Machine anchoring and foundations for connections affected by thermal expansion

Orientering

This standard provides guidance on the design of machine
foundations where connections to rotating machinery are affected by
movements that arise during thermal expansion.
Setting up machinery on traditional fixed foundations, where piping
systems do not have a built-in range of motion, results in thermal
expansion pushing or pulling the machine, reducing the service life of
bearings and seals.
The solution in this standard provides the foundation with the
potential to make small movements itself. As the machine can follow
variations in thermal expansion, this also means there is no need to
realign the machine setup when the system heats up or cools down.
This applies provided that the alignment has been correctly carried
out at the temperature corresponding to the machine’s operating
conditions.
The standard can be used in industry as a basis for project planning
and procurement. The purpose is that affected parties can receive
information about conditions and assumptions at an early stage so
that the design is executed correctly.
