Its primary job is to distribute massive tensile loads from the anchor bolts into the shell of the structure. You will most commonly find them at the base of: Vertical process vessels Storage tanks Tall chimneys Heavy industrial columns
AISI E1 Volume II Part VII provides detailed guidelines for the design, testing, and installation of anchor bolt chairs. The guidelines cover the following aspects: aisi e 1 volume ii part vii anchor bolt chairs better
Increasing the height of the vertical stiffeners is often better than increasing their thickness. A taller stiffener distributes the load over a larger area of the vessel shell, drastically reducing the risk of shell buckling. Match Bolt Tolerances Its primary job is to distribute massive tensile
Generic bolts often have damaged galvanizing due to field welding. Part VII chairs are typically fabricated from G60/G90 galvanized steel with specific weld requirements that preserve the coating. A taller stiffener distributes the load over a
