MTBR is increased when grout and piping are improved. Well-done pipe installations are an art, and most mills have specifications that will work in almost all situations. However, some areas do require expansion joints at pump suction lines. Our team implemented a precision alignment program that uses either reverse indicator, rim and face or laser alignment techniques. My advice is to up the alignment specs.
Most modern facilities use laser or reverse dial indicator methods, which are great.
But remember that the goal is to get the alignment as close as possible, whichever method you use. I am familiar with the standards of .003 TIR for below 1100 rpm and .002 above that speed. In addition, I think balance really makes the difference. Get the best you can. Our vibration program consists of four data collectors.
