Rust-proof
and corrosion-resistant lining stainless steel composite pipe
1. Has good mechanical properties:
Because the inner and outer layers are made of metal materials, it
has strong compressive and impact resistance, high tensile
strength, high elongation, high elastic modulus, and low thermal
expansion coefficient. It is especially suitable for risers and
branch pipes of high-rise building water supply. .
2. High bonding strength:
The lining stainless steel composite pipe is to sleeve the inner
stainless steel pipe into the carbon steel pipe. Under the action
of mechanical squeezing force, the outer carbon steel pipe is
elastically deformed, and the inner stainless steel pipe reaches
plastic deformation, so that the two layers of materials are
tightly fitted. Its bonding strength exceeds the requirements of
the national industry standard and reaches more than 1MPa. Because
the inner and outer layers are similar in materials and have strong
bonding force, there will be no peeling of the two materials during
groove pressing and cutting, preventing the occurrence of galvanic
corrosion.
3. Good rust and corrosion resistance:
The stainless steel material has chemical properties such as
anti-rust and oxidation resistance, acid and alkali resistance, and
good intergranular corrosion resistance, and its anti-rust and
anti-corrosion performance is superior to other materials. The
lining stainless steel composite pipe and the lining stainless
steel composite pipe fittings are connected with a wider range of
applications. They are mainly used for water supply, heating, air
conditioning, fire protection, chemical industry, medicine,
petroleum, food, electric power, metallurgy and other high
anti-corrosion requirements. industry.
4. Heat-resistant and cold-resistant, dual-purpose cold and hot:
The working temperature of temperature-resistant stainless steel
can reach -40℃-350℃. The cold resistance performance is also very
good. For example, the liquid chlorine freezer uses stainless
steel, so the stainless steel composite pipe lined with excellent
heat resistance and cold resistance, and regardless of the hot and
cold water pipes, one pipe is used for two purposes, both cold and
hot.
5. Large diameter and low resistance:
The inner layer of stainless steel composite pipe lined with
stainless steel is only 0.25~0.7mm, so the actual diameter is
basically in line with the specified diameter, and the inner wall
is smooth, sanitary, non-scaling, small in resistance, and large in
water flow.
6. High working pressure:
The lined stainless steel composite pipe has good rigidity,
pressure resistance, no leakage, and can ensure the working
pressure ≥2.5MPa, ≤3.5 MPa, which can meet the needs of various
construction projects.
7. Convenient installation and simple process:
The installation of lining stainless steel composite pipe is
equivalent to ordinary galvanized steel pipe, wire connection is
used for DN100 and above, groove connection is used for DN100, the
process is simple, installation workers do not need special
training, the probability of joint leakage is almost zero, safe and
reliable, and easy to maintain.
8. Sanitation and environmental protection, good safety:
As the stainless steel material has stable chemical properties and
no harm to the human body, the various brackets, splints, and
internal fixation screws implanted in the human body in the
international and domestic medical circles are all made of
stainless steel. The lined stainless steel composite pipe is
connected with the composite pipe fittings, and the threads and end
faces of the joints are coated with anticorrosive liquid, which can
effectively prevent secondary pollution to the water quality. The
fluid transmission part of the lining stainless steel composite
pipe system is all made of stainless steel, which is hygienic,
environmentally friendly, safe, and has a long service life, in
line with the development requirements of "ecological residence"
and the people-oriented concept of the times.
Application areas of lining stainless steel pipes:
(1) Water supply introduction pipe
(2) Outdoor water supply pipes
(3) Pipes for pump room
(4) High-rise building water supply pipes and water distribution
main pipes
(5) Air conditioning circulation pipes and fire sprinkler pipes
(6) Hot water pipes, direct drinking water pipes
(7) Water supply pipes for finely decorated high-end commercial
houses, etc.
