1. What is a corrugated stainless steel tubing/pipe?
A metal hose consisting of stainless steel plates that have been corrugated by a forming machine and then welded or crimped is known as a stainless steel corrugated pipe. It can bear significant pressure and impact loads and exhibits properties including high-temperature resistance, corrosion resistance, pressure resistance, high strength, and no deformation.
Bellows made of stainless steel come in single-layer and multi-layer varieties. The multi-layer bellows' inner and outer layers are made of stainless steel, and the intermediate layer is composed of a specific material that serves as an insulation and buffer to increase the bellows' resistance to pressure, resistance to wear, and flexibility.
Stainless steel corrugated pipe is installed in the liquid transportation system as a flexible pressure-resistant pipe fitting to account for the mutual displacement of the connecting ends of pipes or machines and equipment, absorb vibration energy, and possibly reduce vibration and noise. Numerous other qualities include high and low-temperature resistance, fatigue resistance, corrosion resistance, superior flexibility, and lightweight.

6. Applications and characteristics of corrugated stainless steel tubing/pipe
Performance characteristics of stainless steel corrugated pipes
1. High pressure and corrosion resistance: The stainless steel bellows are lined on the inside with a unique polyurethane material and are constructed from high-quality stainless steel on the outside. It can endure high pressure and has the qualities of corrosion and oxidation resistance.
2. The stainless steel bellows material has outstanding high-temperature resistance since it has undergone high-temperature treatment. It can function in hot conditions without warping or cracking.
3. Outstanding mechanical qualities: Stainless steel bellows use a bellows design, which has outstanding flexibility and elasticity, can endure pressure and absorb vibration, decrease strain at pipe joints, and significantly lengthen the service life of pipe fittings.
4. Quick and simple installation: Stainless steel corrugated pipes are lightweight, flexible, simple to bend and install, and may be cut to the precise lengths required.
Application range of stainless steel corrugated pipes
1. Petroleum industry: suited for conveying corrosive media, different chemicals, oil, and oil and gas mixes.
2. Chemical industry: appropriate for pipeline compensation, connection, and transportation of corrosive media and diverse chemicals.
3. Food industry: able to transport a variety of foods and medications with strict food hygiene regulations.
4. The pharmaceutical business, which has strict standards for cleanliness and hygiene, is suited for carrying a variety of preparations, biochemical medications, and biological products.
5. The electric power sector is well suited for moving water and other types of media at high pressures and big flows.
