It is customary to insert a perforated conical strainer into the suction piping of the turbo-compressor that boosts the pressure in natural gas transportation systems. Conical strainers prevent foreign objects, left in the pipeline after its construction, from falling into the compressor impellers. In addition, the strainers are believed to be effective permanent scrubbing devices in most services requiring infrequent cleaning, such as dry and sweet natural gas transportation systems. The strainers that ‘substitute’ scrubbers offer remarkable construction and design savings for the pipeline gas operators, hence, they are often installed in today’s gas transportation systems. A conical perforated strainer could be installed as close as few meters from the compressor nozzle or at a distance of ten to fifteen pipe diameters from it. However, the convenience of strainer installation rather than consideration of its acoustic behaviour frequently dictate its location in the piping system. Therefore, the strainers are usually inserted at the flange sets that are installed for a different purpose, for example, at the spool piece flange sets or at the orifice plate flanges. The strainer location is rarely analysed although it frequently contributes to the acoustical fatigue of piping attachments, strainer disintegration, and spectacular noise generation. In this study, a case of noise generation by a conical strainer is illustrated by noise and vibration measurement results, which were carried out at several different locations of the studied piping system. Noise and vibration spectral components are identified and mitigated by the proposed recommendations.
