An industrial plant providing liquid natural gas (LNG) to residential and commercial customers was expanding capacity and required a fireproofing solution for 9 process vessels.  The increase in demand for LNG, and the added market for Compressed Natural Gas to run commercial fleets of trucks and equipment, led to this expansion project. 

The 9 process vessels needed a fireproofing solution that would provide a one-hour rating in accordance with UL 1709 Hydro-Carbon Fire, as well as a sixty-minute rating in accordance with ISO 22891-1 for Jet Fire exposures. 

The steel vessel exteriors were prepared to an SSPC SP10 Near-White Blast, and an SSPC SP16 Brush-Off Blast cleaning of the stainless steel and other non-ferrous metals on the stainless steel vessels.  

The vessels then received 1 coat of Carboguard 893 SG Polyamide Epoxy.  After priming, Pyroclad X1 was spray applied using plural spray equipment with a High Temp Mesh being laid out at about 2/3 of the way into the resins to increase the integrity of the system.  

This process was followed by the application of the remaining mils of Pyroclad X1, and then finished with a topcoat of Carbothane 134 HG for the final colour and UV resistance.  The combined thickness was 396 mils (10mm) of Pyroclad X1.
