RIGHT The steel for the fractionator arrived "black" at the shop and was first abrasive-blasted to NACE No. 2/ SSPC-SP 10 standard for Near White. additional assets around the original fire. To prevent this, the installation of passive fire protection is a significant cost of construction for these types of facilities. Additionally, given the fact that the materials are, in 99% of cases, applied more cost-effectively in a shop environment, the steel required for erection, from a cost standpoint, should be fireproofed before erection. Fireproofing is in the critical path of project completion. Unfortunately, this step is often completely overlooked by construction engineers and managers, because the materials are seen as "just paint" or "just concrete. " So the fireproofing occurs at a later stage. For this job, the owners decided that, prior to shipping the steel to the field, there would be a shop application of coating. Larry Nichols, PKI's marketing manager, explains exactly how the shop application part of the process works: "The services of fireproofing steel structures for these units involved shop and field application. So for a brief definition of process: Steel from a supplier is received 'black.' It is abrasive blasted and primed in the shop. The connections (where steel will be joined) are blocked-out, and intumescent fireproofing is applied by spray and hand trowel per specific application specifications. "Next, the module shop connects the steel into modules, and hand trowels intumescent at these connections, then applies a top coat. Once the modules are completed, they are transported into the facility and affixed to the stick steel—the supporting steel erected in the facility to hold the modular structures that house the individual processing units. As the units of completed modules in the facility are installed, intumescent fireproofing is hand troweled and completed Write in Reader Inquiry #142 70 CoatingsPro J July 2012
