How to Use the Thermal Expansion Table:
Example: Find the expansion 0f 105ft. Of any diameter
carbon steel pipe carrying steam at 138 PSIG and at a
lowest surrounding ambient temperature of 40°F.
 Maximum temperature = 360°F
(138 PSIG saturated steam)
 Calculated traverse (from table)
Expansion per 100 ft. of carbon steel at 360°F = 2.88”
Expansion of 105 ft. = (105 / 100) x 2.58” = 2.71”
Conclusion: Since an expansion joint is normally set at
80% in compression and 20% in extension, an expansion
joint with 4” total axial movement should be selected.
NOTE: The shaded area indicates the maximum
and minimum recommended temperature for
each material. For applications requiring lower
or higher temperatures, consult the factory.
From the Piping Handbook by Sabin Crocker,
McGraw-Hill Publishing Co. & Acme Paper No.
53-A-52, 1954.
NOTE: Expansion joints are not designed to
absorb torsional movement or stress. Subjecting an expansion joint to torsion of any amount
may drastically affect operating life and will
void the warranty. Consult factory if torsion is
present.
