Stainless steel corrugated hose for gas transportation
1 and 304 belong to a stainless steel bellows. The life span of
this gas bellows can reach over 50 years, because it has anti-aging
effect. If the family chooses rubber bellows, but it is easy to
break in a humid environment and will gradually age, but the 304
stainless steel gas bellows will not have this aging problem.
2. 304 stainless steel bellows also has the characteristics of high
temperature resistance, but the rubber hose does not have this
advantage. It is easy to soften under the fire, and even the risk
of fire, while the stainless steel bellows is very high temperature
resistant.
3. In addition, it also has corrosion resistance. Stainless steel
adopts 304, which can cope with general corrosive liquids. It also
includes the protective layer of PVC, which also plays the role of
anti-corrosion and flame retardant. It is precisely because the 304
stainless steel gas bellows have corrosion resistance, high
temperature resistance and anti-aging effect, so its service life
has reached 50 years. Compared with ordinary rubber hose, its
service life is several times longer.
Product Features
1. Flexible ways of installation and beautiful layout, such as It
can be installed in the open, in the dark,
through the ceiling or embedded in the wall, the laying method is
flexible and diverse, and the installation
effect is beautiful.
2. The internal metal hose is made of S30408 austenitic stainless
steel, which is corrosion-resistant and
non-aging, with a designed service life of more than 50 years.
3. The design of air grooved plastic sleeve is easy for monitoring
leaking.
4. It is with compensation, good shock resistance, resistance to
thermal expansion and contraction, and
resistance to uneven settlement., as well as excellent high
temperature resistance, low temperature
resistance and fire resistance.
5. Light weight, good bending performance, free length choices,
simple installation.
Highlights of Product —— SAFE USE OF GAS FOR THE WHOLE FAMILY
01/ Protective sleeve,flame-retardant material Outer sleeve adopts insulating and flame-retardant material, which
effectively prevents burning, and it is automatically extinguished
without fire sources. |  |
 | 02/ SS304 hose, rat bite-proof The high-strength SS304 hose is with high pressure bearing, can
also effectively prevent gas leakage caused by rat bites |
03/ Thick copper pipe, well connection seal The pipe fittings are made of HPb59-1 copper, electroplated
surface, built-in sealing rings (NBR rubber), with excellent
sealing performance. |  |
 | 04/ Super flexibility, bend at will The design of corrugated hose secures its very good flexibility,
bend at will, convenient installation. |
05/ Air grooves The cover sleeve with air grooves can guide the leaking gas to flow
to the detective hole at the connecting ends, for purpose of
accurate monitoring. |  |
