EJMA Section 4.10.2 provides an empirically derived formula for internal sleeve thickness as follows:
tmin = t(based on diameter) x (V/100ft/s)^2 x (L/18")^2 x E300F/Etemp
where:
t is .06" for 26" to 48" diameter (my particular case)
V is fluid velocity if greater than 100 ft/s
L is length if longer than 18"
E is modulus of elasticity of liner if fluid temperature exceeds 300 degF
Has anyone found a theoretical basis for this formula?
