Description / Abstract:
This Practice must be used in conjunction with PIP
VEDST003, and PIP VEFV1100 (applicable
details), in order to comprise a complete heat exchanger
purchase specification.
Many recognized and generally accepted good engineering
construction practices are included herein. However, in light of
the many diverse service applications of Code vessels,
these practices must be employed with engineering judgment and
supplemented as appropriate with requirements related to specific
materials of construction, service fluids, operating environments,
and heat exchanger geometries. Accordingly, provisions of this
Practice may be overridden or supplemented by an Overlay
Specification.
Standardized pre-designed (off-the-shelf) heat exchangers are
not within the scope of this Practice, but are covered in PIP
VESSM001.
Heat exchangers with layered construction are outside the scope
of this Practice.
Purpose
The primary focus of this Practice is to communicate heat
exchanger design and fabrication criteria and methodology from the
User to a Designer and/or the Manufacturer. This Practice is also
intended as guidance for the development of purchase specifications
covering the construction of new shell-and-tube heat exchangers
which meet the philosophy and requirements of Section VIII,
Division 1 {or 2} of the Code and TEMA Standards of the Tubular
Exchangers Manufacturers Association.
