One pipe has multiple joints to avoid the trouble of choosing gas
pipe joints.
The joint is disassembled and analyzed, and it can be easily
perforated.
The joint stainless steel nut, equipped with a circlip and a
sealing gasket, is perforated and penetrates the wall,
and the hole diameter must be ≥16 mm.
The joints are thickened to prevent bursting and improve the safety
factor.
Cold and frost-resistant, high temperature resistance, also
applicable to extreme cold weather at minus -30°C,
PVC flame-retardant outer skin, 304 stainless steel high
temperature resistance.
The length can be customized, the length is optional, the threaded
type 304 stainless steel, and the plasticity is
free and easy.
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. |  |
