Stainless Steel Pipe Co., Ltd. Shandong Jinding analysis: micro-perforated plate muffler is usually less than pure metal sheet with a thickness of 1mm production, on the plate with a diameter less than 1mm drill perforation, perforation rate of 1% to 3%. Select a different perforation rate and deep cavities having different thicknesses spiral welded perforated tube, can control the spectral properties of the muffler, so that to obtain good results in the muffler desired frequency range. Shandong Jinding Stainless Steel Pipe Co., Ltd. mainly produces stainless steel "car exhaust system with pipes, pressure vessels tubes, boiler heat exchanger tubes, condenser heat exchanger tube" stainless steel coil, stainless steel U-tube, stainless steel threaded pipe, Stainless Steel Corrugated Tube, pipe and other types of industrial stainless steel tube. Stainless Steel Pipe Co., Ltd. Shandong Jinding Resolution: holes muffler structure is a closed-end straight punching spiral pipe, drilled a lot of holes on the wall. Muffler hole principle is based on the spectrum of jet noise, and if you keep the spout of the total area of ??the same but with a lot of small vents instead of punching tube, when gas flow through a small hole, the spectrum will be moved to the high jet noise frequency or ultra high frequency, the spectral components in the audible sound was significantly reduced, thereby reducing interference and damage to human.
