Note : This video was taken after the second primer coat of approximately 50 mils DFT and before it had finished steaming off to complete its cure down. This video is courtesy of Doug Robinson, the Health and Safety Officer at Vancouver Shipyards.
 HPC Tiger Torch HPC Start
A piece of 8 " Schedule 40 pipe was preheated with a Tiger Torch.
HPC Start Prime Coat HPC Second Prime Coat
A temperature reduction from 350C on the bare pipe to 170C
after the initial primer coat @ 50 mils DFT was applied.
HPC Second Prime Coat 2 HPC Second Prime Coat Finished
A temperature reduction from 370C on the bare pipe to 90C
after the second primer coat @ 50 mils DFT was applied. ( Video )
HPC Training HPC Build Coat
A temperature reduction from 395C on the bare pipe to 55C
after the build coat @ 100 mils DFT was applied.
HPC Build Coat HPC Final Build Coat
A temperature reduction from 400C on the bare pipe to 50C
after the final build coat @ 250 mils DFT TOTAL was applied.
 HPC Cure Down HPC Touch
Of significant interest is the fact that Hot Pipe Coating can be applied to an in service surface without the necessity of an expensive shut down of operations. This applies to both initial application and any maintenance.
