What is the Difference Between Corrugated Compensator and Flexible Metal Conduit?

Jan. 29, 2021

As a Flexible Metal Conduit EMI Proof Factory, share it with you.

Corrugated compensator and flexible metal conduit are pipe fittings that use corrugated pipe as the core element to transport various fluids. Their working nature is to compensate for the connection between pipes and pipes, pipes and equipment, and equipment and equipment. effect. Therefore, people often confuse the corrugated compensator with the flexible metal conduit. In fact, there are certain differences in their working principles. In some occasions where the corrugated compensator and flexible metal conduit cannot be substituted for each other, the unreasonable design will not be able to obtain the expected compensation effect.

Definition of corrugated compensator:

The outer surface of the corrugated compensator has no metal wire or metal belt braided mesh sleeve, and the corrugated expansion joint is equipped with tie rods, hinges, reinforcement rings and other restraint devices, and is an annular bellows assembly with a ratio of less than 3. Corrugated compensators are customarily called corrugated expansion joints in Western countries. Under normal circumstances, the corrugated compensator uses its axial expansion or angle change ratio to compensate for the position movement of the pipeline system caused by the temperature difference. 

The diversification of the classification methods of the corrugated compensator has the following classifications:

a. According to structural characteristics

b. According to performance characteristics

c. According to traditional habits

But no matter which method is used to classify the corrugated compensator, in fact, the products of the corrugated compensator are still diverse and will not increase or decrease due to the different classification methods, but the name has changed. 

The corrugated compensator is also called corrugated expansion joint and corrugated expansion joint. It is mainly used to ensure the safe operation of the pipeline. It has a cylindrical thin-walled corrugated shell with multiple transverse corrugations. Or it can produce displacement under the action of bending moment. The bellows material should meet the following conditions: high elastic limit, tensile strength and fatigue strength to ensure that the bellows work; have good plasticity to facilitate forming and processing, and through subsequent processing to obtain sufficient hardness and strength ; It has good corrosion resistance to meet the requirements of bellows in different environments.

Flexible metal conduit mainly refers to a spiral corrugated pipe, which is a kind of flexible pressure-resistant pipe 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 reduce vibration. It has the functions of good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance, flexibility between pitches, good flexibility, and no blocking and stiffness.
