1/2" Flexible Stainless Steel Corrugated Tube Stationary Gas Hose
Stainless steel corrugated hose for gas transportation
1. Performance of metal hose:
Corrugated metal hose has many excellent characteristics such as good flexibility, fatigue resistance, high and low temperature resistance, corrosion resistance, etc. It has a much longer life span than other types of hoses (rubber hoses, plastic hoses).

3. Main purpose:
1. Transport corrosive chemical media or organic solvents. (For example: loading and unloading ammonia, acetone, etc.)
2. Convey high temperature medium such as high temperature gas and hot oil. (For example: hot steam, heat transfer oil, etc.)
3. Convey low temperature or ultra-low temperature medium. (E.g. liquid nitrogen)
4. Transport water, steam, oil and other media under high temperature environment. (For example: water vapor system and hydraulic system in coking, steel making, continuous casting equipment)
5. Pipelines that need to absorb vibration or eliminate noise. (For example: the inlet and outlet of the pump)
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.
