API 686
Recommended Practice for Machinery Installation and Installation Design
How rotating machinery is installed: foundations and grouting, soft foot, piping strain, and the cold alignment offsets that bring a machine into alignment once it has grown to running temperature.
This is an explanation, not the standard. PipingInspector is not affiliated with API and reproduces no part of the document. Always work to the current edition of the standard itself and to your project specification.
