Refinery pipe coatings to minimize soot build-up

October 27, 2009

Please help.

We have a problem with build up of soot / slag with our furnace piping in our refinery. We use the following substrates.

1. High Alloy Steel for Anti-slag (soot build up, this is VERY important), high emissivity,
with Temperature acceptance 1100*C to 1300*C

2. Carbon steel / 20G(GB5310) (soot build up, this is VERY important), high emissivity,
with Temperature acceptance <430.

3. High Alloy steel / 12Cr1MoV (soot build up, this is VERY important), high emissivity,
with Temperature acceptance 570.
