What is the required TFIFRM thickness reading for a pipe column?

The required thickness reading for a pipe column, indicated as a value of 24, is determined based on various factors, including the fire resistance rating needs, the structural load distribution, and the specific fireproofing standards applicable to the material and environment. Typically, for pipe columns that are part of structural systems, the fireproofing must meet requirements that take into account the temperature ratings and the expected fire conditions they may face.

The thickness of 24 is often a standard that ensures sufficient thermal protection to maintain structural integrity during a fire event. This thickness is calculated to provide adequate time for evacuation and to prevent structural failure by keeping the temperature of the steel components below critical limits.

In practice, this thickness allows for a margin that accommodates variations in application, material effectiveness, and the specific conditions the pipe column may experience. Therefore, a reading of 24 is aligned with industry standards for ensuring that pipe columns can endure the fire load they're designed to resist, maintaining safety and compliance with structural integrity certifications without being excessively heavy or costly.
