinary steel SeamlessSteel Pipe window color plate steel
window 40%, 15%, 33%, other 12% aluminium window of
model steel window, of which only 0.6% of the stainless steel
window, press computation of 9
kg/M2, need 4320 tons of stainless steel. This what high
strength stainless steel, not rusting,
luxurious and elegant advanced materials promote trudging on
doors and Windows? The reason
as the analysis of the main leaders of China institute of doors
and Windows; "Fundamental" type
stainless steel doors and Windows village development: one is
forming, the stainless steel cold
work hardening is large, the springback, rolling are difficult,
contorted, transition arc, profiles to
meet the standards; 2 it's hard to keep the surface quality,
board face the more light, the more
visible defects and uneven, processing difficult to set a
window, it is still associated with high
strength; 3 it is all stainless steel price is high. The
stainless composite steel plate can be
overcome this "fundamental"; Composite board processing as well
as color plate, can use a set of
mould with color plate, can reduce costs, increase productivity.
With further development, the
price of stainless steel clad plate steel window can be reduced
to 245 ~ 260 yuan/M2, and is
already quite close to the price of aluminium window, and the
using effect is much better.
