Stainless Steel Flex Metal Pipe with Quick 304 Adaptors for Natural
Gas
Stainless steel corrugated hose for connection of gas appliance
1. Purpose:
Water is injected into the coal to discharge gas.
2. Features:
1. Water enters the coal body and releases some gas, which
effectively reduces the gas content in the coal body.
2. After the effect of water injection is achieved, the dust can be
reduced by more than 80%, the working environment of workers can be
improved and dust accidents can be prevented.
3. Moisten coal, reduce pyrotechnic products, reduce costs and
improve workers' sense of safety;
4. Play the role of outburst prevention, effectively release
in-situ stress and gas pressure, and prevent outburst accidents in
the process of coal mining.
5. The problem of excessive gas during coal cutting and outburst
prevention drilling is solved, which can effectively prevent the
sudden explosion of coal and gas.
3, Structure:
The sealing machine is composed of high-pressure rubber expansion
hose, intermediate steel pipe, sliding sealing joint and pressure
injection joint
Product Features
1. High-quality imported 304 stainless steel, with nickel content
≥8.0%, over 50 years of service life of the
stainless-steel pipe body.
2. Deeper and denser corrugation, with better flexibility and
safety.
3. Integrated pipe fittings and pipes, making the installation
easier and faster;
4. Short and hidden tube neck inside the tube, good protected and
invulnerable to damage
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. |  |
