Instructions and advantages of stainless steel metal hose

Instructions for use of stainless steel metal hose!

Description of components of stainless steel metal hose: Stainless steel metal hose is a high-quality flexible pipe in modern industrial pipelines. Stainless steel metal hose is mainly composed of corrugated pipe, mesh sleeve and joint. The inner tube of the general-purpose stainless steel corrugated metal hose is a thin-walled stainless steel corrugated pipe with low lead mixer Manufacturers a spiral or annular shape. The joints or flanges at both ends of the universal stainless steel corrugated metal hose are matched with the joints or flanges of the customer's pipeline.

The bellows of the hose is formed by plastic processing of extremely thin-walled seamless or multi-welded stainless steel pipes. Due to the elastic characteristics of the contour of the bellows, the hose has good flexibility and fatigue resistance, which makes it easy to absorb cyclic loads of various motion deformations, especially in the pipeline system. It has the ability to compensate for large displacements.

The mesh sleeve is the main pressure-bearing part of the hose installed in the pressure pipeline, and at the same time protects the bellows. According to the pressure in the pipeline and the application place, one or more layers of stainless steel wire or steel belt can be selected for weaving.

Scope of use of the hose: It needs a fully flexible delivery pipe to prevent the piping in the place of vibration, and is used for steam, gas, air, heavy oil, petroleum, chemical drugs, etc.

The advantages and disadvantages of stainless steel bellows are to let us know more about stainless steel bellows and use it reasonably according to its performance. As a flexible pressure-resistant pipe, stainless steel bellows is installed in the liquid conveying system to compensate for the mutual displacement of the connecting ends of pipes or machines and equipment, absorb vibration energy, and can play the role of vibration reduction and noise reduction. It has good flexibility and light weight. , corrosion resistance, fatigue resistance, high and low temperature resistance and many other characteristics. Let's follow the editor to understand the stainless steel bellows!

1. Advantages of stainless steel bellows

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

2. Corrosion resistance: The main body of the bellows is formed of 304 or 316L stainless steel, and both ends are made of stainless steel joints or carbon steel joints, which have good corrosion resistance. Tightness is ensured.

3. High pressure resistance: Considering various factors such as the actual working pressure of the bellows, the use environment and use conditions, all parameters have been carefully calculated and tested repeatedly to ensure the safety of its pressure at work.

4. Various types: Existing bellows diameter range: DN8-DN4000, others can be customized according to customer requirements.

5. Anti-shock and anti-displacement: The stainless steel corrugated hose has the characteristics of good flexibility and displacement compensation.

6. Beautiful appearance: The appearance is clear and bright, and it is as new as ever.

7. Shock resistance and high speed

8. It can transmit torque itself. In the operation of ordinary mechanical seals, a structure for transmitting seals must be added.

9. Fewer leak points.

2. Disadvantages of stainless steel bellows

Twisting back and forth may cause metal fatigue man-made damage or air leakage at the threaded interface, so the stainless steel corrugated hose cannot be twisted back and forth. If it exceeds 2m, it needs to be fixed. After being mechanically damaged by external force, we cannot judge whether it has cracks or stress concentration with the naked eye, so it must be replaced.
