PART KD
DESIGN REQUIREMENTS
ARTICLE KD-1
GENERAL
KD-100 SCOPE
a The requirements of this Part KD provide specific
design criteria for some commonly used pressure vessel
shapes under pressure loadings and, within specified limits,
criteria or guidance for treatment of other loadings.
This Part does not contain rules to cover all details of
design.
b A complete analysis, including a fatigue or fracture
mechanics analysis, of all structural parts of the vessel
shall be performed in accordance with applicable Articles
of this Part. All of the loadings specified in the Users Design
Specification see KG-311 and all stresses introduced
by the fabrication processing, autofrettage,
temperature gradients, etc., shall be considered. This
analysis shall be documented in the Manufacturers Design
Report. See KG-323.
KD-101 MATERIALS AND COMBINATIONS OF
MATERIALS
A vessel shall be designed for and constructed of materials
permitted in Part KM. Any combination of those materials
in Part KM may be used, provided the applicable
rules are followed and the requirements of Section IX
for welding dissimilar metals are met, when welding is
involved.
Material design values such as moduli of elasticity, coefficients
of thermal expansion, yield and tensile strength
values, and other material properties are given in Section
II, Part D. With the publication of the 2004 Edition, Section
II Part D is published as two separate publications.
One publication contains values only in U.S. Customary
units and the other contains values only in SI units. The
selection of the version to use is dependent on the set
of units selected for construction.
KD-102 TYPES OF CONSTRUCTION
Article KD-2 contains rules for the basic design of all
pressure vessels within the scope of this Division. Article
KD-2 also provides rules for designing nonwelded vessels
that are constructed of forged or otherwise wrought material
machined to its final configuration.
For openings, closures, and other types of construction,
such as multiplewall and layered, wirewound, or
welded, these rules shall be supplemented by those given
in the appropriate Articles, i.e., Articles KD-6, KD-8, KD-9,
and KD-11.
