Here's What We Do Better
Benefits of Measuring and Correcting
- Avoid future alignment problems
- Increase Efficiency
- Increase mean-time between failure
- This all directly translates into increased profits
ACQUIP knows the significance to having Thermal Growth Monitoring on large machinery aligned at hot and cold operating conditions. It is essential that machines be monitored from cold to hot operating conditions in order to properly adjust for thermal growth and determine the relative torque movements.
Hot alignment checks, theoretical calculations, and manufacturer specifications are useful information provided to perform dynamic movement studies. However, this viable material does not always indicate the absolute condition monitoring process needed on the machine. Dynamic movement is due to a combination of thermal and torsional stresses introduced to the machine after start-up. This procedure is a major component when it comes to preventive maintenance. The only way to compensate for how much these forces affect your machine is to measure them accordingly.
…ACQUIP’s thermal growth monitoring services provide maximum running efficiency and productivity, since It is important to have your machines aligned during running conditions.
We use a laser based monitoring system to increasingly measure the relative movement of your machine from rest to hot operating conditions. This ensures that all dynamic movement is recorded. Accurate alignment targets are reached using the hot alignment procedure.
All data is time stamped in order to correlate alignment changes to events that occur in your process. Our technicians are experts in a wide variety of machines and can accurately measure dynamic movement without damaging your machines. As a result, our condition-monitoring calculations are guaranteed to pinpoint any substantial changes to prevent failure.
We have developed procedures to perform thermal growth surveys on the following machines:
Boiler Feed Pump
The boiler feed pump, is the most common plant machine to have dynamic movement failures. It is essential to measure dynamic movement changes on every boiler feed pump in operation. Obtaining accurate alignment targets for this machine will allow it to operate more efficiently and reduce damage to the coupling, bearings, and seals.
Gas turbines move with extreme temperature changes at the exhaust end. These changes must be compensated for during alignment. We calculate this change with special processes that protect the measuring devices during the survey. The temperature change will affect your turbine but will not affect our equipment, thus enabling us to provide accurate alignment targets.
Our thermal growth monitoring services provide maximum running efficiency and productivity. Applying an RCM (Reliability-Centered-Maintenance) successfully will greatly increase your cost effectiveness, decrease machine downtime and provide a broader view of any potential avoidable risk.

Working with ACQUIP on the job we had in Italy recently was the best experience I have had in this type situation. ACQUIP was very professional and the response time far exceeded my expectations. The rental equipment was in top shape and made it possible for us to take care of our customer in an emergency situation. We will look forward to doing business with you in the future. Thank you for your hard work.
ACQUIP’s engineers performed a great job for Siemens Energy . The Fluid Drive and Gearbox and Pump were all included in the task. Each component was aligned to “all” of Siemens procedures and specifications requested. The Siemens customer was very satisfied with the results of the alignment and process.
First I would like to thank you for your help. We need a piece of alignment equipment on site last minute do to a break down. ACQUIP responded to your request immediately, recommend the right tool for the job, and had the tool on site by 8:30 AM the following morning. Just outstanding customer service and support from the entire ACQUIP team.
ACQUIP was the best choice to rent the Laser Tracker. It speeded up the process! I will definitely come back on our next set of fixtures!
I highly recommend ACQUIP for executing both Tops on/Tops off and Tops off Steam path alignments.
