This Practice provides fabrication and installation details and dimensional tolerances for the design of supports and other attachments for vessels, heat exchangers and solids products containers.

This Practice describes typical fabrication and installation requirements for the following:

a. Nameplate

b. Vessel fabrication tolerances and connection orientation tolerances

c. Grounding lugs

d. Horizontal vessel saddle supports

e. Vertical vessel skirts

f. Vertical vessel leg type supports

g. Vertical vessel support lugs

h. Manway and column davits

i. Pipe supports and guides from vessels

j. Insulation and fireproofing supports

k. Vessel internals

l. Heat exchanger tube sheet locking studs and vents/drains

m. Studded joints

n. Solids product container internals and manways

This Practice includes all 32 standard details applicable to the fabrication and installation of vessels and shell-and-tube heat exchangers plus an index of standard details titles. Each detail is also assigned a PIP document number (VEFV1101 through VEFV1132) for ease of reference. The details in this Practice are in metric units. These details are mandatory when referenced in other PIP Practices. Those not referenced may be used at the discretion of the Designer (when specified on the Data Sheet) or at the Manufacturer’s option. The details cover the more common accessories attached to vessels and heat exchangers.
