After cleaning, the opening points are sealed ready for leak test and nitrogen purging. 3.5 Leak Test and Nitrogen Purge After cleaning, all valves, blind flanges, caps and connected piping are installed and a leak test is performed at 4 bar using Nitrogen. The vessel will be delivered in a Nitrogen purged condition. Dry nitrogen will be used (O2 < 1% residual oxygen, 1,0 bar pressure, Nitrogen dew point - 20 C). 3.6 Painting (Hempel or equivalent Approved System) The carbon steel frame components are shotblasted to SA 2½ and painted as follows: First coat Hempadur Zinc (15360) 40 micron min DFT Intermediate coat Hempadur Primer (15553) 40 micron min DFT Final coat Hempathane (55210) 50 micron min DFT TOTAL 130 micron min DFT Colour: Turquoise Blue (RAL5018) The exterior of the tank to be degreased before application of paint. First coat Hempadur Zinc (15360) 40 micron min DFT Intermediate coat Hempadur Primer (15553) 40 micron min DFT Final coat Hempathane (55210) 50 micron min DFT TOTAL 130 micron min DFT Colour: White (Hempel 10000)
