Premature machine failure can be costly - both in terms of maintenance costs and unplanned
downtime and it makes sense from a bottom-line perspective as well as in terms of optimising
operational efficiencies to take preventive action.
One factor which isn’t widely recognised as being a contributor to premature machine failure is pipe
strain, but it should be. Pipe strain creates stresses on the machine frame or casing which eventually
spreads to the body of the equipment and causes the shaft to become misaligned. Before realigning
the shaft, it’s imperative that technicians identify the causes of misalignment - and that means
checking that the suction and discharge pipes aren’t causing any strain on the machines.
There are basically two types of pipe strain, namely static pipe strain which can occur when the
machines are operating as well as when they are inactive and dynamic pipe strain, which happens
when the machines are running.
The best approach is more than just a shaft alignment system - it should be a total alignment
solution which ensures optimal machine performance. The good news is that a product such as the
Easy Laser shaft alignment system fulfils all the important testing criteria for controlling pipe strain
and aligning shafts in one simple, easy-to-use yet highly accurate package.
The beauty of this device is that it can easily and quickly evaluate whether pipe strain is causing the
shafts to move out of alignment - plus its advanced measuring program enables operators to
investigate the differences between a machine that is operating and one that is static. This is a key
factor in measuring dynamic pipe strain which can be trickier to identify because it’s not a fixed
state, occurring only when the machine and piping are at operating conditions.
Operators using the Easy-Laser can also transfer data to the EasyLink software support package,
which offers a host of useful and value-added features. For example, the software will compute the
data into graphic format, enabling technicians to make better-informed decisions to optimise
If shaft misalignment is costing your operation money, it may well be that pipe strain is to blame.
