302.3.6 Limits of Calculated Stresses due to Occa-
sional Loads
a) Operation The sum of the longitudinal stresses
due to pressure, weight, and other sustained loadings
S
and of the stresses produced by occasional loads,
such as wind or earthquake, may be as much as 1.33
times the basic allowable stress given in Appendix A.
For castings, the basic allowable stress shall be multiplied by thecasting quality factor E . Where the allowallowable stress value exceeds two-thirds of yield strength at
temperature, the allowable stress value must be reduced as specified in para. 302.3.2(e). Wind and earthquake forces need not be considered as acting concurrently.
b) Test Stre
Stresses
sses due to test conditions are not subject to the limitations in para. 302.3. It is not necessary
to consider other occasional loads, such as wind and
earthquake, as occurring concurrently with test loads.
302.4
Allowances
In determining
determini ng the minimum required thickness of a
piping component, allowances shall be included for
corrosion, erosion, and thread depth or groove depth.
See definition for c in para. 304.1.l(b).
302.4.1 Mechanical Strength. When necessary, the
wall thickness shall be increased to prevent overstress, damage, collapse, or buckling due to superimposed loads from supports, ice formation, backfill, or
other causes. Where increasing the thickness would
excessively increase local stresses or the risk of brittle
fracture, or is otherwise impracticable, the required
strength may be obtained through additional supports,
braces, or other means without an increased wall thickness. Particular consideration should be given to the
mechanical strength of small pipe connections to piping
or equipment.
PART 2
PRESSURE DESIGN OF PIPING
COMPONENTS
303
GENERAL
Components manufactured in accordance with standards listed in Table 326.1 shall be considered suitable
for use at pressuretemperature ratings in accordance
with para. 302.2.1. The rules in para. 304 are intended
for pressure design of components not covered in Table
Tabl e
326.1, but may be used for a special or more rigorous
design of such components. Designs shall be checked
302.3.6 304.1.1
for adequacy of mechanical strength under applicable
loadings enumerated in para. 301.

304.1.1 General
a) The required thickness of straight sections

b) The following nomenclature is used in the equations for pressure design of straight pipe.

nominal thread depth (dimension h of ASME
