Operation of centrifugal compressor is affected by many factors and straight pipe section length is one of the important factors. In order to select straight pipe section length of compressor suction,analyzed are straight pipe section lengths of two suctions in certain refrigerant compressor and analysis results show that straight pipe length is affected by molecular weight,velocity and temperature and effective length of straight pipe can be greatly shortened in actual engineering design. ASME standard may not be followed strictly in straight pipe length selection and comprehensive analysis shall be conducted on different actual conditions and determined is the best suitable length.
