3.7 Technical data. The contractor shall prepare drawings and a tech-
nical manual in accordance with the data ordering documents included in the
contract or order (see 6.2.2).
3.7.1 Drawings. In addition to the drawing content required by the
data ordering document (see 6.2.2), the following, unique technical features
shall be included:
Accurately scaled sectional assembly which clearly depicts
(a)
the design and construction of the valve.
Bill of material listing specification, grade, condition, and
(b)
any other data required to fully identify the properties of the
materials.
Dimensions - overall, accessibility space, including disassembly
(c)
clearances, and all other dimensions pertinent to installation.
Estimated weight and center of gravity and any limitations
(d)
on installation of valve which must be noted and approved by
the contracting activity prior to manufacture of the first
valve.
(e)
Reference to any previous shock and vibration for valve and
test report numbers.
(f)
Details of the seat, disc, and stem assembly and all other
replaceable internal trim.
Recommended assembly torques, or equivalent procedures, for
(g)
making up all joints and threaded assemblies.
Table of seal dimensions and a tabulation of required gasket
(h)
characteristics including all dimensions (with tolerances)
and load versus compression characteristics (with tolerances).
Table of spring data.
(i)
Designed flow coefficient.
(k)
Mark areas to be radiographer, magnetic particle or liquid
penetrant inspected.
(l)
identify all weld joint types.
