The pipeline noise reduction module is currently mainly used on the pipeline between the air cooler and the compressor in the compressor station. During the operation, the airflow velocity inside the pipeline is very high, resulting in airflow noise. The noise generated by the collision between the airflow and the pipe wall is relatively high, about 90dB (A), so that the noises in the factory boundary and at sensitive points in the surrounding area are overproof. Therefore, we have developed this detachable pipeline silencer, which has the advantages of convenient pipeline maintenance, insulation, noise reduction and heat insulation, Usually, the pipeline silencers include several categories: elbow, straight pipe, tee and reducer. According to different requirements, the noise reduction capacity of the pipeline silencer can meet the requirement of 10-30dB (A).
