scope:

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

Purpose

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.
