Stainless steel corrugated pipe, as a kind of flexible pressure-resistant pipe, is installed in the liquid conveying system to compensate for the mutual displacement of the connecting ends of pipes, machines and equipment, and absorb vibration energy. It has the characteristics of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance, etc. Below with the small make up to understand the stainless steel bellows!

　　1、 Advantages of stainless steel bellows

　　1. Good workability: stainless steel corrugated hose is thin-walled hose, which reduces the overall weight and greatly reduces the construction load and construction time.

　　2. Corrosion resistance: the main body of corrugated pipe is made of 304 or 316L stainless steel, and both ends are made of stainless steel joint or carbon steel joint, which has good corrosion resistance. The sealing is ensured.

　　3. High pressure resistance: various factors such as actual working pressure, service environment and service condition of bellows are considered. All parameters have been carefully calculated and repeatedly tested to ensure its pressure safety in work.

　　4. Variety: the existing corrugated pipe diameter range: dn8-dn4000, others are customized according to customer requirements.

　　5. Shockproof and anti dislocation: stainless steel corrugated hose has good flexibility and displacement compensation characteristics.

　　6. Appearance beauty: the appearance is clear and bright, and the permanent brightness is as new.

　　7. Earthquake resistance and high speed

　　8. It can transmit torque. In the operation of ordinary mechanical seal, the structure of transmission seal must be added

　　9. Few leakage points.

　　2、 Disadvantages of stainless steel bellows

　　Twisting back and forth may cause metal fatigue, artificial damage or leakage of threaded joint, so stainless steel corrugated hose can not be twisted back and forth. If it exceeds 2m, it needs to be fixed. After the mechanical injury caused by external force, we can not judge whether there are cracks or stress concentration by naked eyes, so it must be replaced.
