Pipe Thermal Expansion Chart

Pipe Thermal Expansion In Inches Per 100 feet​

The table below shows expansion resulting from change in temperature from 70°F to indicate temperature. This table is to used as an informational guide only, and it is not implied that materials are suitable for all temperature ranges shown. Data for Inconel is based on information provided by the International Nickel Co., and all other data is based on Appendix B of the code for power piping ANSI.
