PVC Coated Stainless Steel Corrugated Bellows Hose for Natural Gas
The stainless steel gas bellows has the characteristics of convenient installation, reliable connection, corrosion
resistance, no gas blocking, good flexibility, long service life, and can be bent at will without deformation and
no gas blocking. The outer layer of the bellows is covered with a yellow PE layer, which can be Anti-corrosion,
insulation, heat resistance, prolong service life and beautiful appearance.
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. |  |
