As a Flexible Conduit Factory, there is some information
to share with you.
Pipe installation stress
In complex piping systems, there are often difficulties due to space
position conditions, resulting in installation difficulties: the formed pipe can
not be loaded; bending over, coming over, making up the installed pipe will
inevitably produce local Cold correction. Depending on the pipe diameter and the
specific conditions on site, the amount of cold correction ranges from a few
millimeters to tens of millimeters, and some hundreds of millimeters. Practice
has proved that the larger the amount, the higher the internal stress, and the
installation stress of these residues in the pipeline system is undoubtedly
extremely invisible.
A section of the bearing lubricant pipe in a certain type of engine has
many fracture accidents in actual operation, which is caused by excessive
installation stress.
Because it can be bent at will and the internal stress generated by bending
under the rated bending radius is very small, it can bring great convenience to
the installation work and also guarantee the safe operation of the pipeline
system. This is the main reason why certain piping systems must use
Flexible Metal Conduits.

Compensation pipe position
Due to the need to load and unload the mold, the movable cylinder on the
vulcanizer will move in the upward and downward directions. After the copper
serpentine tube reciprocates many times, fatigue fracture occurs, although it
can be used after repair, but the parking repair will cause time loss. Although
the rubber tube has good softness and strong anti-fatigue ability, it is also a
weak link in terms of pressure, temperature resistance and anti-aging. It can
not be continued after several months of use. The good overall performance of
the metal hose is fully reflected here. In the general industrial field, in
addition to pressure and temperature, there are often harsh conditions such as
fatigue, corrosion, vibration, pressure, impact, etc. Under such circumstances,
it is most suitable to compensate the positional movement of the pipeline. It’s
gone.
Absorbing vibration
In a giant building, the air conditioning in the hall is provided by a 6FWB
unit fixed in the basement. The vibration of the unit passes through the bridge
connecting the pipe and is transmitted to the ground hall, with a noise value of
45dB. In such an environment, people always feel a sense of discomfort. After
the design is improved, the metal hose is connected in series on the connecting
pipe, which not only absorbs some of the noise generated by the vibration of the
unit, but also the noise generated by the fluid pulsation in the pipe system is
absorbed. At this time, the noise in the ground hall The value is only 33dB,
which greatly improves the environment inside the hall.
The corrosion resistance of Flexible Stainless Steel Conduitdepends on the content of chromium. When the amount of chromium added
is 10.5%, the atmospheric corrosion resistance of steel is significantly
increased, but when the chromium content is higher, although the corrosion
resistance can be improved, But not obvious. The reason is that when chromium is
used to alloy steel, the type of surface oxide is changed to a surface oxide
similar to that formed on pure chromium metal. This tightly adhering
chromium-rich oxide protects the surface from further oxidation. This oxide
layer is extremely thin, through which you can see the natural luster of the
stainless steel surface, giving the stainless steel a unique surface. Moreover,
if the surface layer is damaged, the exposed steel surface will react with the
atmosphere to repair itself, and the "passivation film" is reformed to continue
the protection.
