Non metallic corrugated compensator 1

Non metallic corrugated compensator is a compensation device used to absorb dimensional changes in pipelines, conduits, or containers caused by thermal expansion and contraction of the elastic elements of the corrugated compensator. It belongs to a type of compensation element

Characteristics of non-metallic corrugated compensator:

1. Compensating for thermal expansion: It can compensate for multiple directions, which is superior to metal compensators that can only compensate in a single way.

2. Compensating for installation errors: Due to the inevitable system errors during pipeline connection, fiber compensators effectively compensate for installation errors.

3. Noise reduction and vibration reduction: Fiber fabrics and insulation cotton bodies themselves have the functions of sound absorption and vibration transmission, which can reduce the noise and vibration of systems such as boilers and fans.

4. No thrust: Due to the main material being fiber fabric, there is no force to transmit. Using fiber compensators can simplify the design, avoid using large supports, and save a lot of materials and labor.

Testing of non-metallic corrugated compensators:

Due to the different compensation forms of different types of corrugated compensators, there are mainly axial, transverse, angular, and combined compensation methods. For corrugated compensators with multiple displacements simultaneously, it is necessary to synthesize their various displacements and calculate the total equivalent axial displacement. Detection is based on the total equivalent axial displacement. That is to say, the detection of the nominal displacement of the corrugated compensator is the detection of the total equivalent axial displacement.

The nominal displacement of a universal corrugated pipe is actually the ability of the corrugated pipe to deform under the given nominal displacement. For expansion joints (compensators) and compensators made of corrugated pipes, they are usually referred to as compensation quantities, which reflect the ability of the corrugated pipe to absorb system displacement and indicate the large compensation capacity of the product under certain conditions. During normal operation, corrugated pipes need to absorb system displacement and generate displacement deformation, while also requiring a certain number of normal working displacement cycles. Therefore, in the design of corrugated pipes, the number of ripples is determined based on the displacement that each wave can withstand. When each wave is uniformly subjected to displacement load without local overload, the corrugated pipe can work normally. At this time, the number of working displacement cycle life cycles can be designed. In the JB/T 6169-92 "Metal Bellows" standard, provisions have been made for the testing of this performance.
