centrifugal compressor vibration testing, analysis and limits based on API Std. 617.&nbsp;The API 617 only requires the vibration being measured at shaft adjacent to the bearings during the&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/centrifugal-compressor-aerodynamic-testing\/\" target=\"_blank\" rel=\"noopener\">aerodynamic performance test<\/a>&nbsp;and in the&nbsp;<a href=\"https:\/\/ptrotek.wordpress.com\/centrifugal-compressor-testing\/\" target=\"_blank\" rel=\"noopener\">mechanical running test<\/a>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The proximitor probe is used for measurement and usually is handled by 4 probes, two for suction bearings X and Y axises and two for discharge bearing same X and Y axises.<\/p>\n\n\n\n<figure

per API 617, the maximum allowed overall vibration shall be&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u221a(12000\/N) or 1.0 mil whichever is less (N is the Rotor Speed)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">for example, if your centrifugal compressor speed is 18000 rpm, the maximum allowed vibration amplitude is \u221a(12000\/18000) = 0.87, so the 0.87 is less than 1 then maximum allowed vibration amplitude for your compressor is 0.87 mil<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The API 617 also requires that the discrete nonsynchronous vibration shall not be more than 120% of maximum allowed value for overall vibration.&nbsp;<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright is-resized\"><img decoding=\"async\"

example, the maximum allowed discrete nonsynchronous vibration is 1.2 x 0.87 = 1.044 mil<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Please note this concession is for nonsynchronous vibration and does not apply for synchronous discrete vibration. In above example, the vibration amplitude at the frequency of 18000 cpm or 300 Hertz(which is synchronous frequency) shall be maximum 0.87 mil (the same as overall vibration)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The API 617, also requires at any speed greater than MCS up to trip speed, the discrete vibration shall not increase more than 0.5 mil above recorded value for MCS just before increasing speed to the trip speed.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The standard also requires the frequency range be in the range of 0.25 to the 8 times of the MCS.

The vendor must submit a Root Cause Analysis (RCA) and proposed disposition (Rework, Repair, or Concession). Work on the affected component is halted (Hold Point) until the Owner&#8217;s engineering authority approves the disposition and a re-inspection confirms full compliance.<\/p>\n    <\/div>\n\n    <div style=\"margin-bottom: 20px;\">\n      <h3 style=\"font-size: 16px; color: #1e3a8a; margin-bottom: 6px;\">Q: What is the difference between Witness (W) and Hold (H) points in an Inspection &#038; Test Plan (ITP)?<\/h3>\n      <p style=\"color: #334155; line-height: 1.6; margin: 0;\"><strong>A:<\/strong> A Hold Point (H) is a mandatory milestone where fabrication or testing CANNOT proceed without the physical presence of the designated client or third-party inspector. Written clearance or stamping is strictly required. A Witness Point (W) requires prior notification (typically 24 to 48 hours) to the inspector; however, if the inspector fails to attend at the scheduled time, fabrication or testing may proceed with subsequent review of the test records.<\/p>\n    <\/div>\n\n    <div style=\"margin-bottom: 20px;\">\n      <h3 style=\"font-size: 16px; color: #1e3a8a; margin-bottom: 6px;\">Q: Can international clients review inspection reports and photos in real time?<\/h3>\n      <p style=\"color: #334155; line-height: 1.6; margin: 0;\"><strong>A:<\/strong> Yes.
